Subject: [RESEND PATCH v2 0/2] Check MST topology change on resume
Date: Tue, 23 Oct 2018 19:19:23 -0700	[thread overview]
Message-ID: <20181024021925.27026-1-juston.li@intel.com> (raw)

Updated and resending these patches from Lyude:
https://lkml.org/lkml/2016/5/19/361
https://lkml.org/lkml/2016/5/19/360

As Lyude explains in patch 1/2, we can't rely on MST hubs to handle
hotplugs during suspend. This patchset will check if any EDID's changed
upon resume and reset the MST connections if they did.

This resolves issues with monitors not being detected when hotplugging them
during suspend.

Signed-off-by: Juston Li <juston.li@intel.com>

Changes since v1:
 - update functions that have been renamed since the original patch
 - add a null check for the cached EDID in case a new device was added
 - checkpatch fixes

Lyude (2):
  drm/dp/mst: Reprobe EDID for MST ports on resume
  drm/i915/mst: Reset MST after resume when necessary
