[PATCH v5 0/2] Add HS-USB device tree support for R8A7790/Lager board

[Yoshihiro Shimoda]

Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20141024-v3.18-rc1' tag. Here we add the HS-USB device tree
support on the R8A7790/Lager reference board. The patchset requires the USB PHY
driver (already merged by Kishon and Greg) and the generic PHY support patches
for the HS-USB driver posted by Yoshihiro Shimoda in order to work...

Changes from v4:
 - rebase the repository.

  ARM: shmobile: r8a7790: add HS-USB device node
  ARM: shmobile: lager: enable HS-USB

[PATCH v5 1/2] ARM: shmobile: r8a7790: add HS-USB device node

[Yoshihiro Shimoda]

Define the R8A7790 generic part of the HS-USB device node.
It is up to the board file to enable the device.

[PATCH v5 2/2] ARM: shmobile: lager: enable HS-USB

[Yoshihiro Shimoda]

Enable HS-USB device for the Lager board, defining the GPIO that the driver
should check when probing. Since this board doesn't have the OTG ID pin, we
assume that GP5_18 (USB0_PWEN) is an ID pin because it is 1 when the SW5 is
in position 2-3 (meaning USB function) and 0 in other positions.

Note that there will be pinctrl-related error messages if both internal PCI
and HS-USB drivers are enabled but they should be just ignored.
