Subject: [PATCH 0/5 v3] adv7511 EDID probing improvements

Hope everyone had a good newyears!

Wanted to re-send out v3 of this patch set improving the EDID
probing on the adv7511 used on HiKey, for consideration for
merging for 4.11

The first three patches are fixups that are hopefully straight
forward, integrating feedback I got from Laurant.

The last two patches try to clean up and resue code, which as
a side effect avoids an issue I'm seeing where something is
going wrong with the regmap cache state for the
ADV7511_REG_EDID_I2C_ADDR(0x43) register which results in
i2c_transfer errors if we don't do the
regcache_sync/_mark_dirty() calls. I suspect there might be a
better solution there, but have not gotten any other suggestions
so I wanted to go ahead and submit these.

Thoughts and feedback would be appreciated!

thanks

New in v3:
* Addressed naming improvements and drm_kms_helper_hotplug_event
  usage corrections as suggested by Laurent.

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

John Stultz (4):
  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
