+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

+- assigned-clocks: phandle of clkp2(CANFD) clock.
+- assigned-clock-rates: maximum frequency of this clock.
