Subject: drm/i915/vbt: Parse panel options separately from timing data
Git-commit: 9e7ecedf057f4cb7b69b948e90819e129a7fe168
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Newer VBT versions will add an alternate way to read panel DTD
information, so let's split parsing of the general panel information
from the timing data in preparation.
