-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>;
-       };
