This patchset does following:
1. Decompose single tegra clock structure into multiple clocks.
2. Try to use standard clock types supported by common clock
framework.
3. Use dynamic initialization.
4. Move all clock code to drivers/clk/tegra from mach-tegra.
5. Add device tree support for Tegra20 and Tegra30 clocks.
6. Remove all legacy clock code from mach-tegra.

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

(BTW, I stopped Cc'ing linux-kernel@, but added linux-tegra@
instead...)

Prashant, some updated testing results based off the "dev/ccf" branch
you sent me on our internal git server:

I have updated the internal branch with all the above mentioned fixes.

The remaining item is the display issue on Tegra30, which I'll go look
at now.

The USB3 clock, which isn't used by any drivers on Tegra30, and hence
was disabled at boot, was set up incorrectly and ended up mapping to the
disp1 clock, and hence turned off the display. The following fixes it:

Stephen, thanks for the fix!! I have included this and PLLE fix; updated
internal branch.

Almost everything works great now.

Great!!

However, I don't see any fix for the PLLE issue in the code; if there is
one it certainly doesn't work. Applying my previous hack makes it work.

There is some difference between Tegra20 and Tegra30 PLLE implementation.
Fixed in latest patches sent.

FYI, the branch I tested with is at
git://nv-tegra.nvidia.com/user/swarren/linux-2.6 test-ccf-rework-2

It's rebased onto the latest Tegra for-next.
