Kernel-4.18.0-80.el8_i2c-mxs

• Freescale MXS Inter IC (I2C) Controller

Required properties:

• compatible: Should be “fsl,-i2c”
• reg: Should contain registers location and length
• interrupts: Should contain ERROR interrupt number
• clock-frequency: Desired I2C bus clock frequency in Hz.

               Only 100000Hz and 400000Hz modes are supported.
  

• dmas: DMA specifier, consisting of a phandle to DMA controller node
  and I2C DMA channel ID.
  Refer to dma.txt and fsl-mxs-dma.txt for details.
• dma-names: Must be “rx-tx”.

Examples:

i2c0: i2c@80058000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = “fsl,imx28-i2c”;
reg = <0x80058000 2000>;
interrupts = <111>;
clock-frequency = <100000>;
dmas = <&dma_apbx 6>;
dma-names = “rx-tx”;
};
