Subject: [v6,1/3] dt-binding: reset-controller: mediatek: add YAML schemas
Date: Wed, 30 Sep 2020 10:21:57 +0800	[thread overview]
Message-ID: <20200930022159.5559-2-crystal.guo@mediatek.com> (raw)
In-Reply-To: <20200930022159.5559-1-crystal.guo@mediatek.com>

Add a YAML documentation for Mediatek, which uses ti reset-controller
driver directly. The TI reset controller provides a common reset
management, and is suitable for Mediatek SoCs.
