Subject: [PATCH 2/3] drm: fourcc byteorder: add DRM_FORMAT_CPU_*
Date: Tue, 2 May 2017 15:34:03 +0200 [thread overview]
Message-ID: <20170502133404.15354-3-kraxel@redhat.com> (raw)
In-Reply-To: <20170502133404.15354-1-kraxel@redhat.com>
Add fourcc variants in cpu byte order. With these at hand we don't
need #ifdefs in drivers want support framebuffers in cpu endianess.
