This is a collection of bridge patches that I had left unfinished
more than a year ago. Now where I have some spare time I dusted them
off for review and testing.
The patches builds, but has seen no run-time testing.
The patches are grouped like this:
1+2:
- Updates parade-ps8640 for atomic operation thus allowing
the use of the atomic variants of drm_bridge_chain_pre_enable/
post_disable.
There is thus no users left of the non-atomic variants of
drm_bridge_chain* so drop them all.
If other drivers needs this functionality they are supposed
to use the atomic API.
This is a DSI to eDP converter, and I did not see a need for
format negotiation - but I may be wrong?
3+4:
- Drop chain_mode_fixup in mediatek, and as there are no more
users, drop the implementation of drm_bridge_chain_mode_fixup.
The crucial part to review is the updated documentation for
drm_bridge_funcs.atomic_check().
5-11:
- Convert all bridge drivers from mode_fixup to atomic_check.
To do so add the necessary hooks to have an atomic state.
I think the drivers will work using the atomic API,
but it has seen no testing!
I did not see any need for format negotiation, but if needed
let me know so we can fix it.
The last patch removes the mode_fixup support in drm_bridge.
12:
- Add a few todo items, in the hope others will jump in and
convert some of the bridge drivers to the atomic API.
The patch groups are more or less independent, and I may land them out
of order if one group is reviewed before the rest.
A few of the patches has already seen a review, but they need a
bit more exposure as last review was more than a year ago.
