gpiolib: make legacy interfaces optional

2025-07-24T14:24:49+00:00

The traditional interfaces are only used on a small number of ancient boards. Make these optional now so they can be disabled by default.

gpio: Add new gpio-macsmc driver for Apple Macs

2025-07-24T08:47:33+00:00

This driver implements the GPIO service on top of the SMC framework on Apple Mac machines. In particular, these are the GPIOs present in the PMU IC which are used to control power to certain on-board devices. Although the underlying hardware supports various pin config settings (input/output, open drain, etc.), this driver does not implement that functionality and leaves it up to the firmware to configure things properly. We also don't yet support interrupts/events. This is sufficient for device power control, which is the only thing we need to support at this point. More features will be implemented when needed. To our knowledge, only Apple Silicon Macs implement this SMC feature.

gpio: introduce utilities for synchronous fake device creation

2025-02-24T13:57:39+00:00

Both gpio-sim and gpio-virtuser share a mechanism to instantiate a platform device, wait for probe completion, and retrieve the probe success or error status synchronously. With gpio-aggregator planned to adopt this approach for its configfs interface, it's time to factor out the common code. Add dev-sync-probe.[ch] to house helper functions used by all such implementations. No functional change.
