[PATCH] clk: tegra124: Enable hda to hdmi clocks

[Dylan Reid]

Add the clocks used for HDMI audio played through the HDA controller.
Initialize the codec clock to 48Mhz and the HDA clock to 102MHz per
the TRM.

This patch seems fine to me. Peter, I assume you'll apply this and
eventually sent a pull request to Mike.

I guess this is basically needed for Tegra HD-audio HDMI stuff, so I'd
need to pull the change to my branch once when applying other Dylan's
patches.  Let me know the pull-able branch once when merged.
Alternatively, I can apply the all patches in series to my tree if
it's easier, too.  Just let me know what you guys prefer.

(BTW, Dylan, v3 patches haven't been submitted yet, right?)


thanks,

Takashi

This change is only needed at run-time, not at compile-time, so there's
no build-time dependency. Since this is a new feature, it's fine for it
to only work once everything is merged together in linux-next, or
Linus's tree, so there's to push it all through a single branch.

I'll send it out later today, found a runtime pm bug that I want to fix first.

This fix seems still missing in linux-next.  Note that the whole Tegra
HDMI audio driver patches have been already included in for-next
branch of sound git tree.

Thanks for checking Takashi,

I thought it was going through Peter's tree.  Peter have you had a
chance to take a look?

Thanks,

Dylan
