Hello.
Here's the set of 3 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20140924-v3.17-rc6' tag. Here we add the USB PHY device tree
support on the R8A7791/Koelsch/Henninger boards. The patchset requires the USB
PHY driver already merged by Kishon and Greg in order to work, so can be
applied at last...
[1/3] ARM: shmobile: r8a7791: add USB PHY DT support
[2/3] ARM: shmobile: koelsch: enable USB PHY
[3/3] ARM: shmobile: henninger: enable USB PHY
WBR, Sergei
Define the R8A7791 generic part of the USB PHY device node. It is up to the
board file to enable the device.

Changes in version 4:
- refreshed the patch.
Changes in version 3:
- changed subnodes of the USB PHY node to be per-channel;
- changed "renesas,phy-select" property to "reg" in the subnodes, and thus added
"#address-cells" and "#size-cells" properties to the parent node;
- moved "#phy-cells" property from the parent node to the subnodes, changing its
value to <1>;
- refreshed the patch.
Changes in version 2:
- added subnodes to the USB PHY node;
- refreshed the patch.
