-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>;
