All of the in-tree device-trees that use the one of the compatible strings from i2c-mpc.c supply an interrupts property. Make this property mandatory to aid refactoring the driver.

For the mpc5121, an additional node "fsl,mpc5121-i2c-ctrl" is required as shown in the example below. - -Recommended properties : - - 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.
