Subject: [PATCH v1 0/6] phy: qualcomm: Add suspend/resume support for USB PHYs
Date: Fri, 21 Jul 2017 16:31:55 +0530	[thread overview]
Message-ID: <1500634921-25914-1-git-send-email-mgautam@codeaurora.org> (raw)

These patches add support for runtime PM in Qualcomm QUSB2 and
QMP USB PHY drivers.
It also requires notifying usb3 PHY of USB mode (device/host)
so that driver can decide whther to power down PHY or not. This
can later be extended to add support in PHY drivers to enable
wakeup events detection on dp/dm or SS lines (for LFPS or
rx-terminations) only for bus suspend case.

Also addresses a requirement where USB PHYs must be powered
before initialization.
