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 | }; |
