Subject: [PATCH v4 0/5] Add onboard-dev USB hub host managed vbus handling
 support

Hi,

the whole purpose of this series is to make it possible to control the
USB VBUS regulators of an USB hub via host managed regulators.

Regards,
  Marco

Changes in v4:
- dt-bindings: change to vbus-supply and shift doc to usb-device.yaml
- onboard_dev: make use of new regulator API to parse child device
               regulators.
- onboard_dev: drop hard coded downstream port number and make it more
               dynamic
- onboard_dev: drop limiting support to SMSC hubs
- Link to v3: https://lore.kernel.org/r/20250821-v6-16-topic-usb-onboard-dev-v3-0-6d2b38a5d818@pengutronix.de

Changes in v3:
- fix dt-bindings issues
- Link to v2: https://lore.kernel.org/all/20250327172803.3404615-1-m.felsch@pengutronix.de/

Changes in v2:
- fix compile time errors in case the module builds
- Link to v1: https://lore.kernel.org/all/20240807-b4-v6-10-topic-usb-onboard-dev-v1-0-f33ce21353c9@pengutronix.de/
