pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver
This patch adds pinctrl/GPIO driver for STMicroelectronics Multi-Function eXpander (STMFX) GPIO expander. STMFX is an I2C slave controller, offering up to 24 GPIOs. The driver relies on generic pin config interface to configure the GPIOs. Signed-off-by: Amelie Delaunay <amelie.delaunay@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
