[PATCH 0/3] Add support for USB onboard HUB, used on stm32 boards

[Fabrice Gasnier]

This series adds a driver to support USB onboard HUB, inspired by Linux
onboard hub driver.

Purpose is to manage the power supply regulator on STM32 boards, for
low power use case in Linux. U-boot driver allows to benefit of the
device tree part to supply the HUB when need, instead using an
always-on regulator.

It aligns the relevant DT part from emerging Linux v6.2. It also adds the
relevant default configuration on stm32mp15.
