From 681db972d03bb40370e9f69eeb2f47e871a6f920 Mon Sep 17 00:00:00 2001 From: Christian Hewitt Date: Sun, 27 Dec 2020 15:11:59 +0000 Subject: [PATCH 46/58] arm64: dts: meson: add initial device-tree for Bananapi BPI-M5 The Bananapi Wiki links to Amlogic BSP kernel sources which show [0] BPI-M5 to be aligned with the HardKernel ODROID-C4 device-tree with relatively minor differences: - 1x Green LED - 4x Switches labelled SW1/RST/SW3/SW4 - 3.5mm A/V connector - USB-C power connector (5V) [0] https://github.com/Dangku/amlogic-linux/commit/bddc95f88a07e7e66f73192d8307af5b547c5b32 Signed-off-by: Christian Hewitt --- arch/arm64/boot/dts/amlogic/Makefile | 1 + .../dts/amlogic/meson-sm1-bananapi-m5.dts | 63 +++++++++++++++++++ 2 files changed, 64 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-bananapi-m5.dts diff --git a/arch/arm64/boot/dts/amlogic/Makefile b/arch/arm64/boot/dts/amlogic/Makefile index aebd49c88719..da11ef28a47b 100644 --- a/arch/arm64/boot/dts/amlogic/Makefile +++ b/arch/arm64/boot/dts/amlogic/Makefile @@ -46,6 +46,7 @@ dtb-$(CONFIG_ARCH_MESON) += meson-gxm-rbox-pro.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-s912-libretech-pc.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-vega-s96.dtb dtb-$(CONFIG_ARCH_MESON) += meson-gxm-wetek-core2.dtb +dtb-$(CONFIG_ARCH_MESON) += meson-sm1-bananapi-m5.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-sei610.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-khadas-vim3l.dtb dtb-$(CONFIG_ARCH_MESON) += meson-sm1-odroid-c4.dtb diff --git a/arch/arm64/boot/dts/amlogic/meson-sm1-bananapi-m5.dts b/arch/arm64/boot/dts/amlogic/meson-sm1-bananapi-m5.dts new file mode 100644 index 000000000000..a98301777622 --- /dev/null +++ b/arch/arm64/boot/dts/amlogic/meson-sm1-bananapi-m5.dts @@ -0,0 +1,63 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2020 Christian Hewitt + */ + +/dts-v1/; + +#include "meson-sm1-odroid-c4.dts" + +/ { + compatible = "sinovoip,bananapi-m5", "amlogic,sm1"; + model = "Bananapi BPI-M5"; + + leds { + compatible = "gpio-leds"; + + blue { + color = ; + function = LED_FUNCTION_STATUS; + gpios = <&gpio_ao GPIOAO_11 GPIO_ACTIVE_LOW>; + linux,default-trigger = "heartbeat"; + panic-indicator; + }; + + green { + color = ; + function = LED_FUNCTION_STATUS; + gpios = <&gpio_ao GPIOAO_2 GPIO_ACTIVE_LOW>; + default-state = "off"; + }; + }; + + hub_5v: regulator-hub_5v { + compatible = "regulator-fixed"; + regulator-name = "HUB_5V"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + vin-supply = <&vcc_5v>; + + /* Connected to the Hub CHIPENABLE, LOW sets low power state */ + gpio = <&gpio GPIOH_4 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; +}; + +&gpio { + /* + * WARNING: The USB Hub on the Bananapi M5 needs a reset signal + * to be turned high in order to be detected by the USB Controller + * This signal should be handled by a USB specific power sequence + * in order to reset the Hub when USB bus is powered down. + */ + usb-hub { + gpio-hog; + gpios = ; + output-high; + line-name = "usb-hub-reset"; + }; +}; + +&ir { + linux,rc-map-name = "rc-odroid"; +}; -- 2.25.1
