This series brings phy tuning to stm32-usbphyc with a new optional device tree property st,phy-tuning, the elements of which (st,phy-tuning node properties) are also optional. 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.
