[PATCH 0/8] Add CAN support to iwg2[02]d

[PATCH 0/8] Add CAN support to iwg2[02]d

[Fabrizio Castro]

Hello,

this series delivers all of the changes necessary to add CAN bus
support to the:
* iW-RainboW-G22D SODIMM, and
* iW-RainboW-G20M-Qseven-RZG1M
development platforms, including documentation, pinctrl driver, SoC
specific device trees, and board specific device trees.

This work has been based and tested on top of:
renesas-devel-20171106-v4.14-rc8

Best regards,

Fabrizio Castro (8):

[PATCH 1/8] dt-bindings: can: rcar_can: document r8a774[35] can support

[Fabrizio Castro]

Document "renesas,can-r8a7743" and "renesas,can-r8a7745" compatible
strings. Since the fallback compatible string ("renesas,rcar-gen2-can")
activates the right code in the driver, no driver change is needed.

Thanks, I have applied the "ARM: dts" patches for inclusion in v4.16.
