Tegra already supports the common clock framework, but had issues:
1) The clock driver was located in arch/arm/mach-tegra/ rather than
drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.

* [GIT PULL 3/8] ARM: tegra: USB driver cleanup

The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-soc-ccf.

This pull request implements a new "LP2" cpuidle state for Tegra20,
which makes use of the couple cpuidle feature.
It is based on (most of) the previous pull request, with tag

This pull request implements a new "LP2" cpuidle state for Tegra20,
which makes use of the couple cpuidle feature.
It is based on (most of) the previous pull request, with tag
tegra-for-3.9-soc-usb.

Tegra currently relies on the SCU to determine the number of CPU
cores, and also hard-codes the SCU physical address.
This series adds a /cpus node to the Tegra device tree, and updates
the code to rely solely on that to determine the CPU count. A new
API is introduced to query for the existence of SCU registers, and the
SCU register address. Tegra and OMAP2 are converted to use these new
APIs.
This pull request is based on a merge of v3.8-rc3, and arm-soc's
depends/rmk-perf branch.

This one looks like it should also be based on your cleanup, since it has
conflicts with it. Please rebase accordingly.

By the way, just in case this looks like a random request...
A few merge conflicts between independent topic branches is not a big
deal; we can deal with those.
What's somewhat annoying though, is when a previous cleanup branch
conflicts with later features. So, please base features on top of
cleanups accordingly.
Thanks,

Hmm. And here I was thinking that I was basing branches on top of
each-other too much given your previous comments about merge conflicts
being OK!
In case it helps, the following commit in linux-next shows the conflict
resolution:
ee05948 Merge branch 'for-3.9/scu-base-rework' into for-3.9/soc-t114
I guess I missed this because I didn't merge for-3.9/scu-base-rework
into my for-next on its own, but only as part of for-3.9/soc-t114,
within which I had resolved the conflict as above.
So, you could just skip this pull request, and it'll be pulled in when
you merge for-3.9/soc-t114.
It that doesn't work for you, I can do the rebase tomorrow morning.

IMHO the cleanup branches are special in this regard because they
are primarily meant as a way to resolve the merge conflicts.
If you are able to put all the conflicts between the normal branches
into cleanup patches, you can put them all in one branch and
base your other branches on top of that. Of course that doesn't
always work, but it would solve this particular instance.

This pull request adds initial support for the Tegra114 SoC, which
integrates a quad-core ARM Cortex-A15 CPU. I'm proud to observe that we
posted the initial versions of these patches before the final official
announcement of this chip.
These patches are enough to boot with a UART-based console, support the
Dalmore and Pluto reference/evaluation boards, instantiate the GPIO and
pinctrl drivers, and enable a cpuidle state. As yet, no clocks or
storage devices are supported, but patches for those will follow shortly.
This pull request is based on (most of) the previous pull request with
tag tegra-for-3.9-soc-cpuidle, followed by a merge of the previous pull
request with tag tegra-for-3.9-scu-base-rework.

Numerous updates to the various Tegra device trees are made:
* Addition of NVIDIA Beaver (Tegra30) and Toradex Colibri T20 and Iris
carrier boards.
* Enablement of the HDMI connector on most boards.
* Enablement of the keyboard controller on a few boards.
* Addition of the AC'97 controller to Tegra20.
* Addition of a GPIO poweroff node for TrimSlice.
* Changes to support the new "high speed UART" (DMA-capable) driver for
Tegra serial ports, and enablement for Cardhu's UART C.
* A few cleanups, such as compatible flag fixes, node renames, node
ordering fixes, commonizing properties into SoC .dtsi files, etc..
This pull request is based on (most of) the previous pull request with
tag tegra-for-3.9-soc-t114.

Various new features are enabled on Tegra:
* RTC_DRV_TPS6586X to enable the RTC on many boards, such as Harmony
and Ventana.
* POWER_RESET_GPIO to provide a power off driver for TrimSlice.
* Tegra KBC controller support, for Seaboard, Harmony, and Whistler.
* Tegra high-speed UART driver, for Cardhu Bluetooth.
* kexec support.
This pull request is based on v3.8-rc3.

Pulled in 1-4,6-8 (since 6 contains 5 and saved some conflicts).
There were a handful of conflicts during merge, please sanity-check the
contents in arm-soc.
Thanks!

The merges look good, and the resultant arm-soc for-next branch works
fine on Tegra20 at least.
