+NXP iMX6SX/iMX7D Co-Processor Bindings
+----------------------------------------
+
+This binding provides support for ARM Cortex M4 Co-processor found on some
+NXP iMX SoCs.
+
+Required properties:
+- compatible Should be one of:
+ "fsl,imx7d-cm4"
+ "fsl,imx6sx-cm4"
+- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
+- syscon Phandle to syscon block which provide access to
+ System Reset Controller
+
+Optional properties:
+- memory-region list of phandels to the reserved memory regions.
+ (See: ../reserved-memory/reserved-memory.txt)
+
+Example:
+ m4_reserved_sysmem1: cm4@80000000 {
+ reg = <0x80000000 0x80000>;
+ };
+
+ m4_reserved_sysmem2: cm4@81000000 {
+ reg = <0x81000000 0x80000>;
+ };
+
+ imx7d-cm4 {
+ compatible = "fsl,imx7d-cm4";
+ memory-region = <&m4_reserved_sysmem1>, <&m4_reserved_sysmem2>;
+ syscon = <&src>;
+ clocks = <&clks IMX7D_ARM_M4_ROOT_CLK>;
+ };
