1* Texas Instruments Davinci/Keystone I2C2 3This file provides information, what the device node for the4davinci/keystone i2c interface contains.5 6Required properties:7- compatible: "ti,davinci-i2c" or "ti,keystone-i2c";8- reg : Offset and length of the register set for the device9- clocks: I2C functional clock phandle.10 For 66AK2G this property should be set per binding,11 Documentation/devicetree/bindings/clock/ti,sci-clk.yaml12 13SoC-specific Required Properties:14 15The following are mandatory properties for Keystone 2 66AK2G SoCs only:16 17- power-domains: Should contain a phandle to a PM domain provider node18 and an args specifier containing the I2C device id19 value. This property is as per the binding,20 Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml21 22Recommended properties :23- interrupts : standard interrupt property.24- clock-frequency : desired I2C bus clock frequency in Hz.25- ti,has-pfunc: boolean; if defined, it indicates that SoC supports PFUNC26 registers. PFUNC registers allow to switch I2C pins to function as27 GPIOs, so they can be toggled manually.28 29Example (enbw_cmc board):30 i2c@1c22000 {31 compatible = "ti,davinci-i2c";32 reg = <0x22000 0x1000>;33 clock-frequency = <100000>;34 interrupts = <15>;35 interrupt-parent = <&intc>;36 #address-cells = <1>;37 #size-cells = <0>;38 39 dtt@48 {40 compatible = "national,lm75";41 reg = <0x48>;42 };43 };44
