+
+Allwinner H6 PWM is similar to that in A20 except that it has additional
+bus clock and reset line.
+
+Note that first PWM channel is connected to output pin and second
+channel is used internally, as a clock source to AC200 co-packaged chip.
+This means that any combination of these two channels can be used and
+thus it doesn't make sense to add pinctrl nodes at this point.
