Kernel-4.18.0-80.el8_i2c-brcmstb

Broadcom stb bsc iic master controller

Required properties:

• compatible: should be “brcm,brcmstb-i2c” or “brcm,brcmper-i2c”
• clock-frequency: 32-bit decimal value of iic master clock freqency in Hz

       valid values are 375000, 390000, 187500, 200000
       93750, 97500, 46875 and 50000
  

• reg: specifies the base physical address and size of the registers

Optional properties :

• interrupt-parent: specifies the phandle to the parent interrupt controller
  this one is cascaded from
• interrupts: specifies the interrupt number, the irq line to be used
• interrupt-names: Interrupt name string

Example:

bsca: i2c@f0406200 {
clock-frequency = <390000>;
compatible = “brcm,brcmstb-i2c”;
interrupt-parent = <&irq0_intc>;
reg = <0xf0406200 0x58>;
interrupts = <0x18>;
interrupt-names = “upg_bsca”;
};
