but the changes will hit linux-next at some point and they could be 
tested there, right?

Sorry, as changes for the HDMI drivers go to several maintainers, I was 
trying to send the relevant patches to the respective maintainers and 
avoid potential merge/rebase issues.

Tomi has already taken the DSS changes. Perhaps, if you and Tomi agree, 
Tomi could also take the ASoC and the arch/arm/mach-omap2 changes. This 
way all changes come from the same tree.

I meant that Tomi took the DSS changes in [1] on his master branch and 
he should push them upstream when the merge window for kernel v3.8 opens.
