Jetson thor 的timer只有4个中断吗？GIC_SPI 773是TIM0中断？
tegra264.dtsi中的timer节点的interrupts属性配置了4个中断号，GIC_SPI 773 对应timer0的中断么？776是timer3中断？

	timer@8000000 {
		compatible = "nvidia,tegra234-timer";
		reg = <0x0 0x08000000 0x0 0x00140000>;
		interrupts = <GIC_SPI 773 IRQ_TYPE_LEVEL_HIGH>,
			     <GIC_SPI 774 IRQ_TYPE_LEVEL_HIGH>,
			     <GIC_SPI 775 IRQ_TYPE_LEVEL_HIGH>,
			     <GIC_SPI 776 IRQ_TYPE_LEVEL_HIGH>;
		status = "disabled";
	};

Sorry for the late response.
Is this still an issue to support? Any result can be shared?

我仍然需要帮助，但我没有得到有用的答案。根据TRM，Thor拥有16个 Nv timer，我希望能够使用某个Nv timer，并注册中断，但是内核设备树节点compatible = "nvidia,tegra234-timer";看起来只是一个看门狗驱动？我希望英伟达能提供通用的定时器中断程序

Hi BossOfNvidia,

Are you using the devkit or custom board for Thor?

The node timer@8000000 seems not enabled in your case.

May I know what’s your use case for this?

Do you have custom driver to register the interrupt through request_irq()?
