Subject: [PATCH v4 9/9] ARM: dts: stm32: add joystick support on stm32mp157c-ev1
Date: Wed, 27 Feb 2019 10:34:54 +0100 [thread overview]
Message-ID: <1551260094-32570-10-git-send-email-amelie.delaunay@st.com> (raw)
In-Reply-To: <1551260094-32570-1-git-send-email-amelie.delaunay@st.com>
The joystick (B1) on stm32mp157c-ev1 uses gpios on STMFX gpio expander.
These gpios need a pin configuration (push-pull and bias-pull-down),
described under stmfx_pinctrl node.
