[PATCH 0/7] usb: fotg210: Various improvements

From: Linus Walleij
Date: Tue Jan 03 2023 - 18:35:31 EST


This is some gradual improvements to the FOTG210 dual-mode
USB host/gadget driver.

- Create stricter device tree bindings fixing some mistakes.
We have at least FOTG200 and FOTG210 out there. A third
variant named FUSB220 is probably related but has a separate
driver in the vendor code trees.

- Start to break out common code for remapping of memory and
clock handling to begin with, move this to the core file.

- Check that the block is in the right role before
proceeding, don't abort registration but print a warning
if it's not.

- Assing some default speed and the OF node when the UDC
starts. This is based on the similar pattern in the DW
controllers.

- Implement a proper VBUS session handler calling down to
the hardware VBUS control handler in the Gemini variant.
This makes everything work on my hardware.
