| 2 | |
| 3 | Required properties: |
| 4 | - compatible: should be "socionext,uniphier-i2c". |
| 5 | - #address-cells: should be 1. |
| 6 | - #size-cells: should be 0. |
| 7 | - reg: offset and length of the register set for the device. |
| 8 | - interrupts: a single interrupt specifier. |
| 9 | - clocks: phandle to the input clock. |
| 10 | |
| 11 | Optional properties: |
| 12 | - clock-frequency: desired I2C bus frequency in Hz. The maximum supported |
| 13 | value is 400000. Defaults to 100000 if not specified. |
| 14 | |
| 15 | Examples: |
| 16 | |
| 17 | i2c0: i2c@58400000 { |
| 18 | compatible = "socionext,uniphier-i2c"; |
| 19 | reg = <0x58400000 0x40>; |
| 20 | #address-cells = <1>; |
| 21 | #size-cells = <0>; |
| 22 | interrupts = <0 41 1>; |
| 23 | clocks = <&i2c_clk>; |
| 24 | clock-frequency = <100000>; |
| 25 | }; |
