The D25 LED controlled by gpio on the i.MX51 babbage board is a diagnostic LED according to the board design. This patch adds the relevant device tree nodes to the i.MX51 babbage device tree file to support this LED. Signed-off-by: Liu Ying <Ying.Liu@xxxxxxxxxxxxx> --- v1->v2: * Rebase the patch from 3.14-rc2 to linux-next(d371ca32be). * Rename the pinctrl name for the LED to be more generic. * Switch to use the standard GPIO flag GPIO_ACTIVE_HIGH. arch/arm/boot/dts/imx51-babbage.dts | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/arch/arm/boot/dts/imx51-babbage.dts b/arch/arm/boot/dts/imx51-babbage.dts index ea5c67e..121dadd 100644 --- a/arch/arm/boot/dts/imx51-babbage.dts +++ b/arch/arm/boot/dts/imx51-babbage.dts @@ -81,6 +81,17 @@ }; }; + leds { + compatible = "gpio-leds"; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_gpio_leds>; + + led-diagnostic { + label = "diagnostic"; + gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>; + }; + }; + sound { compatible = "fsl,imx51-babbage-sgtl5000", "fsl,imx-audio-sgtl5000"; @@ -344,6 +355,12 @@ >; }; + pinctrl_gpio_leds: gpioledsgrp { + fsl,pins = < + MX51_PAD_EIM_D22__GPIO2_6 0x80000000 + >; + }; + pinctrl_i2c2: i2c2grp { fsl,pins = < MX51_PAD_KEY_COL4__I2C2_SCL 0x400001ed -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
