I am just worried if we change the behaviour of using gadget

accepted if we can have some docs, we can implement manually

Peter, correct me if this is wrong. It sounds like you want to have
a way for the user to control which gadget driver gets bound to
which UDC driver when everything is compiled into the kernel,
nothing is built as a separate module. Is that the basic idea?
Yes, I know it can

This patch adds the USB xHCI support for the R-Car H2 and M2 SoCs.
These SoCs use an xHCI but still need specific initialization, mainly
to setup the firmware downloading and the specific registers.
This patch set is based on the usb-next branch of Greg usb.git tree.

Even though usb_functionfs_descs_head structure is now deprecated,
it has been used by some user space tools. Its removel in commit
[ac8dde1: “Add flags to descriptors block”] was an oversight
leading to build breakage for such tools.

It appears that no one ever run ffs-test on a big-endian machine,
since it used cpu-endianess for fs_count and hs_count fields which
should be in little-endian format. Fix by wrapping the numbers in

Ok, so you decided to continue setting mode on every LED brightness

I decided to do it that way because official driver did it as well. I

When disconnecting, it's possible that another thread has already made it
