Subject: [PATCH 4/9] usb: core: add power sequence handling for USB devices
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

+The generic power sequence library
+
+Some hard-wired devices (eg USB/MMC) need to do power sequence before
+the device can be enumerated on the bus, the typical power sequence
+like: enable USB PHY clock, toggle reset pin, etc. But current
+Linux device driver lacks of such code to do it, it may cause some
+hard-wired devices works abnormal or can't be recognized by
+controller at all. The power sequence will be done before this device
+can be found at the bus.
+
+The power sequence properties is under the device node.
+
+Optional properties:
+- clocks: the input clocks for device.
+- reset-gpios: Should specify the GPIO for reset.
+- reset-duration-us: the duration in microsecond for assert reset signal.
+
+Below is the example of USB power sequence properties on USB device
+nodes which have two level USB hubs.

+ vbus-supply = <&reg_usb_otg1_vbus>;

Subject: [PATCH 2/9] power: add power sequence library
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with
DT's, and choose this library at runtime.

+====================================
+Power Sequence Library
+====================================
+
+:Date: Feb, 2017
+:Author: Peter Chen <peter.chen@nxp.com>
+
+
+Introduction
+============
+
+We have an well-known problem that the device needs to do a power
+sequence before it can be recognized by related host, the typical
+examples are hard-wired mmc devices and usb devices. The host controller
+can't know what kinds of this device is in its bus if the power
+sequence has not done, since the related devices driver's probe calling
+is determined by runtime according to eunumeration results. Besides,
+the devices may have custom power sequence, so the power sequence library
+which is independent with the devices is needed.
+
+Design
+============
+
+The power sequence library includes the core file and customer power
+sequence library. The core file exports interfaces are called by
+host controller driver for power sequence and customer power sequence
+library files to register its power sequence instance to global
+power sequence list. The custom power sequence library creates power
+sequence instance and implement custom power sequence.
+
+Since the power sequence describes hardware design, the description is
+located at board description file, eg, device tree dts file. And
+a specific power sequence belongs to device, so its description
+is under the device node, please refer to:
+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt
+
+Custom power sequence library allocates one power sequence instance at
+bootup periods using postcore_initcall, this static allocated instance is
+used to compare with device-tree (DT) node to see if this library can be
+used for the node or not. When the result is matched, the core API will
+try to get resourses (->get, implemented at each library) for power
+sequence, if all resources are got, it will try to allocate another
+instance for next possible request from host driver.
+
+Then, the host controller driver can carry out power sequence on for this
+DT node, the library will do corresponding operations, like open clocks,
+toggle gpio, etc. The power sequence off routine will close and free the
+resources, and is called when the parent is removed. And the power
+sequence suspend and resume routine can be called at host driver's
+suspend and resume routine if needed.
+
+The exported interfaces

Subject: [PATCH 4/9] usb: core: add power sequence handling for USB devices
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

Subject: [PATCH 6/9] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB property
The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

Previously the onboard hub was made to work by treating its

+The generic power sequence library

+Some hard-wired devices (eg USB/MMC) need to do power sequence before

+like: enable USB PHY clock, toggle reset pin, etc. But current
+Linux device driver lacks of such code to do it, it may cause some
+hard-wired devices works abnormal or can't be recognized by
+controller at all. The power sequence will be done before this device
+can be found at the bus.
+
+The power sequence properties is under the device node.
+
+Optional properties:
+- clocks: the input clocks for device.
+- reset-gpios: Should specify the GPIO for reset.
+- reset-duration-us: the duration in microsecond for assert reset signal.
+
+Below is the example of USB power sequence properties on USB device
+nodes which have two level USB hubs.

Subject: [PATCH 2/9] power: add power sequence library
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with
DT's, and choose this library at runtime.

+====================================
+Power Sequence Library
+====================================
+
+:Date: Feb, 2017
+:Author: Peter Chen <peter.chen@nxp.com>
+
+
+Introduction
+============
+
+We have an well-known problem that the device needs to do a power
+sequence before it can be recognized by related host, the typical
+examples are hard-wired mmc devices and usb devices. The host controller
+can't know what kinds of this device is in its bus if the power
+sequence has not done, since the related devices driver's probe calling
+is determined by runtime according to eunumeration results. Besides,
+the devices may have custom power sequence, so the power sequence library
+which is independent with the devices is needed.
+
+Design
+============
+
+The power sequence library includes the core file and customer power
+sequence library. The core file exports interfaces are called by
+host controller driver for power sequence and customer power sequence
+library files to register its power sequence instance to global
+power sequence list. The custom power sequence library creates power
+sequence instance and implement custom power sequence.
+
+Since the power sequence describes hardware design, the description is
+located at board description file, eg, device tree dts file. And
+a specific power sequence belongs to device, so its description
+is under the device node, please refer to:
+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt
+
+Custom power sequence library allocates one power sequence instance at
+bootup periods using postcore_initcall, this static allocated instance is
+used to compare with device-tree (DT) node to see if this library can be
+used for the node or not. When the result is matched, the core API will
+try to get resourses (->get, implemented at each library) for power
+sequence, if all resources are got, it will try to allocate another
+instance for next possible request from host driver.
+
+Then, the host controller driver can carry out power sequence on for this
+DT node, the library will do corresponding operations, like open clocks,
+toggle gpio, etc. The power sequence off routine will close and free the
+resources, and is called when the parent is removed. And the power
+sequence suspend and resume routine can be called at host driver's
+suspend and resume routine if needed.
+
+The exported interfaces

From a42362841fe263a6c97a1793ccd4b9246ac2b108 Mon Sep 17 00:00:00 2001
From: Peter Chen <peter.chen@nxp.com>
Date: Thu, 18 May 2017 08:49:00 +0800
Subject: [PATCH 4/9] usb: core: add power sequence handling for USB devices
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

Subject: [PATCH 6/9] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB property
The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

Subject: [PATCH 7/9] ARM: dts: imx6q-evi: Fix onboard hub reset line
Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support

+The generic power sequence library
+
+Some hard-wired devices (eg USB/MMC) need to do power sequence before
+the device can be enumerated on the bus, the typical power sequence
+like: enable USB PHY clock, toggle reset pin, etc. But current
+Linux device driver lacks of such code to do it, it may cause some
+hard-wired devices works abnormal or can't be recognized by
+controller at all. The power sequence will be done before this device
+can be found at the bus.
+
+The power sequence properties is under the device node.
+
+Optional properties:
+- clocks: the input clocks for device.
+- reset-gpios: Should specify the GPIO for reset.
+- reset-duration-us: the duration in microsecond for assert reset signal.
+
+Below is the example of USB power sequence properties on USB device
+nodes which have two level USB hubs.

Subject: [PATCH 2/9] power: add power sequence library
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with
DT's, and choose this library at runtime.

+====================================
+Power Sequence Library
+====================================
+
+:Date: Feb, 2017
+:Author: Peter Chen <peter.chen@nxp.com>
+
+
+Introduction
+============
+
+We have an well-known problem that the device needs to do a power
+sequence before it can be recognized by related host, the typical
+examples are hard-wired mmc devices and usb devices. The host controller
+can't know what kinds of this device is in its bus if the power
+sequence has not done, since the related devices driver's probe calling
+is determined by runtime according to eunumeration results. Besides,
+the devices may have custom power sequence, so the power sequence library
+which is independent with the devices is needed.
+
+Design
+============
+
+The power sequence library includes the core file and customer power
+sequence library. The core file exports interfaces are called by
+host controller driver for power sequence and customer power sequence
+library files to register its power sequence instance to global
+power sequence list. The custom power sequence library creates power
+sequence instance and implement custom power sequence.
+
+Since the power sequence describes hardware design, the description is
+located at board description file, eg, device tree dts file. And
+a specific power sequence belongs to device, so its description
+is under the device node, please refer to:
+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt
+
+Custom power sequence library allocates one power sequence instance at
+bootup periods using postcore_initcall, this static allocated instance is
+used to compare with device-tree (DT) node to see if this library can be
+used for the node or not. When the result is matched, the core API will
+try to get resourses (->get, implemented at each library) for power
+sequence, if all resources are got, it will try to allocate another
+instance for next possible request from host driver.
+
+Then, the host controller driver can carry out power sequence on for this
+DT node, the library will do corresponding operations, like open clocks,
+toggle gpio, etc. The power sequence off routine will close and free the
+resources, and is called when the parent is removed. And the power
+sequence suspend and resume routine can be called at host driver's
+suspend and resume routine if needed.
+
+The exported interfaces

From a42362841fe263a6c97a1793ccd4b9246ac2b108 Mon Sep 17 00:00:00 2001
From: Peter Chen <peter.chen@nxp.com>
Date: Thu, 18 May 2017 08:49:00 +0800
Subject: [PATCH 4/9] usb: core: add power sequence handling for USB devices
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

Subject: [PATCH 7/9] ARM: dts: imx6q-evi: Fix onboard hub reset line
Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support
Move pin muxing the hub reset pin into the usbh1 group

+The generic power sequence library
+
+Some hard-wired devices (eg USB/MMC) need to do power sequence before
+the device can be enumerated on the bus, the typical power sequence
+like: enable USB PHY clock, toggle reset pin, etc. But current
+Linux device driver lacks of such code to do it, it may cause some
+hard-wired devices works abnormal or can't be recognized by
+controller at all. The power sequence will be done before this device
+can be found at the bus.
+
+The power sequence properties is under the device node.
+
+Optional properties:
+- clocks: the input clocks for device.
+- reset-gpios: Should specify the GPIO for reset.
+- reset-duration-us: the duration in microsecond for assert reset signal.
+
+Below is the example of USB power sequence properties on USB device
+nodes which have two level USB hubs.

Subject: [PATCH 2/9] power: add power sequence library
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with

+====================================
+Power Sequence Library
+====================================
+
+:Date: Feb, 2017
+:Author: Peter Chen <peter.chen@nxp.com>
+
+
+Introduction
+============
+
+We have an well-known problem that the device needs to do a power
+sequence before it can be recognized by related host, the typical
+examples are hard-wired mmc devices and usb devices. The host controller
+can't know what kinds of this device is in its bus if the power
+sequence has not done, since the related devices driver's probe calling
+is determined by runtime according to eunumeration results. Besides,
+the devices may have custom power sequence, so the power sequence library
+which is independent with the devices is needed.
+
+Design
+============
+
+The power sequence library includes the core file and customer power
+sequence library. The core file exports interfaces are called by
+host controller driver for power sequence and customer power sequence
+library files to register its power sequence instance to global
+power sequence list. The custom power sequence library creates power
+sequence instance and implement custom power sequence.
+
+Since the power sequence describes hardware design, the description is
+located at board description file, eg, device tree dts file. And
+a specific power sequence belongs to device, so its description
+is under the device node, please refer to:
+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt
+
+Custom power sequence library allocates one power sequence instance at
+bootup periods using postcore_initcall, this static allocated instance is
+used to compare with device-tree (DT) node to see if this library can be
+used for the node or not. When the result is matched, the core API will
+try to get resourses (->get, implemented at each library) for power
+sequence, if all resources are got, it will try to allocate another
+instance for next possible request from host driver.
+
+Then, the host controller driver can carry out power sequence on for this
+DT node, the library will do corresponding operations, like open clocks,
+toggle gpio, etc. The power sequence off routine will close and free the
+resources, and is called when the parent is removed. And the power
+sequence suspend and resume routine can be called at host driver's
+suspend and resume routine if needed.
+
+The exported interfaces

Subject: [PATCH 7/9] ARM: dts: imx6q-evi: Fix onboard hub reset line
Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support
Move pin muxing the hub reset pin into the usbh1 group

Subject: arch: arm64: dts: amlogic: add wifi/bt support to bananapi m5
The BPI-M5 has an optional RTL8822CS WiFi/BT mezzanine board. Describe
the board but mark the sd_emmc_a and uart_A nodes disabled so they can
be enabled via overlay or fdtput when the board is connected.

Subject: LOCAL: usb: hub: disable autosuspend for Genesys Logic Hubs
Disable autosuspend in Genesys Logic hubs to allow USB devices on the
Odroid C2 board to be used. The alternative to this patch is setting
usbcore.autosuspend=-1 in boot params.
This patch only impacts GXBB devices as GXL/GXM onwards use the newer
dwc3 core which does not have the problem.
