[PATCH v4 0/3] HS-USB device tree support for R8A7791/Koelsch/Henninger board

[Yoshihiro Shimoda]

   Here's the set of 3 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 R8A7791/Koelsch/Henninger reference boards. 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 v3:
 - rebase the repository.

Yoshihiro Shimoda (3):
  ARM: shmobile: r8a7791: add HS-USB device node
  ARM: shmobile: koelsch: enable HS-USB
  ARM: shmobile: henninger: enable HS-USB

[PATCH v4 1/3] ARM: shmobile: r8a7791: add HS-USB device node

[Yoshihiro Shimoda]

Define the R8A7791 generic part of the HS-USB device node. It is up to the board
file to enable the device.

[PATCH v4 2/3] ARM: shmobile: koelsch: enable HS-USB

[Yoshihiro Shimoda]

Enable HS-USB device for the Koelsch board, defining the GPIO that the driver
should check when probing (which is the ID output from MAX3355 OTG chip).

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.

Enable HS-USB device for the Henninger board, defining the GPIO that the driver
should check when probing (which is the ID output from MAX3355 OTG chip).

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.

Thanks, I have queued these up.
