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";

+- 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";

- clocks = <&clks 46>, <&clks 61>;
+ clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
+ <&clks IMX27_CLK_PER1_GATE>;
clock-names = "ipg", "per";
