891a96f65a phy: qcom-qusb2: Add support for runtime PM 
Disable clocks and enable DP/DM wakeup interrupts when
suspending PHY.
Core driver should notify speed to PHY driver to enable
appropriate DP/DM wakeup interrupts polarity in suspend state.

4a705d9b3e phy: qcom-qusb2: Add support for QUSB2 V2 version 
Use register layout to add additional registers present
on QUSB2 PHY V2 version for PHY initialization.
Other than new registers on V2, following two register's
offset and bit definitions are different: POWERDOWN control
and PLL_STATUS.

c71dabf27c phy: qcom-qusb2: Add support for different register layouts 
New version of QUSB2 PHY has some registers offset changed.
Add support to have register layout for a target and update
the same in phy_configuration.

937e17f36a phy: qcom-qusb2: Power-on PHY before initialization 
PHY must be powered on before turning ON clocks and
attempting to initialize it. Driver is exposing
separate init and power_on routines for this.
Apparently USB dwc3 core driver performs power-on
after init. Also, poweron and init for QUSB2 PHY
need to be executed together always, hence remove
poweron callback from phy_ops and explicitly perform
this from init, similar changes needed for poweroff.

0b56e9a7e8 phy: Group vendor specific phy drivers 
Adding vendor specific directories in phy to group
phy drivers under their respective vendor umbrella.

Also updated the MAINTAINERS file to reflect the correct
directory structure for phy drivers.
