[PATCH v3 00/18] HID: steelseries: Add support for Arctis headset lineup

[Sriman Achanta]

This patch series adds comprehensive support for the SteelSeries Arctis
wireless gaming headset lineup to the hid-steelseries driver.

The current driver provides only basic battery monitoring for Arctis 1
and Arctis 9. This series extends support to 25+ Arctis models with
full feature control including sidetone, auto-sleep, microphone
controls, volume limiting, and Bluetooth settings.

The driver restructure uses a capability-based device info system to
cleanly handle the varying feature sets across different Arctis
generations while maintaining support for the legacy SRW-S1 racing
wheel.

The driver also sets up future support for async device control which
is currently implemented for the Arctis Nova 7 Gen 2 and Post-January update
Gen 1 devices as implemented.

Tested on Arctis Nova 7 (0x2202) and Arctis Nova 7 (0x22a1). All other
implementation details are based on the reverse engineering done in the
HeadsetControl library (902e9bc).

Changes since v2:
* Expose audio related controls via ALSA mixers
* Implement async inputs from supported devices with known protocols
* Overall code cleanup and improvements to initalization logic
* Fixed several logical and protocol issues for Arctis 7 and 9
