Linux Audio Is Being Further Modernized With The 4.1 Kernel

Takashi Iwai sent in his sound driver updates for Linux 4.1, which includes major modernization with the standard bus for ALSA in the sequencer core and HD-audio code.

This sound/audio updates also include the HD-audio code now supporting regmap to replace their in-house register cache code, a split of HD-audio into a core library and "legacy" driver portions, in preparation for the upcoming ASoC HD-audio driver.

The sound update for Linux 4.1 also uses the standard runtime power management code now for codec power savings, improved Dell headset support by HD-audio, Intel platform updates within the ASoC code, support for Google's Storm platform, and various other new codecs are now supported.

More details can be found via the sound pull request.
