[PATCH v2 1/4] dt-bindings: reset: Add devicetree binding for BM1880 reset controller
From: Manivannan Sadhasivam
Date: Wed May 08 2019 - 12:54:41 EST
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>;
+ };
