Hi Inki,
This is my final fight with DECON_UPDATE issues (I hope). My two previous patches
fixed problems on panel path, this patchset fixes also TV path.
The root cause of all evil was in incorrect DECON_CMU programming.
Now it works correctly on:
- panel,
- TV,
- both.
I have not observed (so far) IOMMU faults, or vblank timeouts.
Regards
Andrzej

decon_commit is called just after reset so video is disabled anyway.

DECON_CMU register has reserved bits which should not be zeroed, otherwise
IP can behave strangely and cause IOMMU faults.

DECON_TV requires STANDALONE_UPDATE after output enabling, otherwise it does
not start. This change is neutral for DECON.
