Subject: [PATCH 25/30] v4l: videodev2: Add 10bit definitions for NV12 and NV16 color formats
Date:   Wed, 18 Aug 2021 19:40:32 +0530
Message-Id: <20210818141037.19990-26-sidraya.bj@pathpartnertech.com>

Precedence: bulk

From: Sidraya <sidraya.bj@pathpartnertech.com>

The default color formats support only 8bit color depth. This patch
adds 10bit definitions for NV12 and NV16.
