This series introduces support for the Azoteq IQS7210A, IQS7211A and
IQS7211E trackpad/touchscreen controllers. Optimized for wearable
applications, these devices track up to two contacts and are capable
of reporting an array of gestures.

The IQS7210A includes an additional channel to support an inductive
or capacitive button, while the IQS7211E adds an advanced assortment
of gestures. All three devices are demonstrated in [1].

These devices can be configured during production using OTP memory,
or over I2C using the device tree. For the latter case, the binding
covers all major parameters called out by the vendor in [2].
