[GIT PULL] Renesas ARM-based SoC: Marzen and r8a7779 for 3.7

[GIT PULL] Renesas ARM-based SoC: Marzen and r8a7779 for 3.7

[Simon Horman]

Hi Olof, Hi Arnd,

please consider the following enhancements to the Marzen board
and r8a7779 SoC by Phil Edworthy, Morimoto-san and myself for 3.7.

* This pull request is based on the usb-next branch of Greg KH's USB tree,
  git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git,
  which is based on v3.6-rc3.

  This is to satisfy compile-time dependencies.
  Please let me know if you would like this handled a different way.

----------------------------------------------------------------
The following changes since commit a7bdf7fa33127bf08eb0810698bca607a9462df4:

[PATCH 03/10] ARM: mach-shmobile: marzen: defconfig update

[Simon Horman]

Update marzen defconfig
* Enable MMC Block device as SDHI hw is now supported.
* Default to NFS root, this is consistent with many other
  shmobile boards
* Enable UNIX which is required by udevd

Other changes are noise due to using make savedefconfig
to create the new defconfig.

[PATCH 05/10] ARM: shmobile: r8a7779: add USB common phy initializer

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

This patch adds common USB phy ports initializer for r8a7779.

The note is that each USB IP have own MSTP clock bit,
and common USB phy port doesn't have MSTP clock,
but this USB phy needs USB clock.
Each USB driver / platform should keep USB MSTP clock somehow.
