   3 This file provides information, what the device node for the
   4 davinci/keystone i2c interface contains.
   5
   6 Required properties:
   7 - compatible: "ti,davinci-i2c" or "ti,keystone-i2c";
   8 - reg : Offset and length of the register set for the device
   9
  10 Recommended properties :
  11 - interrupts : standard interrupt property.
  12 - clock-frequency : desired I2C bus clock frequency in Hz.
  13 - ti,has-pfunc: boolean; if defined, it indicates that SoC supports PFUNC
  14         registers. PFUNC registers allow to switch I2C pins to function as
  15         GPIOs, so they can by toggled manually.

  17 Example (enbw_cmc board):
  18         i2c@1c22000 {
  19                 compatible = "ti,davinci-i2c";
  20                 reg = <0x22000 0x1000>;
  21                 clock-frequency = <100000>;
  22                 interrupts = <15>;
  23                 interrupt-parent = <&intc>;
  24                 #address-cells = <1>;
  25                 #size-cells = <0>;
  26
  27                 dtt@48 {
  28                         compatible = "national,lm75";
  29                         reg = <0x48>;
  30                 };
  31         };
