Subject: [PATCH 5/6] phy: rockchip-inno-usb2: Handle bvalid falling
Date: Wed, 13 Apr 2022 22:22:56 -0500 [thread overview]
Message-ID: <20220414032258.40984-6-samuel@sholland.org> (raw)
In-Reply-To: <20220414032258.40984-1-samuel@sholland.org>
Some SoCs have a bvalid falling interrupt, in addition to bvalid rising.
This interrupt can detect OTG cable plugout immediately, so it can avoid
the delay until the next scheduled work.
