On the RK3066, there is a bit that must be cleared on flush, otherwise
we do not get display output (at least for RGB).

Hi! This was required to get display working on an old RK3066 tablet,
along with the next tiny patch in the series

What commit id does this fix?
I guess
old Rockchip RK3066 tablet, and it did fix
the problem :) Thank you.

The RK3066 does have RGB display output, so it should be marked as such.

do it, since it indicates exactly that: that the hardware is done
with the frame.
This seems to be a redundant synchronization mechanism that was removed
in later iterations of the VOP hardware block.

This tiny patch series makes the changes required to enable the RGB
display output on the Rockchip RK3066 SoC. Final version as discussed.

The RK3066 VOP sets a dma_stop bit when it's done scanning out a frame
and needs the driver to acknowledge that by clearing the bit.
So unless we clear it "between" frames, the RGB output only shows
noise
instead
Cannot confirm which variant exactly it is, as the EDID alphanumeric data
contains '0RGNR' <0x80> 'NE14QDM' and ends there; but it's 60 Hz and with
touch.
I do not have access to datasheets for these panels, so the timing is
a guess that was tested to work fine on t
s how it worked before.

As this fix is tiny, if you prefer to fix it differently somehow, feel free to
just redo it yourselves
