Subject: [PATCH v5 06/10] media: Add ABGR64_12 video format
Date: Wed, 22 Mar 2023 13:13:09 +0800	[thread overview]
Message-ID: <9c250d2e65405d920d2918521cc86f47c7e78ec3.1679461710.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1679461709.git.ming.qian@nxp.com>

ABGR64_12 is a reversed RGB format with alpha channel last,
12 bits per component like ABGR32,
expanded to 16bits.
Data in the 12 high bits, zeros in the 4 low bits,
arranged in little endian order.
