Linux kernel 7.4 will enable the Apple Silicon audio driver to use the shared GPIO infrastructure, cleaning up driver interactions and tackling power-management challenges.
Sharing GPIO lines lets multiple kernel components coordinate without conflicts, reducing driver complexity on Apple Silicon devices. The change also addresses the historically difficult power-management integration that has been described as "impossible".

Linux 7.4 introduces use of the shared GPIO infrastructure for the Apple Silicon audio driver.
The shared GPIO model allows multiple drivers or kernel components to safely share the same GPIO lines.
The update also targets the notoriously hard Apple Silicon power-management integration.
