This series adds support for 4k@30 to the rockchip HDMI controller. This
has been tested on a rk3568 rock3a board. It should be possible to add
4k@60 support the same way, but it doesn't work for me, so let's add
4k@30 as a first step.

Thanks for the v2! On a RK3568 EVB1 with a HP 27f 4k monitor
Tested-by: Michael Riesch <michael.riesch@xxxxxxxxxxxxxx>
Sadly this still doesn't give my display out on my 2k monitor. Not even just
1080p picture like the old current implementation does.
By "like the old current implementation" you mean that this patchset
introduces a regression for you?
Yes. What currently in the kernel at least shows as 1080p on my 2K monitor,
while this patchset turns off the screen.
Which SoC are you testing this on? I assume RK3568, right? Which patch
introduces that regression, the first or the second one?
I tested on the Odroid M, which is rk3568.
I have only applied them both, as I was under the impression that both
are needed for the 4k support.
