Subject[PATCH v3 0/2] Introduce STM32 USB PHY Controller driver
Date
This patchset adds support for STMicroelectronics STM32 USB PHY Controller
(USBPHYC) which is embedded in STM32MP1 SoC.
The STM32 USBPHYC block contains a dual port High Speed UTMI+ PHY and a UTMI
switch that selects either USB OTG controller or USB Host controller for the
second PHY port.

---
Changes in v3:
* Address Kishon comments: move to phy provider + child phy sub-nodes model.
* Remove st,utmi-switch property as the information is now passed through
phy cell for port#2.
* Rework phy init/exit by extracting pll management in dedicated functions.
* Make some clean-up around variable names and defines.

Changes in v2:
* Update diagram to better describe the context.
* Change boolean dt propery st,port2-switch-to-host into u32 st,utmi-switch.
* Silent phy creation failure in case of -EPROBE_DEFER.
