Subject: [PATCH v4 6/9] ARM: dts: stm32: add joystick support on stm32746g-eval
Date: Wed, 27 Feb 2019 10:34:51 +0100	[thread overview]
Message-ID: <1551260094-32570-7-git-send-email-amelie.delaunay@st.com> (raw)
In-Reply-To: <1551260094-32570-1-git-send-email-amelie.delaunay@st.com>

The joystick (B3) on stm32746g-eval uses gpios on STMFX gpio expander.
These gpios need a pin configuration (push-pull and bias-pull-up),
described under stmfx_pinctrl node.
