From c58f254be3bd6276133735c8b7762c51589b4d03 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 3 May 2024 15:24:23 +0300 Subject: [PATCH] drm/i915/bios: Define VBT block 3 (Display Toggle Option) contents MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Define the contents of VBT block 3 (Display Toggle Option). On modern VBTs this is just a single byte, but on ALM there is also some extra to do with toggle lists or something.
