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.

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.
