| 2 | |
| 3 | Required Properties: |
| 4 | - compatible: "img,scb-i2c" |
| 5 | - reg: Physical base address and length of controller registers |
| 6 | - interrupts: Interrupt number used by the controller |
| 7 | - clocks : Should contain a clock specifier for each entry in clock-names |
| 8 | - clock-names : Should contain the following entries: |
| 9 | "scb", for the SCB core clock. |
| 10 | "sys", for the system clock. |
| 11 | - clock-frequency: The I2C bus frequency in Hz |
| 12 | - #address-cells: Should be <1> |
| 13 | - #size-cells: Should be <0> |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | i2c@18100000 { |
| 18 | compatible = "img,scb-i2c"; |
| 19 | reg = <0x18100000 0x200>; |
| 20 | interrupts = <GIC_SHARED 2 IRQ_TYPE_LEVEL_HIGH>; |
| 21 | clocks = <&i2c0_clk>, <&system_clk>; |
| 22 | clock-names = "scb", "sys"; |
| 23 | clock-frequency = <400000>; |
| 24 | #address-cells = <1>; |
| 25 | #size-cells = <0>; |
| 26 | }; |
