 You would need to provide a stable tag for me that I can merge into my 
 tree. You
 can also try to merge my for-next [1] which has the newest version from 
 Enric.
 If you see any merge conflict, then we have to do something about it :)

This series is in linux-next but does not in main stream. So would you
please provide a stable branch so I could pull this series?

In the end Enric rebased his branch on top of v5.6-rc1 so I won't take this

 This patch does not apply against v5.6-rc1.
 Please rebase as this is a quite big patch and it won't be easy to do that 
 by hand.

I haven't (yet) send the pull request. If you want to bring in your patches in
v5.7 as well we can find a solution to that. Shall I provide you with a stable
branch which you can merge? This way you can add all your patches in the pull
request as well and we don't have to wait for v5.8 to get things into mainline.

Let me know and I'll provide you with a stable branch.

Matthias

You would need to provide a stable tag for me that I can merge into my tree. You
can also try to merge my for-next [1] which has the newest version from Enric.
If you see any merge conflict, then we have to do something about it :)

You have applied this series, so I would not apply other patches which
would conflict with this series. After this series land on main stream
(wish it happen in this merge window), I would rebase other patch on
main stream.

[RESEND PATCH v12 4/5] soc / drm: mediatek: Move routing control to mmsys device

2020-03-26 Thread Enric Balletbo i Serra
Provide a mtk_mmsys_ddp_connect() and mtk_mmsys_disconnect() functions to
replace mtk_ddp_add_comp_to_path() and mtk_ddp_remove_comp_from_path().
Those functions will allow DRM driver and others to control the data
path routing.

I think this patch depends on [1] which has been acked by me and I have
not picked it. The simple way is that you pick [1] first and then pick
this series.
