8a5fe04495 net: ti: am65-cpsw-nuss: Add logic to support MDIO reset
Enhance the AM65 CPSW NUSS driver to perform a MDIO reset using a GPIO
line. Logic is also added to perform a pre and post delay around reset
using the optional 'reset-delay-us' and 'reset-post-delay-us' properties.
This is similar to the reset being performed in the Linux kernel. The
reset is done once when the CPSW MDIO bus is being initialized.

The PSIL endpoint data for J721E currently covers only the MCU domain
CPSW0 instance. Add the data for the MAIN domain CPSW0 as well to allow
the MAIN domain Ethernet ports to be usable on any platform using J721E
SoC.

Additionally, since J721E's PSIL endpoint data is applicable to J7200
SoC as well, the MAIN CPSW0 instance on J7200 will also be usable now.

250454c59b i2c: mvtwsi: reset controller if stuck in "bus error" state
The MVTWSI controller can act either as a master or slave device. When
acting as a master, the FSM is driven by the CPU. As a slave, the FSM is
driven by the bus directly. In what is (apparently) a safety mechanism,
if the bus transitions our FSM in any improper way, the FSM goes to a
"bus error" state (0x00). I could find no documented or experimental way
to get the FSM out of this state, except for a controller reset.

Since U-Boot only uses the MVTWSI controller as a bus master, this
feature only gets in the way: we do not care what happened on the bus
previously as long as the bus is ready for a new transaction. So, when
trying to start a new transaction, check for this state and reset the
controller if necessary.

Note that this should not be confused with the "deblocking" technique
(used by the `i2c reset` command), which involves pulsing SCL repeatedly
if SDA is found to be held low, in an attempt to force the bus back to
an idle state. This patch only resets the controller in case something
else had previously upset it, and (in principle) results in no
externally-observable change in behavior.

aaf5b59230 gpio: Use separate bitfield array to indicate GPIO is claimed
The current gpio-uclass design uses name field in struct gpio_dev_priv as
an indicator that GPIO is claimed by consumer. This overloads the function
of name field and does not work well for named pins not configured as GPIO
pins.

Introduce separate bitfield array as the claim indicator.

This unbreaks dual-purpose AF and GPIO operation on STM32MP since commit
2c38f7c31806 ("pinctrl: pinctrl_stm32: Populate uc_priv->name[] with pinmux node's name")
where any pin which has already been configured as AF could no longer be
claimed as dual-purpose GPIO. This is important for pins like STM32 MMCI
st,cmd-gpios .

d7009faa09 pinctrl: rockchip: Fix drive and input schmitt on RK3568
On RK3568 most pins have a configurable drive strength of level 0-5 and
some pins level 0-11. When rk3568_set_drive is called with a strength
value above 7 the drv value written to reg may overflow into the write
enable bits, resulting in a bad configuration.

This cause e.g. ethernet PHY on Radxa CM3-IO board not to work after
drive is configured according to the device tree.

  Could not get PHY for ethernet@fe010000: addr 0

Level 6-11 can be configured using a second reg for some pins, however
the drv value is reused resulting in lower 6 bits being written to reg.

Input schmitt is configured in 2-bit fields on RK3568 compared to
earlier generation and 2'b10 should be used to enable input schmitt.

Change to use regmap_update_bits with a rmask to fix the overflow issue
and closer match the linux driver. Bit shift the drv value used for the
second reg to configure drive strength level 6-11. Also write correct
values for input schmitt setting.

615828721a Revert "lib: string: Fix strlcpy return value", fix callers
Both the Linux kernel and libbsd agree that strlcpy() should always
return strlen(src) and not include the NUL termination. The incorrect
U-Boot implementation makes it impossible to check the return value for
truncation, and breaks code written with the usual implementation in
mind (for example, fdtdec_add_reserved_memory() was subtly broken).

I reviewed all callers of strlcpy() and strlcat() and fixed them
according to my understanding of the intended function.

This reverts commit d3358ecc54be0bc3b4dd11f7a63eab0a2842f772 and adds
related fixes.

f16a48fec9 arm_ffa: introduce armffa command
Provide armffa command showcasing the use of the U-Boot FF-A support

armffa is a command showcasing how to invoke FF-A operations.
This provides a guidance to the client developers on how to
call the FF-A bus interfaces. The command also allows to gather secure
partitions information and ping these  partitions. The command is also
helpful in testing the communication with secure partitions.

For more details please refer to the command documentation [1].

A Sandbox test is provided for the armffa command.

a09852d862 arm_ffa: introduce sandbox FF-A support
Emulate Secure World's FF-A ABIs and allow testing U-Boot FF-A support

Features of the sandbox FF-A support:

- Introduce an FF-A emulator
- Introduce an FF-A device driver for FF-A comms with emulated Secure World
- Provides test methods allowing to read the status of the inspected ABIs

The sandbox FF-A emulator supports only 64-bit direct messaging.

39d383bdac arm_ffa: introduce Arm FF-A support
Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0

The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.

This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.

The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.

All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.

Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.

The driver exports its operations to be used by upper layers.

Exported operations:

- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap

Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).

For more details please refer to the driver documentation [2].

718f1d414e usb: gadget: ether: Handle gadget driver registration in probe and remove
Move the ethernet gadget driver registration and removal from ethernet
bind and unbind callbacks into driver DM probe and remove callbacks.
This way, when the driver is bound, which is triggered deliberately
using 'bind' command, the USB ethernet gadget driver is instantiated
and bound to the matching UDC. In reverse, when the driver is unbound,
which is again triggered deliberately using 'unbind' command, the USB
ethernet gadget driver instance is removed.

Effectively, this now behaves like running either 'ums' or 'dfu' or
any other commands utilizing USB gadget functionality.

This also drops use of usb_gadget_release() and moves the use of
usb_gadget_initialize() into usb_ether_init() used only by legacy
platforms that do not use 'bind' command properly yet. Those have
no place in drivers.
