From ffbae6b719227662f3baca349d1e17ac7e652ec4 Mon Sep 17 00:00:00 2001 From: Rabeeh Khoury Date: Mon, 2 Mar 2015 20:03:59 +0000 Subject: ARM: dts: hummingboard: Setup pwm lines Setup pwm lines as follows - pwm1: In case HummingBoard base carrier; this pin drives through a serial capacitor the mono out of the audio jack. In case HummingBoard pro the this pad can be reached by wiring to C8 capacitors on the board. pwm2: Setup pwm2 on gpio-1 but leave the default function of the iopad as a gpio. The user can change the io pad mux in user space and therefore use this function on gpio-1 (pin number 7 on the 26 pin header). pwm3,pwm4: unused Signed-off-by: Rabeeh Khoury [tweaked alias for pwm pinctrl group --rmk] Signed-off-by: Russell King Signed-off-by: Shawn Guo --- arch/arm/boot/dts/imx6qdl-hummingboard.dtsi | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'arch/arm/boot/dts/imx6qdl-hummingboard.dtsi') diff --git a/arch/arm/boot/dts/imx6qdl-hummingboard.dtsi b/arch/arm/boot/dts/imx6qdl-hummingboard.dtsi index 93588c987d2c..7ee95223bf3d 100644 --- a/arch/arm/boot/dts/imx6qdl-hummingboard.dtsi +++ b/arch/arm/boot/dts/imx6qdl-hummingboard.dtsi @@ -164,6 +164,10 @@ >; }; + pinctrl_hummingboard_pwm1: pwm1grp { + fsl,pins = ; + }; + pinctrl_hummingboard_spdif: hummingboard-spdif { fsl,pins = ; }; @@ -203,6 +207,17 @@ }; }; +&pwm1 { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_hummingboard_pwm1>; + status = "okay"; +}; + +&pwm2 { + pinctrl-names = "default"; + status = "okay"; +}; + &spdif { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hummingboard_spdif>; -- cgit v1.2.3
