Subject: [PATCH v4 04/13] media: tegra-video: Add support for V4L2_PIX_FMT_NV16
Date: Fri, 11 Dec 2020 09:02:33 -0800 [thread overview]
Message-ID: <1607706162-1548-5-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1607706162-1548-1-git-send-email-skomatineni@nvidia.com>
NV16 are two-plane versions of YUV422 format.
VI/CSI surface0 registers corresponds to first Y plane and
surface1 registers corresponds to seconds UV plane.
This patch updates image size for NV16 format to include both planes
and programs VI/CSI surface1 registers for UV plane capture.
