Subject: [PATCH RESEND] usb: musb: Fix suspend with devices connected for a64
Date: Wed, 24 Mar 2021 09:11:41 +0200 [thread overview]
Message-ID: <20210324071142.42264-1-tony@atomide.com> (raw)
Pinephone running on Allwinner A64 fails to suspend with USB devices
connected as reported by Bhushan Shah <bshah@kde.org>. Reverting
commit 5fbf7a253470 ("usb: musb: fix idling for suspend after
disconnect interrupt") fixes the issue.
Let's add suspend checks also for suspend after disconnect interrupt
quirk handling like we already do elsewhere.
Fixes: 5fbf7a253470 ("usb: musb: fix idling for suspend after disconnect interrupt")

Looks like this fix is still pending, can you guys please apply? This is also
needed on am335x to suspend with devices connected in addition to a64
