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>;

	};
