From mboxrd@z Thu Jan 1 00:00:00 1970 From: k@japko.eu (Krzysztof Adamski) Date: Tue, 5 Dec 2017 23:03:58 +0100 Subject: [PATCH v2] ARM: dts: sun8i: h3: enable USB OTG for NanoPi Neo board In-Reply-To: <20171205090706.et5a7dizkhn6auje@flea.lan> References: <20171205090706.et5a7dizkhn6auje@flea.lan> Message-ID: <20171205220358.GA28161@t440.localdomain> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Similarly to Orange Pi Zero, NanoPi Neo board has an USB OTG port with an ID pin but with unpowered VBUS. This patch enables this port in forced peripheral mode. ohci/ehci nodes are still enabled since the host mode may work if external power source is used. In that case, the mode can be switched for example via sysfs. The same strategy is used for Orange Pi Zero board DTS.
