[PATCH v3 0/3] drm/bridge: display-connector: add external supply support

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.

Changes since v2:
- Changed to use proper supply name instead of hardcoded "dp-pwr" (Neil)

Changes since v1:
- Changed the pin description to HDMI +5V Power
- Renamed 'connector_pwr' to simpler 'supply'
- Extracted the common supply-handling code for DP and HDMI

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
