Required properties :
- device_type : Should be "i2c"
- 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.
Recommended properties :
- compatible : compatibility list with 2 entries, the first should
be "fsl,CHIP-i2c" where CHIP is the name of a compatible processor,
e.g. mpc8313, mpc8543, mpc8544, mpc5200 or mpc5200b. The second one
should be "fsl-i2c".
- 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
