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 <rabeeh@solid-run.com> [tweaked alias for pwm pinctrl group --rmk] Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
