[PATCH 6/7] ARM: dts: rockchip: add pwm nodes

Heiko Stübner heiko at sntech.de
Sat Jul 12 12:30:53 PDT 2014


From: Beniamino Galvani <b.galvani at gmail.com>

This adds the necessary nodex and pinctrl settings for the Rockchip PWM-driver.

Signed-off-by: Beniamino Galvani <b.galvani at gmail.com>

Modified to use the new clock defines and added rk3066 pins.
