+* Device tree bindings for Texas Instruments da8xx master peripheral
+ priority driver
+
+DA8XX SoCs feature a set of registers allowing to change the priority of all
+peripherals classified as masters.
+
+Documentation:
+OMAP-L138 (DA850) - http://www.ti.com/lit/ug/spruh82c/spruh82c.pdf
+
+Required properties:
+
+- compatible: "ti,da850-mstpri" - for da850 based boards
+- reg: offset and length of the mstpri registers
+
+Example for da850-lcdk is shown below.
+
+mstpri {
+ compatible = "ti,da850-mstpri";
+ reg = <0x14110 0x0c>;
+};
