+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-rproc"
+ "fsl,imx6sx-rproc"
+- clocks Clock for co-processor (See:
../clock/clock-bindings.txt)
+- syscfg Phandle to syscon block which provide access to
+ System Reset Controller
+
+Optional properties:
+- reg: Should contain the address ranges for some of internal
+ memory regions.
+- reg-names: Contains the corresponding names for the memory
+ regions. These should be named "ddr", "ocram",
"ocram-s",
+ "ocram-epdc" or "ocram-pxp".
+Fallowing memory ranges are expected:
+- For "fsl,imx7d-rproc"
+ <0x00900000 0x00020000> - "ocram"
+ <0x00920000 0x00020000> - "ocram-epdc"
+ <0x00940000 0x00008000> - "ocram-pxp"
+ <0x80000000 0x0FFF0000> - "ddr" (code area)
+ <0x80000000 0x60000000> - "ddr" (data area)
+- For "fsl,imx6sx-rproc"
+ <0x008F8000 0x00004000> - "ocram-s"
+ <0x80000000 0x0FFF8000> - "ddr" (code area)
+ <0x80000000 0x60000000> - "ddr" (data area)
+
+Note: the "ddr" code and data ranges are overlapping. Code area is smaller
+than data area. So this range should be carefully chosen according to your
+system and application requirements.
+
+Example:
+ imx_rproc: imx7d-rp0@0 {
+ compatible = "fsl,imx7d-rproc";
+ reg = <0x80000000 0x80000>, <0x00900000 0x2000>;
+ reg-names = "ddr", "ocram";
+ syscon = <&src>;
+ clocks = <&clks IMX7D_ARM_M4_ROOT_CLK>;
+ };
