Subject: [PATCH v2 02/10] drm/fourcc: Add drm_format_info.is_color_indexed flag
Date: Mon, 7 Mar 2022 21:52:37 +0100 [thread overview]
Message-ID: <c0a11d8203d58dbaa5f22479c48504dabdd9b4e1.1646683502.git.geert@linux-m68k.org> (raw)
In-Reply-To: <cover.1646683502.git.geert@linux-m68k.org>
Add a flag to struct drm_format_info to indicate if a format is
color-indexed, similar to the existing .is_yuv flag.
This way generic code and drivers can just check this flag, instead of
checking against a list of fourcc formats.
