Subject: [PATCH 0/3] Fix DECON_UPDATE for TV

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
