The device has the same behavior as the DualShock 4 in that by default it sends a limited input report (0x1), but after requesting calibration data, it switches to an extended input report (report 49), which adds data for touchpad, motion sensors, battery and more.

There is no appropriate API yet in the Linux kernel to expose these. The controller also provides a classic rumble feature for backwards compatibility. Expose this classic rumble feature using the FF framework.

A dedicated button on the controller handles mute, but software has to configure the device to mute the audio stream. This patch captures the mute button and schedules an output report to mute/unmute the audio stream as well as toggle the mute LED.
