NXP I2C controller for LPC2xxx/178x/18xx/43xx
Required properties:
- compatible: must be "nxp,lpc1788-i2c"
- reg: physical address and length of the device registers
- interrupts: a single interrupt specifier
- clocks: clock for the device
- #address-cells: should be <1>
- #size-cells: should be <0>
Optional properties:
- clock-frequency: the desired I2C bus clock frequency in Hz; in
absence of this property the default value is used (100 kHz).
Example:
i2c0: i2c@400a1000 {
compatible = "nxp,lpc1788-i2c";
reg = <0x400a1000 0x1000>;
interrupts = <18>;
clocks = <&ccu1 CLK_APB1_I2C0>;
#address-cells = <1>;
#size-cells = <0>;
};
&i2c0 {
clock-frequency = <400000>;
lm75@48 {
compatible = "nxp,lm75";
reg = <0x48>;
};
};
