Subject: [PATCH v3 0/3] drm/bridge: display-connector: add external supply support
Date: Wed, 31 May 2023 03:02:56 +0300 [thread overview]
Message-ID: <20230531000259.3758235-1-dmitry.baryshkov@linaro.org> (raw)
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
