Subject: [PATCH v2 02/13] media: v4l: add some definition of v4l2 colorspace/xfer_func/ycbcr_encoding
Date: Mon,  7 Jun 2021 16:42:49 +0800	[thread overview]
Message-ID: <91be725ad5f2f21713aac60a9b5a65f20ef2cd5f.1623054584.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1623054584.git.ming.qian@nxp.com>

Some definition of colorspace/xfer_func/ycbcr_encoding
are defined in ISO, but missed in V4L2,
so add some definition according VPU driver's requirement
