Subject: [PATCH v2 0/4] Add ext. port vbus handling for onboard-dev

Hi,

this small series is the successor of [1]. The intend of this series is
to make it possible to switch the vbus of the downstream ports of an
onboard-dev hub via ext. regulators controlled via the host.

The approach from v1 was not sufficient since it caused compile errors.
We indentified the issue and went with idea-3 [2] to fix this.

Regards,
  Marco
