I believe that means adding .atomic_{enable,disable} callbacks to the display-connector bridge (drivers/gpu/drm/bridge/display-connector.c) which would enable/disable the regulator. Unless it messes up with e.g. cable detection (which I believe requires the regulator to be enabled), in that case unconditionally enable it in the connector's probe function. >> + >> + ports: >> + $ref: /schemas/graph.yaml#/properties/ports > > You need to define what each 'port' node is.
