+* Device tree bindings for Texas Instruments da8xx system configuration driver
+
+The system configuration (SYSCFG) module is a system-level module containing
+status and top level control logic required by the device. The system
+configuration module consists of a set of memory-mapped status and control
+registers, accessible by the CPU, supporting all of the following system
+features, and miscellaneous functions and operations.
+
+Documentation:
+OMAP-L138 (DA850) - http://www.ti.com/lit/ug/spruh82c/spruh82c.pdf
+
+Required properties:
+
+- compatible:		"ti,da850-syscfg"
+
+Optional properties:
+
+The below properties are used to specify the priority of master peripherals.
+They must be between 0-7 where 0 is the highest priority and 7 is the lowest.
+
+- ti,pri-arm-i:		ARM_I port priority.
+
+- ti,pri-arm-d:		ARM_D port priority.
+
+- ti,pri-upp:		uPP port priority.
+
+- ti,pri-sata:		SATA port priority.
+
+- ti,pri-pru0:		PRU0 port priority.
+
+- ti,pri-pru1:		PRU1 port priority.
+
+- ti,pri-edma30tc0:	EDMA3_0_TC0 port priority.
+
+- ti,pri-edma30tc1:	EDMA3_0_TC1 port priority.
+
+- ti,pri-edma31tc0:	EDMA3_1_TC0 port priority.
+
+- ti,pri-vpif-dma-0:	VPIF DMA0 port priority.
+
+- ti,pri-vpif-dma-1:	VPIF DMA1 port priority.
+
+- ti,pri-emac:		EMAC port priority.
+
+- ti,pri-usb0cfg:	USB0 CFG port priority.
+
+- ti,pri-usb0cdma:	USB0 CDMA port priority.
+
+- ti,pri-uhpi:		HPI port priority.
+
+- ti,pri-usb1:		USB1 port priority.
+
+- ti,pri-lcdc:		LCDC port priority.
+
+If any of the above properties is absent, the default value will be used as
+defined in the documentation.
+
+Example for da850-lcdk is shown below.
+
+mstpri {
+	compatible = "ti,da850-mstpri";
+	ti,pri-lcdc = 0;
+};
