On some devices the 5V pin of the HDMI connector and/or the ESD
protection logic is powered on by a separate regulator. The dp-connector
for such usecases provides dp-pwr supply support. Follow this example
and make hdmi-connector support the hdmi-pwr supply.

Dmitry Baryshkov (3):
  dt-bindings: display: hdmi-connector: add hdmi-pwr supply
  drm/bridge: display-connector: rename dp_pwr to connector_pwr
  drm/bridge: display-connector: handle hdmi-pwr supply
