Subject: [PATCH v3 6/9] usb: chipidea: tegra: Support runtime PM
Date: Fri, 18 Dec 2020 15:02:43 +0300	[thread overview]
Message-ID: <20201218120246.7759-7-digetx@gmail.com> (raw)
In-Reply-To: <20201218120246.7759-1-digetx@gmail.com>

Tegra PHY driver now supports waking up controller from a low power mode.
Enable runtime PM in order to put controller into the LPM during idle.
