    Subject[PATCH v3 3/5] arm64: dts: renesas: eagle: Enable MAX9286
    Date
    From: Kieran Bingham <kieran.bingham@ideasonboard.com>

    Enable the MAX9286 GMSL deserializer on the Eagle-V3M board.

    Connected cameras should be defined in a device-tree overlay or included
    after these definitions.
