1Freescale i.MX General Purpose Timer (GPT)
2
3Required properties:
4
5- compatible : should be one of following:
6 for i.MX1:
7 - "fsl,imx1-gpt";
8 for i.MX21:
9 - "fsl,imx21-gpt";
10 for i.MX27:
11 - "fsl,imx27-gpt", "fsl,imx21-gpt";
12 for i.MX31:
13 - "fsl,imx31-gpt";
14 for i.MX25:
15 - "fsl,imx25-gpt", "fsl,imx31-gpt";
16 for i.MX50:
17 - "fsl,imx50-gpt", "fsl,imx31-gpt";
18 for i.MX51:
19 - "fsl,imx51-gpt", "fsl,imx31-gpt";
20 for i.MX53:
21 - "fsl,imx53-gpt", "fsl,imx31-gpt";
22 for i.MX6Q:
23 - "fsl,imx6q-gpt", "fsl,imx31-gpt";
24 for i.MX6DL:
25 - "fsl,imx6dl-gpt";
26 for i.MX6SL:
27 - "fsl,imx6sl-gpt", "fsl,imx6dl-gpt";
28 for i.MX6SX:
29 - "fsl,imx6sx-gpt", "fsl,imx6dl-gpt";
30- reg : specifies base physical address and size of the registers.
31- interrupts : should be the gpt interrupt.
32- clocks : the clocks provided by the SoC to drive the timer, must contain
33 an entry for each entry in clock-names.
34- clock-names : must include "ipg" entry first, then "per" entry.

36Example:
37
38gpt1: timer@10003000 {
39 compatible = "fsl,imx27-gpt", "fsl,imx21-gpt";
40 reg = <0x10003000 0x1000>;
41 interrupts = <26>;
42 clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
43 <&clks IMX27_CLK_PER1_GATE>;
44 clock-names = "ipg", "per";
45};
