[PATCH v6 0/3] usb: misc: onboard_usb_hub: add support for Cypress HX3 USB 3.0 family

From: Benjamin Bara
Date: Fri Jun 23 2023 - 02:20:59 EST


Hi!

This series adds support for the Cypress HX3 USB 3.0 family (2/3). For
now, it just contains the USB-related aspects and ignores the option to
connect it via i2c (3/3).

As the HX3 family operates with two power supplies, multiple power
supply support is implemented (1/3).

Thanks & best regards,
Benjamin
