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 v3:
- Add extra PHY_MODEs for updating USB speed instead of adding
new callback.
- Continue to use power_on() for QMP driver as pci-qcom driver
initialization sequence requires pipe_clk to enabled as part
of power_on().
- Fix bug in the usage clk_bulk_ APIs in QMP driver.
- Update handling of fuse values for tune1 parameter in QUSB2
driver for v2 PHY.
- Incorporated other review comments.
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")
