I had started working on the regulator and while testing and trying to read the EDID
something has damaged my monitor so that it does no longer report proper EDID information
(for the second time, so that I can't pledge for another warrany repair). Maybe controlling
+5V for this specific monitor must be done very carefully and in a specific sequence...

So I will need some more days for building a more robust test setup and doing verification
of the driver. Well I have other monitors, but this was the cheapest one and available
for such experiments :)

Generally the idea is to replace the regulator with a ddc-en-gpios property of the connector.

Unfortunately it does not work to control it by atomic enable/disable in the connector driver
(it is not called at all). So I have been working on an approach following the concept how
drivers/gpu/drm/sun4i/sun8i_dw_hdmi.c does it.

Sorry for the delay, but a V12 will come.

BR and thanks,
Nikolaus
