sound updates for 4.1-rc1 There have been major modernization with the standard bus: in ALSA sequencer core and HD-audio. Also, HD-audio receives the regmap support replacing the in-house cache register cache code. These changes shouldn't impact the existing behavior, but rather refactoring. In addition, HD-audio got the code split to a core library part and the "legacy" driver parts. This is a preliminary work for adapting the upcoming ASoC HD-audio driver, and the whole transition is still work in progress, likely finished in 4.1. Along with them, there are many updates in ASoC area as usual, too: lots of cleanups, Intel code shuffling, etc. Here are some highlights: ALSA core: - PCM: the audio timestamp / wallclock enhancement - PCM: fixes in DPCM management - Fixes / cleanups of user-space control element management - Sequencer: modernization using the standard bus HD-audio: - Modernization using the standard bus - Regmap support - Use standard runtime PM for codec power saving - Widget-path based power-saving for IDT, VIA and Realtek codecs - Reorganized sysfs entries for each codec object - More Dell headset support ASoC: - Move of jack registration to the card level - Lots of ASoC cleanups, mainly moving things from the CODEC level to the card level - Support for DAPM routes specified by both the machine driver and DT - Continuing improvements to rcar - pcm512x enhacements - Intel platforms updates - rt5670 updates / fixes - New platforms / devices: some non-DSP Qualcomm platforms, Google's Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC Misc: - ice1724: Improved ESI W192M support - emu10k1: Emu 1010 fixes/enhancement
