IMG Serial Control Bus (SCB) I2C Controller
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
- compatible: "img,scb-i2c"
|
||
|
|
- reg: Physical base address and length of controller registers
|
||
|
|
- interrupts: Interrupt number used by the controller
|
||
|
|
- clocks : Should contain a clock specifier for each entry in clock-names
|
||
|
|
- clock-names : Should contain the following entries:
|
||
|
|
"scb", for the SCB core clock.
|
||
|
|
"sys", for the system clock.
|
||
|
|
- clock-frequency: The I2C bus frequency in Hz
|
||
|
|
- #address-cells: Should be <1>
|
||
|
|
- #size-cells: Should be <0>
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
i2c@18100000 {
|
||
|
|
compatible = "img,scb-i2c";
|
||
|
|
reg = <0x18100000 0x200>;
|
||
|
|
interrupts = <GIC_SHARED 2 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
clocks = <&i2c0_clk>, <&system_clk>;
|
||
|
|
clock-names = "scb", "sys";
|
||
|
|
clock-frequency = <400000>;
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
};
