Kernel-4.18.0-80.el8_i2c-img-scb

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>;
};
