This file provides information, what the device node for the
davinci/keystone i2c interface contains.
Required properties:
- compatible: "ti,davinci-i2c" or "ti,keystone-i2c";
- reg : Offset and length of the register set for the device
- clocks: I2C functional clock phandle.
For 66AK2G this property should be set per binding,
Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
SoC-specific Required Properties:
The following are mandatory properties for Keystone 2 66AK2G SoCs only:
- power-domains: Should contain a phandle to a PM domain provider node
and an args specifier containing the I2C device id
value. This property is as per the binding,
Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
Recommended properties :
- interrupts : standard interrupt property.
- clock-frequency : desired I2C bus clock frequency in Hz.
- ti,has-pfunc: boolean; if defined, it indicates that SoC supports PFUNC
registers. PFUNC registers allow to switch I2C pins to function as
GPIOs, so they can be toggled manually.
