Some Samsung devices that use the midas_wm1811 driver use a GPIO-based method for detecting whether the headset jack is plugged in, as well as detecting which headset buttons are pressed. There are two GPIOs: a "headset detect" GPIO responsible for detecting jack insertion, and a "headset key" GPIO which triggers when a button on the headset is pressed. The plug type and the button pressed are determined based on information from an ADC channel. The headset mic is enabled by a headset mic bias regulator. Add support for the GPIO-based headset jack detection mechanism, and make it configurable from the device tree. This implementation borrows somewhat from the aries_wm8994.c driver, though there are a few changes to make the code cleaner, and to add support for DT-based configuration. Notably, a dependency on IIO is introduced, to accommodate the ADC reading requirement.
