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
