This patch series add the use of display PWM driver, documentation
and device tree for Mediatek SoCs. The driver is used to support
the backlight of the panel. This is based on v4.2-rc1.

The clock definitions (CLK_MM_DISP_PWM*) are added by James Liao's patch:
clk: mediatek: Add subsystem clocks of MT8173

Change in v6:
1. Enable clocks in the pwm_enable function
2. Remove suspend/resume code since pwm-backlight driver has done the same things
3. Revise some code to make it easier to read

YH Huang (3):
dt-bindings: pwm: add MediaTek display PWM bindings
pwm: add MediaTek display PWM driver support
arm64: dts: mt8173: add MT8173 display PWM driver support node
