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.
