+Subject: [PATCH 738/773] drm/modes: Parse overscan properties
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit 3d46a3007cd8f73bae502bf5c171977b91d7aacc upstream.
+
+Properly configuring the overscan properties might be needed for the
+initial setup of the framebuffer for display that still have overscan.
+Let's allow for more properties on the kernel command line to setup each
+margin.
