Subject: [Intel-gfx] [PATCH 3/3] drm/i915: move gmbus restore to i915_restore_display
Date: Thu, 10 Sep 2020 12:52:27 +0300	[thread overview]
Message-ID: <20200910095227.9466-3-jani.nikula@intel.com> (raw)
In-Reply-To: <20200910095227.9466-1-jani.nikula@intel.com>

Logically part of the display restore.

Note: This has been in place since the introduction of gmbus
support. The gmbus code also does the resets before transfers. Is this
really needed, or a historical accident?
