Subject: [RFC PATCH v2 6/6] arm64: tegra: Add Tegra VI CSI support in device tree
Date: Wed, 5 Feb 2020 13:23:26 -0800 [thread overview]
Message-ID: <1580937806-17376-7-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1580937806-17376-1-git-send-email-skomatineni@nvidia.com>
Tegra210 contains VI controller for video input capture from MIPI
CSI camera sensors and also supports built-in test pattern generator.
CSI ports can be one-to-one mapped to VI channels for capturing from
an external sensor or from built-in test pattern generator.
This patch adds support for VI and CSI and enables them in Tegra210
device tree.
