Subject: [PATCH 748/826] 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.
