+title: Analog Devices ADG1712 quad SPST switch GPIO controller

+description: |
+  Bindings for Analog Devices ADG1712 quad single-pole, single-throw (SPST)
+  switch controlled by GPIOs. The device features four independent switches,
+  each controlled by a dedicated GPIO input pin.
+
+  Each GPIO line exposed by this controller corresponds to one of the four
+  switches (SW1-SW4) on the ADG1712. Setting a GPIO line high enables the
+  corresponding switch, while setting it low disables the switch.
+
