Subject: [PATCH v4 11/13] dt-bindings: tegra: Update csi data-lanes to maximum 8 lanes
Date: Fri, 11 Dec 2020 09:02:40 -0800 [thread overview]
Message-ID: <1607706162-1548-12-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1607706162-1548-1-git-send-email-skomatineni@nvidia.com>
Tegra VI/CSI hardware don't have native 8 lane CSI RX port.
But x8 capture can be supported by using consecutive x4 ports
simultaneously with HDMI-to-CSI bridges where source image is split
on to two x4 ports.
This patch updates dt-bindings for csi endpoint data-lane property
with maximum of 8 lanes.
