Kernel-4.18.0-80.el8_img,pistachio-gptimer

• Pistachio general-purpose timer based clocksource

Required properties:

• compatible: “img,pistachio-gptimer”.
• reg: Address range of the timer registers.
• interrupts: An interrupt for each of the four timers
• clocks: Should contain a clock specifier for each entry in clock-names
• clock-names: Should contain the following entries:

           "sys", interface clock
           "slow", slow counter clock
           "fast", fast counter clock
  

• img,cr-periph: Must contain a phandle to the peripheral control

     syscon node.
  

Example:
timer: timer@18102000 {
compatible = “img,pistachio-gptimer”;
reg = <0x18102000 0x100>;
interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
<&clk_periph PERIPH_CLK_COUNTER_SLOW>,
<&cr_periph SYS_CLK_TIMER>;
clock-names = “fast”, “slow”, “sys”;
img,cr-periph = <&cr_periph>;
};
