[PATCH v2 0/2] Add USB PHY device tree support for R8A7794/SILK board

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo's
'renesas-devel-20151001-v4.3-rc3' tag. Here we add the USB PHY device tree
support on the R8A7794/SILK low cost board.

[1/2] ARM: shmobile: r8a7794: add USB PHY DT support
[2/2] ARM: shmobile: silk: enable USB PHY

WBR, Sergei

[PATCH v2 1/2] ARM: shmobile: r8a7794: add USB PHY DT support

[Sergei Shtylyov]

Define the R8A7794 generic part of the USB PHY device node. It is up to the
board file to enable the device.
