[PATCH v2 2/2] ARM: dts: sun7i: Add CAN node and can0_pins_a pinctrl settings

[Patrick Menschel]

The A20 SoC has an on-board CAN controller. This patch adds the device node
and the corresponding pinctrl settings for pins PH20 and PH21.

The CAN controller is inherited from the A10 SoC and uses the same driver.

This patch is adapted from the description in
Documentation/devicetree/bindings/net/can/sun4i_can.txt
