From Stephen Warren <swarren@wwwdotorg.org>:

ARM: tegra: clock driver development

This branch contains most fixes and enhancements to the Tegra common
clock driver. The main new feature is a driver for Tegra114, which
coupled with later device tree changes enables many devices on that
chip, such as MMC, I2C, etc.

This branch depends on a patch in:

git://git.linaro.org/people/mturquette/linux.git clk-for-3.10

Mike has stated that this branch is stable, and is aware of this
dependency and merge.

Mike's branch is based on v3.9-rc3, which includes a USB change which
causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
this branch pulls in v3.9-rc4 to ensure bisectability as much as
possible.

This branch is based on v3.9-rc4, followed by a merge of previous Tegra
"soc" pull request, followed by a merge of clk-for-3.10.

Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>:

This series consists mainly of clean-ups for clockevents and

This patch adds a arm-pmu node to bind device tree for exynos4210.
The exynos4210 and 4212 have two cpus which includes a pmu. In contrast, the
exynos4412 has 4 cpus and pmus. We need to define two more pmus for this type
board. However, supporting arm-pmu for the exynos4412 will handle it later

This patch defines irq numbers of ARM performance monitoring unit for exynos4.
Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization
of exynos from plat-samsung for easily defining it.

The number of CPU cores and PMU irq numbers are vary according to soc types.
So, we need to identify each soc type using soc_is_xxx function and to define
the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.

Refactor the PLL programming code to make it useable by the new PLL types
introduced by Tegra114.

The following changes were done:

* Split programming the PLL into updating m,n,p and updating cpcon
* Move locking from _update_pll_cpcon() to clk_pll_set_rate()
* Introduce _get_pll_mnp() helper
* Move check for identical m,n,p values to clk_pll_set_rate()
* struct tegra_clk_pll_freq_table will always contain the values as defined
  by the hardware.
* Simplify the arguments to clk_pll_wait_for_lock()
* Split _tegra_clk_register_pll()

tegra_boot_secondary() relies on some of the car ops. This means having an
uninitialized tegra_cpu_car_ops will lead to an early boot panic.
Providing a dummy struct avoids this and makes adding Tegra114 clock support
in a bisectable way a lot easier.
