Subject: [PATCH] ARM: dts: stm32: enable USB Host (USBH) EHCI controller on stm32mp157c-ev1
Date: Thu, 17 May 2018 16:36:52 +0200 [thread overview]
Message-ID: <1526567812-6458-1-git-send-email-amelie.delaunay@st.com> (raw)
This patch enables USB Host (USBH) EHCI controller on stm32mp157c-ev1.
As a hub is used between USBH and USB connectors, no need to enable
USBH OHCI controller: all low- and full-speed traffic is managed by the
hub.
