So the A64 PWM seems to be fully compatible with the H3 one, which has a
documented binding (also used in the Linux driver).
So can you please make this:
		compatible = "allwinner,sun50i-a64-pwm",
			     "allwinner,sun8i-h3-pwm";

and then drop the sun50i-a64-pwm string in the driver?

And I wonder if we should have the pinctrl already in here, since there
is only one choice for PWM0? At least that would document the clash.
