I certainly tested my patch set on multiple i.MX6 platforms, so, the build
is ok in my side.

Nope, the flag is host_req_flag, not "host_request_flag" as you said,
See my patch 3/7:

I don't know why you has this build issue, I created my patchset against
Peter's chipidea tree(ci-for-usb-next branch). I will apply my patches
to your tree(testing_next) and try again.
