+Binding for the i.MX Enhanced Periodic Interrupt Timer (EPIT)
+
+The Enhanced Periodic Interrupt Timer (EPIT) is a 32-bit set-and-forget timer
+that is capable of providing precise interrupts at regular intervals with
+minimal processor intervention.
+
+Required properties:
+- compatible: should be "fsl,<chip>-epit", "fsl,imx31-epit" where <chip> is
+ imx25, imx6qdl, imx6sl, imx6sul or imx6sx.
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: Should contain EPIT controller interrupt
+- clocks : The clock provided by the SoC to drive the timer.
+
+Example for i.MX6QDL:
+ epit1: epit@20d0000 {
+ compatible = "fsl,imx6qdl-epit", "fsl,imx31-epit";
+ reg = <0x020d0000 0x4000>;
+ interrupts = <0 56 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX6QDL_CLK_EPIT1>;
+ };
