Subject: [PATCH 0/3] usb: host: fotg210: fix malfunctions in usb camera scenario

Hi :-)

Currently, I tried to support usb camera on the fotg210 host
controller but came across a few issues, for example system
crash, video streaming error, etc. As fotg210 is an ehci-like
controller, I borrowed some ideas from the ehci-hcd driver,
and at least the usb camera can work now.

By the way, the fotg210-hcd driver seems a bit out of date,
is there any plan to update it based on the latest ehci-hcd
driver?

Thank you!
