- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first
- followed by the generic version.
-
-- reg: physical base address and size of the R-Car CAN register map.
-- interrupts: interrupt specifier for the sole interrupt.
-- clocks: phandles and clock specifiers for 3 CAN clock inputs.
-- clock-names: 3 clock input name strings: "clkp1", "clkp2", and "can_clk".
-- pinctrl-0: pin control group to be used for this controller.
-- pinctrl-names: must be "default".

-Required properties for R8A774A1, R8A774B1, R8A774C0, R8A774E1, R8A7795,
-R8A77960, R8A77961, R8A77965, R8A77990, and R8A77995:
-For the denoted SoCs, "clkp2" can be CANFD clock. This is a div6 clock and can
-be used by both CAN and CAN FD controller at the same time. It needs to be
-scaled to maximum frequency if any of these controllers use it. This is done
-using the below properties:
-
-- assigned-clocks: phandle of clkp2(CANFD) clock.
-- assigned-clock-rates: maximum frequency of this clock.
-
-Optional properties:
-- renesas,can-clock-select: R-Car CAN Clock Source Select. Valid values are:
- <0x0> (default) : Peripheral clock (clkp1)
- <0x1> : Peripheral clock (clkp2)
- <0x3> : External input clock
