- pinctrl-0: pin control group to be used for this controller.

Required properties for "renesas,can-r8a7795" compatible:

In R8A7795 SoC, "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)
