2016-11-30ASoC: nau8825: lock longer to avoid playback pop upon resumeJohn Hsu1-6/+6
There is an issue about pop noise in NAU88L25 as follows. Issue 54078: Chell_headphone pop back from S3 (1)Play directly to hw, bypassing CRAS: sox -b 16 -n -t alsa hw:0,0 synth sine 200 sine 200 (2)Close lid or powerd_dbus_suspend, then press a key to resume. (3)no audio after resume (4)Audio will be back after close then reopen the pcm device. After verification, we find one defect is that semaphone lock is not long enough and expired. In this situation, the playback comes back early but pauses a while to wait for the crosstalk detection done. But the detection spends too much time and lock time is up. Therefore, the playback and jack detection sequence interfere to each other. That breaks sequence and makes noise. The driver extends the lock time for the issue.

The usage pattern of kthread worker in Intel SST drivers can be replaced gracefully with the normal workqueue, which is more light- weight and easier to manage in general. Let's do it. While in the replacement, move the schedule_work() call inside the spinlock for excluding the race, too.

2016-11-30ASoC: arizona: Use component pin control functionsRichard Fitzgerald6-9/+18
We need to modify the state of some of our own pins and are currently not taking account that the pin name may have a name_prefix applied to it. Replace the snd_soc_dapm_x_pin functions with the equivalent snd_soc_component_x_pin functions so that any name_prefix will be handled automatically.

2016-11-30ASoC: core: Add component pin control functionsRichard Fitzgerald1-0/+199
It's often the case that a codec driver will need to control its own pins. However, if a name_prefix has been applied to this codec it must be included in the name passed to any of the snd_soc_dapm_x_pin() functions. The behaviour of the existing pin control functions is reasonable, since you may want to search for a fully-specified name within the scope of an entire card. This means that we can't apply the prefix in these functions because it will break card-scope searches. Constructing a prefixed string "manually" in codec drivers leads to a lot of repetition of the same code. To make this tidier in codec drivers this patch adds a new set of equivalent functions that take a struct snd_soc_component instead of a dapm context and automatically add the component's name_prefix to the given name. This makes it a simple change in codec drivers to be prefix-safe. The new functions are not quite trivial enough to be inlines and the compiler won't be able to compile-away any part of them. Although it looks somewhat inefficient to have to allocate a temporary buffer and combine strings, the current design of the widget list doesn't lend itself to a more optimized implementation - it's a single list of all widgets on a card and is searched linearly for a matching string. As pin state changes are generally low-frequency events it's unlikely to be a significant issue - at least not enough to rewrite the widget list handling just for this.

2016-11-28dbri: Fix compiler warningTushar Dave1-10/+16
dbri uses 'u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit DMA and therefore dma_addr_t became of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. sound/sparc/dbri.c: In function ‘snd_dbri_create’: sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’ For the record, dbri(sbus) driver never executes on sun4v. Therefore even though 64bit DMA is enabled on SPARC, dbri continues to use legacy iommu that guarantees DMA address is always in 32bit range. This patch resolves above compiler warning.

Current Renesas Sound driver requests DMA channel when .probe timing, and release it when .remove timing. And use DMA on .start/.stop But, Audio DMAC power ON was handled when request timing (= .probe), and power OFF was when release timing (= .remove). This means Audio DMAC power is always ON during driver was enabled. The best choice to solve this issue is that DMAEngine side handle this. But current DMAEngine API design can't solve atmic/non-atmic context issue for power ON/OFF. So next better choice is sound driver request/release DMA channel each time.

2016-11-22ASoC: wm_adsp: Firmware controls should be added as codec controlsRichard Fitzgerald2-5/+5
We were adding firmware controls as card controls (using snd_soc_add_codec_controls). The DSP is part of a specific codec so we should be adding them as codec controls. Adding as codec controls also means that if the codec has a name_prefix it will be added to the control name, which won't happen when adding as a card control. As that was the only use of the card pointer in struct wm_adsp it can be removed. For ADSP2 codecs a wm_adsp2_codec_probe() was added since the original control handling was written, and that's the logical place to store a pointer to the codec rather than delaying it until the codec is powered-up. For ADSP1 we don't use a codec_probe() stage so the codec pointer initialization replaces the original card pointer initialization in wm_adsp1_event().

It's the code trying to clear drvdata of the assigned usb_device where the usb_device itself was already released in usb_release_dev() after the disconnect callback. This patch fixes it by checking whether the code path is via the disconnect callback, i.e. chip->shutdown flag is set. Fixes: 79289e24194a ('ALSA: usb-audio: Refer to chip->usb_id for quirks...')

2016-11-14ASoC: lpass-platform: fix uninitialized variableLinus Torvalds1-0/+1
In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data usage") the stream specific information initialization was broken, with the dma channel information not being initialized if there was no alloc_dma_channel() helper function. Before that, the DMA channel number was implicitly initialized to zero because the backing store was allocated with devm_kzalloc(). When the init code was rewritten, that implicit initialization was lost, and gcc rightfully complains about an uninitialized variable being used.
