[PATCH v3 1/2] arm64: dts: rockchip: Add pwm nodes for RK3528
Posted by Chukun Pan 1 month, 2 weeks ago 
Add pwm nodes for RK3528. The PWM core on RK3528 is the same as
RK3328, but the driver does not support interrupts yet.

pwm0-pwm2 has been verified working on my rk3528 boards and remaining
seem to be correct, I have also dropped my prior attempt of looking into
multi-channel handling as mentioned in v2, so this is:
