Can I use the same USB hub schematic from STM32MP1 for STM32MP2?

In STM32MP1, there is an USB hub for 4 USB-A connectors. The hub is Microchip USB2514B. Were 4 means "4 ports".

In STM32MP2, there is an USB too, for 2 USB-A connectors. The hub is Microchip USB2412B. Were 2 means "2 ports".

According to AN5489, it says at 8.13 " Multiple hi-speed USB hosts using an external USB hub component is not described here.". So is that an answer for "yes, it's possible to use USB 2514B with STM32MP2"?

Hi @DMårt ,

I see no blocking point to use whatever embedded HUB (like USB 2514B or else) on STM32MP2 platform, connected to USBH.

Just need to align Device Tree to the right external device in case there is SW configuration needs (e.g. I2C bus, reset signal, etc...).
