From 3cd15f787b391db5224a27715fe9dc6fc8559bee Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Fri, 3 May 2019 13:58:03 +0100 Subject: [PATCH 612/806] drm: vc4-firmware-kms: Remove incorrect overscan support. The overscan support was required for the old mailbox API in order to match up the cursor and frame buffer planes. With the newer API directly talking to dispmanx there is no difference, therefore FKMS does not need to make any adjustments.
