Subject: [PATCH v3 09/16] usb: phy: tegra: Assert reset on ULPI close instead of deasserting it
Date: Sat, 28 Dec 2019 23:33:51 +0300	[thread overview]
Message-ID: <20191228203358.23490-10-digetx@gmail.com> (raw)
In-Reply-To: <20191228203358.23490-1-digetx@gmail.com>

Apparently ULPI was meant to be put into reset on PHY's shutdown (which is
active-low state of the GPIO), but there is a typo in the code.
