3 Required properties:
4  - compatible: must be "nxp,lpc1788-i2c"
5  - reg: physical address and length of the device registers
6  - interrupts: a single interrupt specifier
7  - clocks: clock for the device
8  - #address-cells: should be <1>
9  - #size-cells: should be <0>

11 Optional properties:
12 - clock-frequency: the desired I2C bus clock frequency in Hz; in
13   absence of this property the default value is used (100 kHz).
