[PATCH v3 00/16] Support for Qualcomm QUSBv2 and QMPv3 USB PHYs

[Manu Gautam <mgautam@codeaurora.org>]

QUSB-v2 and QMP-v3 USB PHYs are present on Qualcomm's 14nm
and 10nm SOCs.
This patch series adds support for runtime PM for these
USB PHYs and adds fixes in drivers to follow PHY reset and
initialization sequence as per hardware programming manual.

Changes since v2:
- Drop sw-vbus override related patches as dwc3 glue driver to
  take care of same.
- Don't read current linestate but rather rely on current speed
  which will be notified by core driver. This is required to
  have correct polarity of wakeup events detection in PHY.

Changes since v1:
- Incorporated review comments.
- Fixes to align with hardware programming manual.
- Added support for QUSBv2 and QMPv3 PHYs.
- Enable DP/DM asynchronous interrupts from QUSB2 USB2 PHY
  for remote-wakeup.
- Enable LFPS and RX-TERM detection for attach and detach
  events from QMP USB3 PHY for remotewakeup.
- Update sw-vbus override in PHY wrapper for device mode.
- Dropped one dwc3 patch from this series which I will submit
  with other dwc3 patches. ("usb: dwc3: core: Notify USB3 PHY as
  well for DRD modes")
