Subject: [PATCH v3 0/3] phy: stm32: add phy tuning support

This series brings phy tuning to stm32-usbphyc with new optional
device tree properties.
A prior patch add resume routine, which is used to restore UTMI
switch and phy tuning configuration, as they can be reset if
deep low power state is achieved.

Amelie Delaunay (3):
  phy: stm32: restore utmi switch on resume
  dt-bindings: phy: phy-stm32-usbphyc: add optional phy tuning
    properties
  phy: stm32: add phy tuning support

---
Changes in v3:
- Use -microamp for current boost
- '|' added after 'description:' on each properties needing this
Changes in v2:
- st,phy-tuning + usb_phy_tuning node removed
- properties are now in phy child nodes
