It is a simple down-counter timer used mainly as the kernel tick source. The PIT is clocked from the slow clock and shares a single IRQ line with other System Controller peripherals. properties: compatible: const: atmel,at91sam9260-pit reg: maxItems: 1 interrupts: maxItems: 1 clocks: maxItems: 1 required: - compatible - reg - interrupts unevaluatedProperties: false examples: - | #include timer@fffffd30 { compatible = "atmel,at91sam9260-pit"; reg = <0xfffffd30 0x10>; interrupts = <1 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clk32k>; }; ...
