-Amlogic Meson6 SoCs Timer Controller
-
-Required properties:
-
-- compatible : should be "amlogic,meson6-timer"
-- reg : Specifies base physical address and size of the registers.
-- interrupts : The four interrupts, one for each timer event
-- clocks : phandles to the pclk (system clock) and XTAL clocks
-- clock-names : must contain "pclk" and "xtal"
-
-Example:
-
-timer@c1109940 {
- compatible = "amlogic,meson6-timer";
- reg = <0xc1109940 0x14>;
- interrupts = <GIC_SPI 10 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 11 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 6 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 29 IRQ_TYPE_EDGE_RISING>;
- clocks = <&xtal>, <&clk81>;
- clock-names = "xtal", "pclk";
-};
