Subject: [PATCH 0/2] gpio: Add support for ADG1712 quad SPST switch

This patch series adds support for the Analog Devices ADG1712 quad
single-pole/single-throw (SPST) switch GPIO driver.

The ADG1712 contains four independent SPST switches and operates with a
low-voltage single supply range from +1.08V to +5.5V or a low-voltage
dual supply range from ±1.08V to ±2.75V. Each switch is controlled by
a dedicated GPIO input pin.

The driver provides a GPIO controller interface where each GPIO line
controls one of the four independent analog switches on the ADG1712.
This allows software to dynamically control signal routing through
the analog switches.

Patch 1 adds the device tree bindings documentation.
Patch 2 adds the GPIO driver implementation.
