Kernel-4.18.0-80.el8_arm,sp804

ARM sp804 Dual Timers

Required properties:

• compatible: Should be “arm,sp804” & “arm,primecell”
• interrupts: Should contain the list of Dual Timer interrupts. This is the
  interrupt for timer 1 and timer 2. In the case of a single entry, it is
  the combined interrupt or if “arm,sp804-has-irq” is present that
  specifies which timer interrupt is connected.
• reg: Should contain location and length for dual timer register.
• clocks: clocks driving the dual timer hardware. This list should be 1 or 3
  clocks. With 3 clocks, the order is timer0 clock, timer1 clock,
  apb_pclk. A single clock can also be specified if the same clock is
  used for all clock inputs.

Optional properties:

• arm,sp804-has-irq = <#>: In the case of only 1 timer irq line connected, this
  specifies if the irq connection is for timer 1 or timer 2. A value of 1
  or 2 should be used.

Example:

timer0: timer@fc800000 {
    compatible = "arm,sp804", "arm,primecell";
    reg = <0xfc800000 0x1000>;
    interrupts = <0 0 4>, <0 1 4>;
    clocks = <&timclk1 &timclk2 &pclk>;
    clock-names = "timer1", "timer2", "apb_pclk";
};
