| I2C for Spreadtrum platforms |
| |
| Required properties: |
| - compatible: Should be "sprd,sc9860-i2c". |
| - reg: Specify the physical base address of the controller and length |
| of memory mapped region. |
| - interrupts: Should contain I2C interrupt. |
| - clock-names: Should contain following entries: |
| "i2c" for I2C clock, |
| "source" for I2C source (parent) clock, |
| "enable" for I2C module enable clock. |
| - clocks: Should contain a clock specifier for each entry in clock-names. |
| - clock-frequency: Contains desired I2C bus clock frequency in Hz. |
| - #address-cells: Should be 1 to describe address cells for I2C device address. |
| - #size-cells: Should be 0 means no size cell for I2C device address. |
| |
| Optional properties: |
| - Child nodes conforming to I2C bus binding |

| Examples: |
| i2c0: i2c@70500000 { |
| compatible = "sprd,sc9860-i2c"; |
| reg = <0 0x70500000 0 0x1000>; |
| interrupts = <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>; |
| clock-names = "i2c", "source", "enable"; |
| clocks = <&clk_i2c3>, <&ext_26m>, <&clk_ap_apb_gates 11>; |
| clock-frequency = <400000>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
