Subject: [PATCH v3 0/1] drm/bridge: ps8640: Make sure all needed is powered to get the EDID

The first 4 patches of the series version 2:
  - drm/bridge_connector: Set default status connected for eDP connectors
  - drm/bridge: ps8640: Get the EDID from eDP control
  - drm/bridge: ps8640: Return an error for incorrect attach flags
  - drm/bridge: ps8640: Print an error if VDO control fails

Are already applied to drm-misc-next, so I removed from this series. The
pending patch is part of the original series and is a rework of the power
handling to get the EDID. Basically, we need to make sure all the
needed is powered to be able to get the EDID. Before, we saw that getting
the EDID failed as explained in the third patch.
