-Binding for the Cadence I2C controller
-
-Required properties:
- - reg: Physical base address and size of the controller's register area.
- - compatible: Should contain one of:
- * "cdns,i2c-r1p10"
- Note: Use this when cadence i2c controller version 1.0 is used.
- * "cdns,i2c-r1p14"
- Note: Use this when cadence i2c controller version 1.4 is used.
- - clocks: Input clock specifier. Refer to common clock bindings.
- - interrupts: Interrupt specifier. Refer to interrupt bindings.
- - #address-cells: Should be 1.
- - #size-cells: Should be 0.
-
-Optional properties:
- - clock-frequency: Desired operating frequency, in Hz, of the bus.
- - clock-names: Input clock name, should be 'pclk'.
-
-Example:
- i2c@e0004000 {
- compatible = "cdns,i2c-r1p10";
- clocks = <&clkc 38>;
- interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
- reg = <0xe0004000 0x1000>;
- clock-frequency = <400000>;
- #address-cells = <1>;
- #size-cells = <0>;
- };
