In ASoC side, there is one fix in the common code, but it's just trivial additions of static inline functions for CONFIG_PM=n. The rest are various device-specific small fixes.

Merge tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "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

ASoC: rsnd: 1st DMAC dma-names cares subnode
Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver.
dma-names on DT was implemented as no difference between 1st / 2nd DMAC's, since rsnd had assumed that both DMACs are implemented as DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented as non DMAEngine, and it doesn't need dma-names anymore. So, this dma-names rule is no longer needed.
And additionally, dma-names was assumed that it has all (= SSI/SSIU/SRC/DVC) nodes under sound node.
In upstream code, no SoC/platform is supporting DMA for rsnd driver yet. This means there is no compatible issue if this patch changes dma-names's rule of DT.
This patch assumes dma-names for 1st DMAC are tx/rx base, and listed in each SSI/SRC/DVC subnode ex) rcar_sound,dvc { dvc0: dvc@0 { dmas = <&audma0 0xbc>; dma-names = "tx"; }; ...
rcar_sound,src { src0: src@0 { ... dmas = <&audma0 0x85>, <&audma1 0x9a>; dma-names = "rx", "tx"; }; ...

ASoC: rsnd: add dma.c for Audio DMAC / Audio DMAC peri peri
Renesas sound driver had been assumed that Audio DMAC / Audio DMAC peri peri are implemented by DMAEngine. But, result of DMA ML discussion, it was concluded that it is not a general purpose DMAC. And it should be moved from current DMAEngine to rsnd driver. So, Audio DMAC peri peri become non DMAEngine.
OTOH, ALSA SoC has soc-generic-dmaengine-pcm implementation. but it seems difficult to use this generic implementation on rsnd driver at this point, since it needs to fallback to PIO mode if DMA can't use. and additionally it needs 2 DMAC (= Audio DMAC / Audio DMAC peri peri). These are not "generic" feature.
Of course I will try to use this generic dmaengine in the future somehow, but just use current style at this point until it can formally use 2 DMACs. This patch adds new dma.c and moves current dma code to dma.c from core.c.
