[PATCH 1/3] dt-bindings: reset: Add devicetree binding for BM1880 reset controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add devicetree binding for Bitmain BM1880 SoC reset controller. This SoC
has two reset controllers each controlling reset lines of different
peripherals.

+Bitmain BM1880 SoC Reset Controller
+===================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible:   Should be "bitmain,bm1880-reset"
+- reg:          Offset and length of reset controller space in SCTRL.
+- #reset-cells: Must be 1.
+
+Example:
+
+        reset: reset-controller@800 {
+                compatible = "bitmain,bm1880-reset";
+                reg = <0x800 0x8>;
+                #reset-cells = <1>;
+        };
