This capacitance to digital converter (CDC) driver is compliant with the IIO ABI. Note, not all features supported (e.g. window event modes) but the driver should be in a useful functional state. The cleanup was done against QEMU emulation of the device rather than actual hardware. Whilst this was a bit of an experiment, it made it easy to confirm that the driver remained in a consistent working state through the various refactors. If it worked in the first place, it should still be working after this cleanup. Given some IIO drivers require expensive hardware setups, (not particularly true with this one) the use of QEMU may provide a viable way forward for providing testing during code changes where previously we'd had to rely on sharp eyes and crossed fingers. Note, no explicit MAINTAINERS entry as it will be covered by the generic catch-alls for ADI and IIO drivers which are sufficient.
