- * Texas Instruments Davinci/Keystone I2C
- 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
- 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 by toggled manually.
- Example (enbw_cmc board):
- i2c@1c22000 {
- compatible = "ti,davinci-i2c";
- reg = <0x22000 0x1000>;
- clock-frequency = <100000>;
- interrupts = <15>;
- interrupt-parent = <&intc>;
- #address-cells = <1>;
- #size-cells = <0>;
- dtt@48 {
- compatible = "national,lm75";
- reg = <0x48>;
- };
- };
