[PATCH v2 2/2] ARM: dts: rockchip: enable pwm3 as pwm regulator for rk3066a based boards

From: Andy Yan
Date: Fri Jan 15 2016 - 08:26:48 EST


Rayeager/Bqcurie2/Marsboard use pwm3 modulate the vdd_logic voltage,
so enable it.

Changes in v2:
- also enable the pwm regulator for bqcurie2 and Marsboard
