OK, this applies to for-3.6/common-clk without issue now. However, there
are still runtime problems:

On Tegra20(Ventana), running Tegra's for-next branch with these patches
merged in, if I play audio, the sound is much too low a pitch; the I2S
clock must be being set too low. Also, if I play the same file twice,
once encoded as 48KHz once encoded as 44.1KHz, the pitch is different.

On Tegra20(Ventana), running next-20120703 plus a few local patches for
regulators plus these common clock patches, then I see the same
segfaults during boot that I mentioned before. It seems something in
linux-next not in Tegra's for-next branch is breaking the common clock
code for us.

Neither problem is seen on Cardhu with the same kernels.

Can you please investigate and fix these issues? Thanks.
