[PATCH v1 0/4] Improve USB FIFO handling and enable UMS mode on PRTT1L boards

[Oleksij Rempel]

This patch series addresses the initial issue of USB Mass Storage (UMS)
mode not working on PRTT1L boards by improving USB FIFO handling in the
DWC2 driver, fixing multiplier handling in endpoint setup, and adding
support for multiple gadgets, including UMS, fastboot, and ACM gadgets.
The changes include porting support for USB FIFO devicetree properties
and FIFO configuration from Linux kernel v6.3. These patches were tested
on a PRTT1C board (based on stm32mp151) with the following command:
usbgadget -S '/dev/mmc1(mmc1)' -s -A '' -b
