-Device tree configuration for Renesas EMEV2 IIC controller
-
-Required properties:
-- compatible : "renesas,iic-emev2"
-- reg : address start and address range size of device
-- interrupts : specifier for the IIC controller interrupt
-- clocks : phandle to the IP core SCLK
-- clock-names : must be "sclk"
-- #address-cells : should be <1>
-- #size-cells : should be <0>
-
-Example:
-
- iic0: i2c@e0070000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "renesas,iic-emev2";
- reg = <0xe0070000 0x28>;
- interrupts = <0 32 IRQ_TYPE_EDGE_RISING>;
- clocks = <&iic0_sclk>;
- clock-names = "sclk";
- };
