From: Tomasz Maciej Nowak <tmn505@xxxxxxxxx> Pins responsible for controlling these LEDs need to have tristate control removed if we want them as GPIOs. This change alings with pinmux configuration of "dte" pin group in downstream kernel[1]. These LEDs had no function assigned on vendor kernel and there is no label on the case, the only markings are on PCB which are part of node names (ds1 marking is on power LED controlled by PMIC), so generic term is assigned as the function. 1. https://github.com/compulab/trimslice-android-kernel/blob/upstream/arch/arm/mach-tegra/board-trimslice-pinmux.c#L45 Signed-off-by: Tomasz Maciej Nowak <tmn505@xxxxxxxxx> --- Previous version: https://lore.kernel.org/linux-tegra/20180219201623.6987-1-tmn505@xxxxxxxxx Changes in v2: - rebase - reword commit title and message - align to changes in leds subsystem - align to dtschema recomendations .../arm/boot/dts/nvidia/tegra20-trimslice.dts | 30 +++++++++++++++---- 1 file changed, 25 insertions(+), 5 deletions(-) diff --git a/arch/arm/boot/dts/nvidia/tegra20-trimslice.dts b/arch/arm/boot/dts/nvidia/tegra20-trimslice.dts index 7cae6ad57544..4caeeb9f1e1d 100644 --- a/arch/arm/boot/dts/nvidia/tegra20-trimslice.dts +++ b/arch/arm/boot/dts/nvidia/tegra20-trimslice.dts @@ -2,6 +2,7 @@ /dts-v1/; #include <dt-bindings/input/input.h> +#include <dt-bindings/leds/common.h> #include "tegra20.dtsi" #include "tegra20-cpu-opp.dtsi" @@ -201,16 +202,17 @@ uca { conf_ata { nvidia,pins = "ata", "atc", "atd", "ate", "crtp", "dap2", "dap3", "dap4", "dta", - "dtb", "dtc", "dtd", "dte", "gmb", - "gme", "i2cp", "pta", "slxc", "slxd", - "spdi", "spdo", "uda"; + "dtb", "dtc", "dtd", "gmb", "gme", + "i2cp", "pta", "slxc", "slxd", "spdi", + "spdo", "uda"; nvidia,pull = <TEGRA_PIN_PULL_NONE>; nvidia,tristate = <TEGRA_PIN_ENABLE>; }; conf_atb { nvidia,pins = "atb", "cdev1", "cdev2", "dap1", - "gma", "gmc", "gmd", "gpu", "gpu7", - "gpv", "sdio1", "slxa", "slxk", "uac"; + "dte", "gma", "gmc", "gmd", "gpu", + "gpu7", "gpv", "sdio1", "slxa", "slxk", + "uac"; nvidia,pull = <TEGRA_PIN_PULL_NONE>; nvidia,tristate = <TEGRA_PIN_DISABLE>; }; @@ -408,6 +410,24 @@ key-power { }; }; + leds { + compatible = "gpio-leds"; + + led-ds2 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_INDICATOR; + function-enumerator = <2>; + gpios = <&gpio TEGRA_GPIO(D, 2) GPIO_ACTIVE_LOW>; + }; + + led-ds3 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_INDICATOR; + function-enumerator = <3>; + gpios = <&gpio TEGRA_GPIO(BB, 5) GPIO_ACTIVE_LOW>; + }; + }; + poweroff { compatible = "gpio-poweroff"; gpios = <&gpio TEGRA_GPIO(X, 7) GPIO_ACTIVE_LOW>; -- 2.46.0
