1 * NXP PNX I2C Controller 2 3 Required properties: 4 5 - reg: Offset and length of the register set for the device 6 - compatible: should be "nxp,pnx-i2c" 7 - interrupts: configure one interrupt line 8 - #address-cells: always 1 (for i2c addresses) 9 - #size-cells: always 0 10 - interrupt-parent: the phandle for the interrupt controller that 11 services interrupts for this device. 12 13 Optional properties: 14 15 - clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz 16 17 Examples: 18 19 i2c1: i2c@400a0000 { 20 compatible = "nxp,pnx-i2c"; 21 reg = <0x400a0000 0x100>; 22 interrupt-parent = <&mic>; 23 interrupts = <51 0>; 24 #address-cells = <1>; 25 #size-cells = <0>; 26 }; 27 28 i2c2: i2c@400a8000 { 29 compatible = "nxp,pnx-i2c"; 30 reg = <0x400a8000 0x100>; 31 interrupt-parent = <&mic>; 32 interrupts = <50 0>; 33 #address-cells = <1>; 34 #size-cells = <0>; 35 clock-frequency = <100000>; 36 };
