Subject: [PATCH v6 09/22] dt-bindings: reset: Document canaan,k210-rst bindings
Date: Wed,  9 Dec 2020 14:34:53 +0900	[thread overview]
Message-ID: <20201209053506.122582-10-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20201209053506.122582-1-damien.lemoal@wdc.com>

Document the device tree bindings for the Canaan Kendryte K210 SoC
reset controller driver in
Documentation/devicetree/bindings/reset/canaan,k210-rst.yaml. The header
file include/dt-bindings/reset/k210-rst.h is added to define all
possible reset lines of the SoC.

+  Canaan Kendryte K210 reset controller driver which supports the SoC
+  system controller supplied reset registers for the various peripherals
+  of the SoC. The K210 reset controller node must be defined as a child
+  node of the K210 system controller node.
