>From all the drivers using drm_bridge_connector only iMX/dcss and OMAP
DRM driver do a proper work of calling
drm_bridge_connector_en/disable_hpd() in right places. Rather than
teaching each and every driver how to properly handle
drm_bridge_connector's HPD, make that automatic.

Add two additional drm_connector helper funcs: enable_hpd() and
disable_hpd(). Make drm_kms_helper_poll_* functions call them (as this
is the time where the drm_bridge_connector's functions are called by the
drivers too).

Dmitry Baryshkov (7):
  drm/poll-helper: merge drm_kms_helper_poll_disable() and _fini()
  drm/probe-helper: enable and disable HPD on connectors
  drm/bridge_connector: rely on drm_kms_helper_poll_* for HPD enablement
  drm/imx/dcss: stop using drm_bridge_connector_en/disable_hpd()
  drm/msm/hdmi: stop using drm_bridge_connector_en/disable_hpd()
  drm/omap: stop using drm_bridge_connector_en/disable_hpd()
  drm/bridge_connector: drop drm_bridge_connector_en/disable_hpd()
