Subject: [PATCH v2 04/15] drm: Add fbconv helper module
Date: Mon, 14 Oct 2019 14:04:05 +0000	[thread overview]
Message-ID: <20191014140416.28517-5-tzimmermann@suse.de> (raw)
In-Reply-To: <20191014140416.28517-1-tzimmermann@suse.de>

This adds fbconv helpers for DRM to the build infrastructure. The
configuration symbol is DRM_FBCONV_HELPERS. Drivers should select
it if they wish to use fbconv.
