Subject: [PATCH] arm64: dts: renesas: r8a774c0-cat874: Add support for AISTARVISION MIPI Adapter V2.1
Date:   Fri, 28 Feb 2020 17:02:10 +0000
Message-Id: <20200228170210.18252-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

Precedence: bulk

This patch adds support AISTARVISION MIPI Adapter V2.1 board connected
to G2E board. Common file aistarvision-mipi-adapter-2.1.dtsi is created
which have the camera endpoint nodes with disabled status and in
r8a774c0-ek874-mipi-2.1.dts file VIN/CSI nodes are enabled. By default
imx219 endpoint is tied with CSI2.

Geert/Rob since the imx219 driver is yet to make into mainline
but has been merged into media-subsystem I would like to take
this patch via media-tree.
