Drenesas,iic-emev2.txt1 Device tree configuration for Renesas EMEV2 IIC controller
4 - compatible : "renesas,iic-emev2"
5 - reg : address start and address range size of device
6 - interrupts : specifier for the IIC controller interrupt
7 - clocks : phandle to the IP core SCLK
8 - clock-names : must be "sclk"
9 - #address-cells : should be <1>
10 - #size-cells : should be <0>
15 #address-cells = <1>;
16 #size-cells = <0>;
