https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.20 Lots of fixes here, the majority of which are driver specific but there's a couple of core things and one notable driver specific one: - A core fix for a DAPM regression introduced during the component refactoring, we'd lost the code that forced a reevaluation of the DAPM graph after probe (which we suppress during init to save lots of recalcuation) and have now restored it. - A core fix for error handling using the newly added for_each_rtd_codec_dai_rollback() macro. - A fix for the names of widgets in the newly introduced pcm3060 driver, merged as a fix so we don't have a release with legacy names.
2018-11-26ASoC: soc.h: makes snd_soc_of_parse_audio_prefix() inlineKuninori Morimoto
commit 3b7103562c03c ("ASoC: soc-core: add snd_soc_of_parse_node_prefix()") maked snd_soc_of_parse_audio_prefix() as #define. But it'd be better to make this a static inline rather than a #define.

2018-11-23ASoC: soc-core: add snd_soc_of_parse_node_prefix()Kuninori Morimoto
Current ASoC has snd_soc_of_parse_audio_prefix() to get codec_conf settings from DT which is used to avoid DAI naming conflict when CPU/Codec matching. Currently, it is parsing from "top node", but, we want to parse from "each sub node" if sound card had multi cpus/codecs. This patch adds new snd_soc_of_parse_node_prefix() to allow parsing settings from selected node. It is keeping existing snd_soc_of_parse_audio_prefix() by using macro.

2018-11-06ASoC: acpi: define common interface for machine driver configurationPierre-Louis Bossart
The machine drivers may need information provided by the platform driver. Currently the information is passed using pdata specific to each plaform driver. This prevents other drivers, such as SOF, from reusing machine drivers directly. Add a new structure which contains the required fields. This proposal requires a bit more work on the platform side but this generic interface helps reuse code directly.

gcc notices that without either the ac97 bus or the pdata, we never initialize the regmap pointer, which leads to an uninitialized variable access: sound/soc/codecs/wm9712.c: In function 'wm9712_soc_probe': sound/soc/codecs/wm9712.c:666:2: error: 'regmap' may be used uninitialized in this function [-Werror=maybe-uninitialized] Since that configuration is invalid, it's better to return an error here. I tried to avoid adding complexity to the conditions, and turned the #ifdef into a regular if(IS_ENABLED()) check for readability. This in turn requires moving some header file declarations out of an #ifdef. The same code is used in three drivers, all of which I'm changing the same way.

Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which 1) sets bus->chip_init to prevent multiple entrances before device is stopped; 2) enables interrupt. We shouldn't use it for the purpose of resetting device only because 1) when we really want to initialize device, we won't be able to do so; 2) we are ready to handle interrupt yet, and kernel crashes when interrupt comes in.

2018-09-12ASoC: core: add support to card rebindSrinivas Kandagatla
Current behaviour of ASoC core w.r.t to component removal is that it unregisters dependent sound card totally. There is no support to rebind the card if the component comes back. Typical use case is DSP restart or kernel modules itself. With this patch, core now maintains list of cards that are unbind due to any of its depended components are removed and card not unregistered yet. This list is cleared when the card is rebind successfully or when the card is unregistered from machine driver. This list of unbind cards are tried to bind once again after every new component is successfully added, giving a fair chance for card bind to be successful.

In some cases (mainly for x86), we need the DMA coherent buffer with non-cached pages. Although this has been done in each driver side like HD-audio and intel8x0, it can be done cleaner in the core memory allocator. This patch adds the new types, SNDRV_DMA_TYPE_DEV_UC and SNDRV_DMA_TYPE_DEV_UC_SG, for allocating such non-cached buffer pages. On non-x86 architectures, they work as same as the standard SNDRV_DMA_TYPE_DEV and *_SG. One additional change by this move is that we can assure to pass the non-cached pgprot to the vmapped buffer, too. It eventually fixes the case like non-snoop mode without mmap access on HD-audio.

Currently, CODEC to CODEC links don't set this, which causes a NULL pointer dereference: [<4069de54>] (soc_dai_hw_params) from [<40694b68>] (snd_soc_dai_link_event+0x1a0/0x380) Since the ASoC core in general assumes that the substream private_data will be set to a pointer to the snd_soc_pcm_runtime, update the CODEC to CODEC links to respect this.

2018-07-30ALSA: seq: virmidi: Offload the output event processingTakashi Iwai
The virmidi sequencer stuff tries to translate the rawmidi bytes to sequencer events and deliver the packets at trigger callback. The amount of the whole process of these translations and deliveries depends on the incoming rawmidi bytes, and we have no limit for that; this was the cause of a CPU soft lockup that had been reported and fixed recently. Although we've fixed the soft lockup by putting the temporary unlock and cond_resched(), it's rather a quick band aid. In this patch, meanwhile, the event parsing and delivery process is offloaded to a dedicated work, and the trigger callback just kicks it off. It has three merits, at least: - The processing is always done in a sleepable context, which can assure the event delivery with non-atomic flag without hackish is_atomic() usage. - Other relevant codes can be simplified, reducing the lines - It makes me happier Signed-off-by: Takashi Iwai <tiwai@suse.de>
