Subject: [PATCH v7 1/9] media: v4l: Add packed YUV444 24bpp pixel format
Date: Mon, 11 Jan 2021 21:28:14 +0200	[thread overview]
Message-ID: <20210111192822.12178-2-mirela.rabulea@oss.nxp.com> (raw)
In-Reply-To: <20210111192822.12178-1-mirela.rabulea@oss.nxp.com>

From: Mirela Rabulea <mirela.rabulea@nxp.com>

The added format is V4L2_PIX_FMT_YUV24, this is a packed
YUV 4:4:4 format, with 8 bits for each component, 24 bits
per sample.

This format is used by the i.MX 8QuadMax and i.MX 8DualXPlus/8QuadXPlus
JPEG encoder/decoder.
