2016-11-03ASoC: Intel: Skylake: Add support for specifying D0i3 configurationVinod Koul
Not all use cases can support Doi3. Only certain use cases like hot word detection, deep buffering can support D0i3 based on resource requirement. So, pass the D0i3 capability for the FE/BE copier using topology. This will be used to take a decision for D0i3 mode entry/exit.

2016-11-03ASoC: Intel: Skylake: Add support for LPModeVinod Koul
For D0i3, we need to tell DSP to run the pipelines in LP mode. This information is kept in topology and passed to driver as an attribute for pipe. So add a new tuple for lpmode and program the pipe based on value set.

2016-11-03ASoC: Intel: Skylake: Add D0iX callbacksJayachandran B

2016-11-03ASoC: Intel: Skylake: Add support for programming D0i3CPardha Saradhi K
To set the controller in D0i3 mode, the driver needs to set D0i3C register after DSP is quiesced.

2016-11-03ASoC: Intel: Skylake: Add D0iX IPCsPardha Saradhi K
The audio DSP supports intermediate power states between D0 and D3 states. These states are D0i0 and D0i3 states. Collectively we refer these two states as D0iX states. To set or wake up from these states, driver also needs to send an IPC "Set D0iX IPC" before doing anything else. Add support for this new IPC messages.

2016-11-03ASoC: Intel: Add sst_ipc_tx_message_nopmVinod Koul
If the DSP is in low power mode, it needs to be woken up by a "wake" IPC to set it into the D0 state before we can send any other IPC command. The call flow is that the driver calls sst_ipc_tx_message_wait() to send any IPC and this call checks if the device is in low power mode and in that case we need to send the wake IPC. So add a new IPC nopm variant which can be called from driver and doesn't check for power state (as we already know that) and avoids circular dependency of again checking power state.

2016-11-03ASoC: topology: ABI - Add flags and private data to PCMMengdong Lin
This is the remaining update to PCM ABI object of version 5. The flags will be applied to FE (Front End) links and can also be used by physical links. The private data is reserved for future extension, so offset update will add the private data size. Now user space is using ABI v4, and the previous patch "ASoC: topology: make PCM backward compatible from ABI v4" can assure the backward compatibility.

User space may not always set a valid FE DAI driver's name, FE DAI link's name, stream name or cpu DAI name. In such cases, there are all ZERO in these name string buffers of a topology PCM object.

2016-11-03ASoC: topology: Make PCM backward compatible from ABI v4Mengdong Lin
This patch adds support for old version 4 of PCMs (FE DAI & DAI links). Topology ABI v5 added new fields to stream caps and thus changed PCMs. Since user space may still uses v4, kernel will check the ABI version by comparing the object size. If user space uses v4 of PCMs, kernel will create the latest version of PCMs from the old version, and use the new version internally to create FE DAI & DAI links. Because these new created PCM elements will be freed later, kernel need duplicate the name strings of DAI driver and DAI links when creating them.

2016-11-02ASoC: dapm: Implement stereo mixer control supportChen-Yu Tsai
While DAPM is mono or single channel, its controls can be shared between widgets, such as sharing one stereo mixer control between the left and right channel widgets. An example such as the following routes [Line In Left]----------<Line In Playback Switch>-------[Left Mixer] ^ ^ ^ | ^ (inputs) (paths) <shared stereo mixer control> (outputs) v v | v v [Line In Right]---------<Line In Playback Switch>-------[Right Mixer] where we have separate widgets and paths for the left and right channels from "Line In" to "Mixer", but a shared stereo mixer control for the 2 paths. This patch introduces support for such shared mixer controls, allowing more than 1 path to be attached to a single stereo control, and being able to control left/right channels independently.

2016-11-02ASoC: dapm: Support second register for DAPM control updatesChen-Yu Tsai

For codecs that use custom events which call into DAPM to do updates, also clear struct snd_soc_dapm_update before using it, so the second set of fields remains clean.

This patch fixes lpass-platform driver which was broken in v4.9-rc1. lpass_pcm_data data structure holds information specific to stream. Holding a single private pointer to it in global lpass_data will not work, because it would be overwritten by for each pcm instance. This code was breaking playback when we have both playback and capture pcm streams, as playback settings are over written by capture settings. Fix this by moving channel allocation logic out of pcm_new to pcm_open so that we can store the stream specific information in private_data of snd_pcm_runtime.

2016-10-28ASoC: samsung: get access to DMA engine early to defer probe properlyMarek Szyprowski
ASoC Samsung sub-drivers tried to get access to their DMA engine controllers as a last step in driver probe. If a DMA engine was not available yet, samsung_asoc_dma_platform_register() function ended in -EPROBE_DEFER, but the driver already registered its component to ASoC core. This patch moves samsung_asoc_dma_platform_register() call before registering any components, to the common place, where driver was gathering all needed resources. In case of Samsung Exynos i2s driver the issue was even worse. The driver managed already to register its secondary DAI platform device before even getting the DMA engine access. That together with -EPROBE_DEFER error code from samsung_i2s_probe() immediately triggered another round of deferred probe retry and in turn endless loop of driver probing.
