Subject: [PATCH 1/3] video: Add 30bpp support
Date: Thu, 16 Sep 2021 15:01:15 +0200	[thread overview]
Message-ID: <20210916130117.20894-2-kettenis@openbsd.org> (raw)
In-Reply-To: <20210916130117.20894-1-kettenis@openbsd.org>

Add support for 30bpp mode where pixels are picked in 32-bit
integers but use 10 bits instead of 8 bits for each component.
