Subject: [RFT PATCH 2/4] usb: dwc2: Turn on uframe_sched on "his" platforms
Date: Fri,  6 Jul 2018 09:21:52 -0700	[thread overview]
Message-ID: <20180706162154.196345-3-dianders@chromium.org> (raw)
In-Reply-To: <20180706162154.196345-1-dianders@chromium.org>

There's no reason to have the uframe scheduler off on dwc2.  Running
with uframe_sched = False is equivalent to saying "I don't want to run
the correct code, I want to run the old and incorrect code".

The uframe scheduler has been off on HiSilicon since commit
37dd9d65cc41 ("usb: dwc2: add support of hi6220").  Since then there
have been many many improvements, notably the commit 9f9f09b048f5
("usb: dwc2: host: Totally redo the microframe scheduler")

Presumably if everyone is good w/ the uframe_sched turned back on we
can kill all the old and crufty non-uframe sched code.
