Kernel-4.18.0-80.el8_arm,sp805

ARM AMBA Primecell SP805 Watchdog

Required properties:

  • compatible: Should be “arm,sp805” & “arm,primecell”
  • reg: Should contain location and length for watchdog timer register.
  • interrupts: Should contain the list of watchdog timer interrupts.
  • clocks: clocks driving the watchdog timer hardware. This list should be 2
    clocks. With 2 clocks, the order is wdogclk clock, apb_pclk.

Example:
watchdog@66090000 {
compatible = “arm,sp805”, “arm,primecell”;
reg = <0x66090000 0x1000>;
interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&apb_pclk>,<&apb_pclk>;
clock-names = “wdogclk”, “apb_pclk”;
};
