The i.MX GPT timer driver binding doc is out of date,
update it according to current GPT timer driver.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

ChangeLog since V3:
	be more specific about the backwards compatible of each SoC;

 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";
 };
