Subject: [PATCH v12 1/6] dt-bindings: media: add pclk-sample dual edge property
Date: Tue, 3 Mar 2020 13:27:17 +0800 [thread overview]
Message-ID: <20200303052722.94795-2-jitao.shi@mediatek.com> (raw)
In-Reply-To: <20200303052722.94795-1-jitao.shi@mediatek.com>
Some chips's sample mode are rising, falling and dual edge (both
falling and rising edge).
Extern the pclk-sample property to support dual edge.
