Subject: [PATCH 0/6 v4] adv7511 EDID probing improvements

Wanted to re-send out v4  of this patch set, integrating some
changes suggested by Laurent, for consideration for merging for
v4.11

The first three patches are fixups that are hopefully straight
forward, integrating feedback I got from Laurant, with minimal
change from the previous versions.

The last three patches try to clean up and rework the EDID
probing code, to avoid issues seen on HiKey. I've reworked these
more significantly since v3 to address feedback from Laurent.

Thoughts and feedback would be appreciated!

thanks
-john

New in v4:
* Tweaked connector.status assignment to avoid race, as
  suggested by Laurent
* Reworked the __adv7511_power_on helpers to avoid calling
  regcache_sync in the EDID probe path
* Added new patch to set EDID_I2C_ADDR register before doing
  EDID read.

Archit Taneja (1):
  drm/bridge: adv7511: Enable HPD interrupts to support hotplug and
    improve monitor detection

John Stultz (5):
  drm/bridge: adv7511: Use work_struct to defer hotplug handing to out
    of irq context
  drm/bridge: adv7511: Switch to using drm_kms_helper_hotplug_event()
  drm/bridge: adv7511: Rework adv7511_power_on/off() so they can be
    reused internally
  drm/bridge: adv7511: Reuse __adv7511_power_on/off() when probing EDID
  drm/bridge: adv7511: Re-write the i2c address before EDID probing
