[PATCH 2/2] ARM: dts: vf-colibri: add CAN support

Stefan Agner stefan at agner.ch
Wed Dec 2 14:11:47 PST 2015


Add Colibri standard pinmux for FlexCAN controller instances. CAN
is not a standard Colibri feature, but the datasheet predefines
pins which provide CAN (compatible across some modules). Hence,
add the pinmux on module level.
