Subject: [PATCH 5.4 018/153] ARM: dts: at91: sam9g20ek: enable udc vbus gpio pinctrl
Date: Mon, 5 Dec 2022 20:09:02 +0100 [thread overview]
Message-ID: <20221205190809.270570473@linuxfoundation.org> (raw)
In-Reply-To: <20221205190808.733996403@linuxfoundation.org>
From: Michael Grzeschik <m.grzeschik@pengutronix.de>
[ Upstream commit 40a2226e8bfacb79dd154dea68febeead9d847e9 ]
We set the PIOC to GPIO mode. This way the pin becomes an
input signal will be usable by the controller. Without
this change the udc on the 9g20ek does not work.
