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.
- compatible : should be one of following:
for i.MX1:
- "fsl,imx1-gpt";
for i.MX21:
- "fsl,imx21-gpt";
for i.MX27:
- "fsl,imx27-gpt", "fsl,imx21-gpt";
for i.MX31:
- "fsl,imx31-gpt";
for i.MX25:
- "fsl,imx25-gpt", "fsl,imx31-gpt";
for i.MX50:
- "fsl,imx50-gpt", "fsl,imx31-gpt";
for i.MX51:
- "fsl,imx51-gpt", "fsl,imx31-gpt";
for i.MX53:
- "fsl,imx53-gpt", "fsl,imx31-gpt";
for i.MX6Q:
- "fsl,imx6q-gpt", "fsl,imx31-gpt";
for i.MX6DL:
- "fsl,imx6dl-gpt";
for i.MX6SL:
- "fsl,imx6sl-gpt", "fsl,imx6dl-gpt";
for i.MX6SX:
- "fsl,imx6sx-gpt", "fsl,imx6dl-gpt";
- reg : specifies base physical address and size of the registers.
- interrupts : should be the gpt interrupt.
- clocks : the clocks provided by the SoC to drive the timer, must contain
an entry for each entry in clock-names.
- clock-names : must include "ipg" entry first, then "per" entry.
Example:
gpt1: timer@10003000 {
compatible = "fsl,imx27-gpt", "fsl,imx1-gpt";
compatible = "fsl,imx27-gpt", "fsl,imx21-gpt";
reg = <0x10003000 0x1000>;
interrupts = <26>;
clocks = <&clks 46>, <&clks 61>;
clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
<&clks IMX27_CLK_PER1_GATE>;
clock-names = "ipg", "per";
};
