| 2 | |
| 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> |
| 10 | |
| 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). |
| 14 | |
| 15 | Example: |
| 16 | i2c0: i2c@400a1000 { |
| 17 | compatible = "nxp,lpc1788-i2c"; |
| 18 | reg = <0x400a1000 0x1000>; |
| 19 | interrupts = <18>; |
| 20 | clocks = <&ccu1 CLK_APB1_I2C0>; |
| 21 | #address-cells = <1>; |
| 22 | #size-cells = <0>; |
| 23 | }; |
| 24 | |
| 25 | &i2c0 { |
| 26 | clock-frequency = <400000>; |
| 27 | |
| 28 | lm75@48 { |
| 29 | compatible = "nxp,lm75"; |
| 30 | reg = <0x48>; |
| 31 | }; |
| 32 | }; |
