Subject: [PATCH 0/6] pwm: sprd: Modification of UNISOC Platform PWM Driver

Due to new usage scenarios, some upgrades are made to unisoc's pwm driver.
Patch 1 supports the change of channel offset on UMS9620.
Patch 2 supports more brightness levels (duty cycle) for backlight control.
Patch 3 optimizes the calculation method of duty.
Patch 4 converts dt-binding file from txt to yaml
Patch 5-6 update pwm-sprd.yaml according to patch 1 and patch 2.

Wenhua Lin (6):
