Subject: [PATCH 1/2] drm/i915/lvds: separate border enable readout from panel fitter
Date: Fri, 29 Apr 2016 15:34:02 +0300 [thread overview]
Message-ID: <1461933243-2140-1-git-send-email-jani.nikula@intel.com> (raw)
The LVDS border enable is independent from the panel fitter. Move the
readout of the "border bits" from i9xx_get_pfit_config() to
intel_lvds_get_config(), where it will be read if LVDS is enabled even
if the panel fitter is not.
This fixes the state checker warning:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in
gmch_pfit.lvds_border_bits (expected 0x00008000, found 0x00000000)
