|
|
|
|
Driver:
|
|
- drivers/i2c/nx_i2c.c
|
|
|
|
Required properties:
|
|
- #address-cells = <1>;
|
|
- #size-cells = <0>;
|
|
- compatible = "nexell,s5pxx18-i2c";
|
|
- reg = <i2c_base 0x100>;
|
|
Where i2c_base has to be the base address of the i2c-register set.
|
|
I2C0: 0xc00a4000
|
|
I2C1: 0xc00a5000
|
|
I2C2: 0xc00a6000
|
|
|
|
Optional properties:
|
|
- clock-frequency: Desired I2C bus frequency in Hz, default value is 100000.
|
|
- i2c-sda-delay-ns (S5P6818 only): SDA delay in ns, default value is 0.
|
|
- Child nodes conforming to i2c bus binding.
|
|
|
|
Example:
|
|
i2c0:i2c@c00a4000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "nexell,s5pxx18-i2c";
|
|
reg = <0xc00a4000 0x100>;
|
|
clock-frequency = <400000>;
|
|
