2024-03-02	dt-bindings: pwm: amlogic: Add a new binding for meson8 pwm types	Jerome Brunet	1	-3/+47
	The binding that is used up to now describe which input the PWM channel multiplexer should pick among its possible parents, which are hardcoded in the driver. This isn't a good binding in the sense that it should describe hardware but not usage. Add a new binding deprecating the old one that uses clocks in a better way and how clocks are usually used today: The list of clocks describe the inputs of the PWM block as they are realised in hardware. So deprecate the old bindings and introduce a compatible per SoC family to replace these.

2024-03-02	dt-bindings: pwm: amlogic: fix s4 bindings	Jerome Brunet	1	-9/+58
	s4 has been added to the compatible list while converting the Amlogic PWM binding documentation from txt to yaml. However, on the s4, the clock bindings have different meaning compared to the previous SoCs. On the previous SoCs the clock bindings used to describe which input the PWM channel multiplexer should pick among its possible parents. This is very much tied to the driver implementation, instead of describing the HW for what it is. When support for the Amlogic PWM was first added, how to deal with clocks through DT was not as clear as it nowadays. The Linux driver now ignores this DT setting, but still relies on the hard-coded list of clock sources. On the s4, the input multiplexer is gone. The clock bindings actually describe the clock as it exists, not a setting. The property has a different meaning, even if it is still 2 clocks and it would pass the check when support is actually added. Also the s4 cannot work if the clocks are not provided, so the property is no longer optional. Finally, for once it makes sense to see the input as being numbered somehow. No need to bother with clock-names on the s4 type of PWM.
