This series adds HDMI support for JZ4780 and CI20 board
V2:
- code and commit messages revisited for checkpatch warnings
- rebased on v5.14-rc4
- include (failed, hence RFC 8/8) attempt to convert to component framework
(was suggested by Paul Cercueil a while ago)

Hi Paul,
we observed the same issue on the jz4730 (which is almost identical
to the jz4740 wrt. LCDC) and our solution [1] was simpler.
It leaves the hwdesc f0 and f1 as they are and just takes f1 for really
programming the first DMA descriptor if there is no OSD.
We have tested on jz4730 and jz4

Indeed. And since we h
Hi Paul,
thanks for another update.
We have been delayed to rework the CI20 HDMI code on top of your series
but it basically works in some situations. There is for example a problem
if the EDID reports DRM_COLOR_FORMAT_YCRCB422 but it appears to be outside
of your series.
The only issue we have i

Since I don't know details of the DRM bridge/encoder/connector APIs),
let me reformulate the quersion for a condition specifically.

If ingenic drm driver can not be registered, the IPU driver won't be
deregistered.
Code structure is chosen in preparation to add hdmi unregistration

call this.
