[PATCH] ARM: dts: stm32: add USB Host (USBH) support to stm32mp157c

From: Amelie Delaunay
Date: Tue Apr 24 2018 - 07:25:23 EST


Add support for USBH (USB Host) to STM32MP157C SoC.
USBH is a USB Host controller supporting the standard registers used for
full- and low-speed (OHCI controller) and high-speed (EHCI controller).
