Subject: [PATCH 01/21] drm/fb-helper: Add fill_info() functions
Date: Tue, 26 Mar 2019 14:19:48 +0100 [thread overview]
Message-ID: <20190326132008.11781-1-daniel.vetter@ffwll.ch> (raw)
The fbdev split between fix and var information is kinda
pointless for drm drivers since everything is fixed: The fbdev
emulation doesn't support changing modes at all.
Create a new simplified helper and use it in the generic fbdev
helper code. Follow-up patches will beef it up more and roll
it out to all drivers.
v2: We need to keep sizes, since they might not match the fb dimesions
(Noralf)
