Subject: [PATCH 0/6] STM32 USBPHYC PLL management rework

STM32 USBPHYC controls the USB PLL. PLL requires to be powered with 1v1 and 1v8
supplies. To ensure a good behavior of the PLL, during boot, runtime and
suspend/resume sequences, this series reworks its management to fix regulators
issues and improve PLL status reliability.

Amelie Delaunay (6):
  dt-bindings: phy: phy-stm32-usbphyc: move PLL supplies to parent node
  phy: stm32: manage 1v1 and 1v8 supplies at pll activation/deactivation
  phy: stm32: replace regulator_bulk* by multiple regulator_*
  phy: stm32: ensure pll is disabled before phys creation
  phy: stm32: ensure phy are no more active when removing the driver
  phy: stm32: rework PLL Lock detection
