Freescale i.MX General Purpose Timer (GPT)
Required properties:
- compatible : should be "fsl,<soc>-gpt"
- reg : Specifies base physical address and size of the registers.
- interrupts : A list of 4 interrupts; one per timer channel.
- clocks : The clocks provided by the SoC to drive the timer.
Example:
gpt1: timer@10003000 {
compatible = "fsl,imx27-gpt", "fsl,imx1-gpt";
reg = <0x10003000 0x1000>;
interrupts = <26>;
clocks = <&clks 46>, <&clks 61>;
clock-names = "ipg", "per";
};
