Subject: [PATCH 737/806] drm/modes: Parse overscan properties

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.
