Subject: [PATCH v3 3/4] usb: dwc2: fix unbalanced phy control
Date: Mon, 21 Sep 2015 12:16:11 +0200	[thread overview]
Message-ID: <1442830572-6765-4-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1442830572-6765-1-git-send-email-m.szyprowski@samsung.com>

Even when DWC2 is in (internal) suspended state, it should disable PHY
in suspend and then enable it in resume. This patch fixes unbalanced PHY
control sequence.
