Subject: [PATCH v2 1/3] dt-bindings: media: document the nxp,imx8mq-mipi-csi2 receiver phy and controller
Date: Mon, 31 May 2021 13:23:24 +0200 [thread overview]
Message-ID: <20210531112326.90094-2-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20210531112326.90094-1-martin.kepplinger@puri.sm>
The i.MX8MQ SoC integrates a different MIPI CSI receiver as the i.MX8MM so
describe the DT bindings for it.
