Subject: [PATCH v6 6/8] arm64: dts: renesas: eagle: Enable MAX9286
Date: Thu, 22 Jul 2021 11:12:37 +0200	[thread overview]
Message-ID: <20210722091239.26451-7-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20210722091239.26451-1-jacopo+renesas@jmondi.org>

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.
