Subject: [PATCH 5/5] ARM: dts: stm32: add joystick support on stm32746g-eval
Date: Wed, 11 Apr 2018 11:47:05 +0200 [thread overview]
Message-ID: <1523440025-18077-6-git-send-email-amelie.delaunay@st.com> (raw)
In-Reply-To: <1523440025-18077-1-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 stmfxpinctrl node.
