Merge branch 'for-3.5/usb-ulpi' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/drivers

By Stephen Warren (30) and others
via Stephen Warren
* 'for-3.5/usb-ulpi' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: (7 commits)
  ARM: dt: tegra: pinmux changes for USB ULPI
  ARM: tegra: add USB ULPI PHY reset GPIO to device tree
  ARM: tegra: don't hard-code USB ULPI PHY reset_gpio
  ARM: tegra: change pll_p_out4's rate to 24MHz
  ARM: tegra: fix pclk rate
  ARM: tegra: reparent sclk to pll_c_out1
  ARM: tegra: Add pllc clock init table
  + depends/pinctrl/mergebase branch

Pinctrl mergebase has a conflict in drivers/pinctrl/core.c that was resolved.
