* NXP PNX I2C Controller
|
|
|
|
Required properties:
|
|
|
|
- reg: Offset and length of the register set for the device
|
|
- compatible: should be "nxp,pnx-i2c"
|
|
- interrupts: configure one interrupt line
|
|
- #address-cells: always 1 (for i2c addresses)
|
|
- #size-cells: always 0
|
|
- interrupt-parent: the phandle for the interrupt controller that
|
|
services interrupts for this device.
|
|
|
|
Optional properties:
|
|
|
|
- clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz
|
|
|
|
Examples:
|
|
|
|
i2c1: i2c@400a0000 {
|
|
compatible = "nxp,pnx-i2c";
|
|
reg = <0x400a0000 0x100>;
|
|
interrupt-parent = <&mic>;
|
|
interrupts = <51 0>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
};
|
|
|
|
i2c2: i2c@400a8000 {
|
|
compatible = "nxp,pnx-i2c";
|
|
reg = <0x400a8000 0x100>;
|
|
interrupt-parent = <&mic>;
|
|
interrupts = <50 0>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
clock-frequency = <100000>;
|
|
};
