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: Constains 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>; |
