pmbus based power regulator

[Michal Simek <michal.simek@xxxxxxxxxx>]

Hi,

I have one question about hwmon/pmbus. I have tps544b25 on the board. I
have enabled this chip via DT to get probed. Patch below.

I can't see any issue with monitoring but I am curious how to enable
setting up voltage. I expect this should be moved to regulator folder or
better split done as MFD device.

I see there wm831x-hwmon and also wm8350-hwmon but nothing with pmbus
wiring.
Can you please suggest a way how this should be done?

Thanks,
Michal

    hwmon: pmbus: Add DT wiring for ti,tps544b25

    This should be enough for DT wiring to get generic functionality.
