From mboxrd@z Thu Jan 1 00:00:00 1970 From: mcoquelin.stm32@gmail.com (Maxime Coquelin) Date: Mon, 29 Feb 2016 11:34:39 +0100 Subject: [PATCH] ARM: dts: stm32429i-eval: Add USB HS host mode support Message-ID: <1456742079-8648-1-git-send-email-mcoquelin.stm32@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch adds USB HS support in host mode only. This port supports OTG mode, but the device more is not working properly as of now. Once the device mode fixed, the node will be updated to support OTG.
