From: Jernej Skrabec <jernej.skrabec@siol.net>
|
||||
|
||||
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.
