I think there are bugs here. I applied all your clock patches on top of
Tegra's for-next (see list below), and found that the following don't
work on Springbank:

* HDMI display
* Audio playback
* WiFi

I imagine the same issue would be seen on Harmony or Ventana since
they're very similar. All of those functions work fine with Tegra's
for-next branch (commit 5e30b49 "Merge branch 'for-3.9/defconfig' into
for-next").

I didn't try Tegra30. I assume you'll test both SoCs...
