Kernel-4.18.0-80.el8_rtc-mxc

  • Real Time Clock of the i.MX SoCs

RTC controller for the i.MX SoCs

Required properties:

  • compatible: Should be “fsl,imx1-rtc” or “fsl,imx21-rtc”.
  • reg: physical base address of the controller and length of memory mapped
    region.
  • interrupts: IRQ line for the RTC.
  • clocks: should contain two entries:
    • one for the input reference
    • one for the the SoC RTC
  • clock-names: should contain:
    • “ref” for the input reference clock
    • “ipg” for the SoC RTC clock

Example:

rtc@10007000 {
compatible = “fsl,imx21-rtc”;
reg = <0x10007000 0x1000>;
interrupts = <22>;
clocks = <&clks IMX27_CLK_CKIL>,
<&clks IMX27_CLK_RTC_IPG_GATE>;
clock-names = “ref”, “ipg”;
};
