1* Texas Instruments Davinci/Keystone I2C
2
3This file provides information, what the device node for the
4davinci/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 device
9- clocks: I2C functional clock phandle.
10	  For 66AK2G this property should be set per binding,
11	  Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
12
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 node
18			and an args specifier containing the I2C device id
19			value. This property is as per the binding,
20			Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
21
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 PFUNC
26	registers. PFUNC registers allow to switch I2C pins to function as
27	GPIOs, so they can be toggled manually.

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	};
