2019-03-04pwm: Add MediaTek MT8183 display PWM driver supportJitao Shi1-0/+11
Use the mtk_pwm_data struction to define different registers and add MT8183 specific register operations, such as MT8183 doesn't have commit register, needs to disable double buffer before writing register, and needs to select commit mode and use PWM_PERIOD/PWM_HIGH_WIDTH.

2015-10-06pwm: Add MediaTek display PWM driver supportYH Huang1-0/+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. Signed-off-by: YH Huang <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
