[PATCH v2 0/2] Add R8A7791/Henninger board CAN DT support

[PATCH v2 0/2] Add R8A7791/Henninger board CAN DT support

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-v3.16-rc3-20140701' tag. Here we add the CAN device tree support
for the R8A7791-based Henninger board. It depends on the PFC CAN support and
R-Car CAN device tree support patches posted recently in order to work.

[1/2] ARM: shmobile: r8a7791: add CAN DT support
[2/2] ARM: shmobile: henninger: add CAN0 DT support

WBR, Sergei

[PATCH v2 1/2] ARM: shmobile: r8a7791: add CAN DT support

[Sergei Shtylyov]

Define the generic R8A7791 parts of the CAN0/1 device nodes.

Changes in version 2:
- fixed the "compatible" property in the CAN device nodes.

Thanks, please repost these patches once the bindings have been merged.
