Subject: [PATCH v10 10/23] dt-bindings: reset: Document canaan,k210-rst bindings
Date: Sun, 13 Dec 2020 22:50:43 +0900 [thread overview]
Message-ID: <20201213135056.24446-11-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20201213135056.24446-1-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.
