-* I2C
-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible : should be "fsl,CHIP-i2c" where CHIP is the name of a
- compatible processor, e.g. mpc8313, mpc8543, mpc8544, mpc5121,
- mpc5200 or mpc5200b. For the mpc5121, an additional node
- "fsl,mpc5121-i2c-ctrl" is required as shown in the example below.
- - interrupts : <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt. This should be encoded based on
- the information in section 2) depending on the type of interrupt
- controller you have.
-
-Recommended properties :
-
- - fsl,preserve-clocking : boolean; if defined, the clock settings
- from the bootloader are preserved (not touched).
- - clock-frequency : desired I2C bus clock frequency in Hz.
- - fsl,timeout : I2C bus timeout in microseconds.
-
-Examples :
-
- /* MPC5121 based board */
- i2c@1740 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,mpc5121-i2c", "fsl-i2c";
- reg = <0x1740 0x20>;
- interrupts = <11 0x8>;
- interrupt-parent = <&ipic>;
- clock-frequency = <100000>;
- };
-
- i2ccontrol@1760 {
- compatible = "fsl,mpc5121-i2c-ctrl";
- reg = <0x1760 0x8>;

-
- /* MPC5200B based board */
