+Binding for the i.MX6 EPIT timer
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible: should be "fsl,imx6q-epit"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: Should contain EPIT controller interrupt
+- clocks: list of clock specifiers, must contain an entry for each required
+ entry in clock-names
+- clock-names : as described in the clock bindings
+
+Example:
+ epit1: epit@20d0000 {
+ compatible = "fsl,imx6q-epit";
+ reg = <0x020d0000 0x4000>;
+ interrupts = <0 56 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX6QDL_CLK_EPIT1>,
+ <&clks IMX6QDL_CLK_IPG_PER>,
+ <&clks IMX6QDL_CLK_CKIL>;
+ clock-names = "ipg", "per", "ckil";
+ };
