[PATCH v3 0/3] Add USB PHY device tree support for R8A7791/Koelsch/Henninger board

[Sergei Shtylyov]

Hello.

   Here's the set of 3 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-v3.16-rc5-20140722' tag. Here we add the USB PHY device tree
support on the R8A7791/Koelsch/Henninger boards. The patchset requires the USB
PHY driver (just re-posted) in order to work.

[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

[PATCH v3 1/3] ARM: shmobile: r8a7791: add USB PHY DT support

[Sergei Shtylyov]

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 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.
