[PATCH v2 0/4] Add STM32 USBPHYC to stm32mp157c

[Amelie Delaunay]

This series adds support for STM32 USB PHY Controller (USBPHYC) to
stm32mp157c SoC and enables it on stm32mp157c-ev1 board.

---
Changes in v2:
* Add reset dt-bindings include
* Add fixed regulators
* Enable CONFIG_PHY_STM32_USBPHYC in multi_v7_defconfig

[PATCH v2 2/4] ARM: dts: stm32: add supplies to usbphyc ports on stm32mp157c-ed1

[Amelie Delaunay]

USBPHYC ports require 3 supplies: 3v3, 1v1 and 1v8.
This patch adds the corresponding properties to usbphyc ports on
stm32mp157c-ed1 board.
