Merge branch 'for-3.6/common-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/clk

Browse source 
From Stephen Warren <[email protected]>:

This branch contains numerous changes required as a baseline in order to
convert Tegra to the common clock framework. The intention was to also
include patches to actually convert Tegra to the common clock framework.
However, those patches appeared late in the kernel cycle and currently
cause regressions on some boards, so were dropped for now.

* 'for-3.6/common-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: tegra: Provide clock for only one PWM controller
  ARM: tegra: Fix PWM clock programming
  ARM: tegra: dma: rename driver name for clock to "tegra-apbdma"
  ARM: tegra: Remove second instance of uart clk
  crypto: add clk_prepare/clk_unprepare
  ASoC: tegra: add clk_prepare/clk_unprepare
  staging: nvec: add clk_prepare/clk_unprepare
  spi/tegra: add clk_prepare/clk_unprepare
  Input: tegra-kbc - add clk_prepare/clk_unprepare
  USB: ehci-tegra: add clk_prepare/clk_unprepare
  mmc: tegra: add clk_prepare/clk_unprepare
  i2c: tegra: Add clk_prepare/clk_unprepare
  ARM: tegra: add clk_prepare/clk_unprepare
