* pwm: Add MediaTek display PWM driver supportYH Huang2015-10-061-0/+243
Add display PWM driver support to modify backlight for MT8173 and MT6595. The PWM has one channel to control the brightness of the display. When the (high_width / period) is closer to 1, the screen is brighter; otherwise, it is darker.
