The HDA links can be switched off when not is use, similarly command DMA can be stopped as well. This calls for a reference counting mechanism on the link by it's users to manage the link power.

2016-04-27ASoC: dmaengine_pcm: Add support for packed transfersMatthias Reichl1-0/+12
dmaengine_pcm currently only supports setups where FIFO reads/writes correspond to exactly one sample, eg 16-bit sample data is transferred via 16-bit FIFO accesses, 32-bit data via 32-bit accesses. This patch adds support for setups with fixed width FIFOs where multiple samples are packed into a larger word. For example setups with a 32-bit wide FIFO register that expect 16-bit sample transfers to be done with the left+right sample data packed into a 32-bit word. Support for packed transfers is controlled via the SND_DMAENGINE_PCM_DAI_FLAG_PACK flag in snd_dmaengine_dai_dma_data.flags If this flag is set dmaengine_pcm doesn't put any restriction on the supported formats and sets the DMA transfer width to undefined. This means control over the constraints is now transferred to the DAI driver and it's responsible to provide proper configuration and check for possible corner cases that aren't handled by the ALSA core.

2016-04-26ALSA: hda - Update BCLK also at hotplug for i915 HSW/BDWTakashi Iwai1-3/+2
The recent bug report suggests that BCLK setup for i915 HSW/BDW needs to be updated at each HDMI hotplug, not only at initialization and resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at ELD notification, too. Otherwise the HDMI audio may be out of sync and played in a wrong pitch. However, the HDA codec driver has no access to the controller registers, and currently the code managing these registers is in hda_intel.c, i.e. local to the controller driver. For allowing the explicit BCLK update from the codec driver, as in this patch, the former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA controller driver and intel_pin_eld_notify() in HDMI codec driver. Along with this change, snd_hdac_get_display_clk() gets dropped as it's no longer used.

2016-04-21ALSA: hda - Fix possible race on regmap bypass flipTakashi Iwai1-0/+2
HD-audio driver uses regmap cache bypass feature for reading a raw value without the cache. But this is racy since both the cached and the uncached reads may occur concurrently. The former is done via the normal control API access while the latter comes from the proc file read. Even though the regmap itself has the protection against the concurrent accesses, the flag set/reset is done without the protection, so it may lead to inconsistent state of bypass flag that doesn't match with the current read and occasionally result in a kernel WARNING like: WARNING: CPU: 3 PID: 2731 at drivers/base/regmap/regcache.c:499 regcache_cache_only+0x78/0x93 One way to work around such a problem is to wrap with a mutex. But in this case, the solution is simpler: for the uncached read, we just skip the regmap and directly calls its accessor. The verb execution there is protected by itself, so basically it's safe to call individually. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=116171 Signed-off-by: Takashi Iwai <tiwai@suse.de>

The hdmi-codec is a platform device driver to be registered from drivers of external HDMI encoders with I2S and/or spdif interface. The driver in turn registers an ASoC codec for the HDMI encoder's audio functionality. The structures and definitions in the API header are mostly redundant copies of similar structures in ASoC headers. This is on purpose to avoid direct dependencies to ASoC structures in video side driver.

2016-04-04ALSA: hda - Update chmap tlv to report sink's capabilitySubhransu S. Prusty1-0/+2
The existing TLV callback implementation copies all of the cea_channel_speaker_allocation map table to the TLV container irrespective of what is reported by sink. This is of little use to the userspace application. With this patch, it parses the spk_alloc block as queried from the ELD, and copies only the corresponding mapping channel allocation entries from the cea channel speaker allocation table. Thus the user can parse the TLV container to identify sink's capability and set the channel map accordingly. It shouldn't impact the behavior in AMD chipset, as this makes use of already parsed spk alloc block to calculate the channel map. Signed-off-by: Subhransu S.

2016-03-28ALSA: hda - Add the pin / port mapping on Intel ILK and VLVTakashi Iwai1-5/+5
Intel IronLake and ValleyView platforms have different HDMI widget pin and digital port mapping from other newer ones. The recent ones (HSW+) have NID 0x05 to 0x07 for port B to port D, while these chips have NID 0x04 to 0x06. For adapting this mapping, pass the codec object instead of the bus object to snd_hdac_sync_audio_rate() and snd_hdac_acomp_get_eld() so that they can check the codec ID and calculate the mapping properly. The changes in the HDMI codec driver side will follow in the later patch. Signed-off-by: Takashi Iwai <tiwai@suse.de>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.6 The main thing in terms of the core this time around has been some additional framework work for dynamic topologies (though we *still* don't appear to have a stable ABI for the topology code, it's probably worth considering if this will ever happen...). Otherwise the work has almost all been in the drivers: - HDMI support for Sky Lake, along with other fixes and enhancements for the Intel drivers. - Lots of improvements to the Renesas drivers. - Capture support for Qualcomm drivers. - Support for TI DaVinci DRA7xxx devices. - New machine drivers for Freescale systems with Cirrus CODECs, Mediatek systems with RT5650 CODECs. - New CPU drivers for Allwinner S/PDIF controllers - New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.

2016-03-08ALSA: hda - Fix unexpected resume through regmap code pathTakashi Iwai1-0/+2
HD-audio driver has a mechanism to trigger the runtime resume automatically at accessing the verbs. This auto-resume, however, causes the mutex deadlock when invoked from the regmap handler since the regmap keeps the mutex while auto-resuming. For avoiding that, there is some tricky check in the HDA regmap handler to return -EAGAIN error to back-off when the codec is powered down. Then the caller of regmap r/w will retry after properly turning on the codec power. This works in most cases, but there seems a slight race between the codec power check and the actual on-demand auto-resume trigger. This resulted in the lockdep splat, eventually leading to a real deadlock. This patch tries to address the race window by getting the runtime PM refcount at the check time using pm_runtime_get_if_in_use(). With this call, we can keep the power on only when the codec has been already turned on, and back off if not. For keeping the code consistency, the code touching the runtime PM is stored in hdac_device.c although it's used only locally in hdac_regmap.c.

2016-02-26ALSA: hda - Loop interrupt handling until really clearedTakashi Iwai1-1/+1
Currently the interrupt handler of HD-audio driver assumes that no irq update is needed while processing the irq. But in reality, it has been confirmed that the HW irq is issued even during the irq handling. Since we clear the irq status at the beginning, process the interrupt, then exits from the handler, the lately issued interrupt is left untouched without being properly processed. This patch changes the interrupt handler code to loop over the check-and-process. The handler tries repeatedly as long as the IRQ status are turned on, and either stream or CORB/RIRB is handled. For checking the stream handling, snd_hdac_bus_handle_stream_irq() returns a value indicating the stream indices bits. Other than that, the change is only in the irq handler itself.

2016-02-23ALSA: jack: Allow building the jack layer without input deviceTakashi Iwai1-9/+14
Since the recent integration of kctl jack and input jack layers, we can basically build the jack layer even without input devices. That is, the jack layer itself can be built with conditional to enable the input device support or not, while the users may enable always CONFIG_SND_JACK unconditionally. For achieving it, this patch changes the following: - A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate whether the jack layer supports the input device, - A few items in snd_jack struct and relevant codes are conditionally built upon CONFIG_SND_JACK_INPUT_DEV, - The users of CONFIG_SND_JACK drop the messy dependency on CONFIG_INPUT. This change also automagically fixes a potential bug in HD-audio driver Arnd reported, where the NULL or uninitialized jack instance is dereferenced.

Similarly in the latter case, it calls snd_rawmidi_transmit_peek() and snd_rawmidi_tranmit_ack() separately without protection, so they are racy as well. The patch tries to address these issues by the following ways: - Introduce the unlocked versions of snd_rawmidi_transmit_peek() and snd_rawmidi_transmit_ack() to be called inside the explicit lock. - Rewrite snd_rawmidi_transmit() to be race-free (the former case). - Make the split calls (the latter case) protected in the rawmidi spin lock.

We really need to get to the point where that can be done. - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come. - New drivers for a number of Imagination Technologies IPs. - Lots of new features and cleanups for the Renesas drivers. - ANC support for WM5110. - New driver for Atmel class D speaker drivers. - New drivers for Cirrus CS47L24 and WM1831. - New driver for Dialog DA7128. - New drivers for Realtek RT5659 and RT56156. - New driver for Rockchip RK3036. - New driver for TI PC3168A # gpg: Signature made Wed 23 Dec 2015 00:42:40 GMT using RSA key ID 5D5487D0 # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>" # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 3F25 68AA C269 98F9 E813 A1C5 C3F4 36CA 30F5 D8EB # Subkey fingerprint: ADE6 68AA 6757 18B5 9FE2 9FEA 24D6 8B72 5D54 87D0

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin1-2/+6
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.

2016-01-10ASoC: dwc: add quirk to override COMP_PARAM_1 registerMaruthi Srinivas Bayyavarapu1-0/+1
DWC for capture in ACP 2.x IP reports playback and capture capabilities though it supports only capture. Added a quirk to override default value to represent capture capability only.

2016-01-10ASoC: Support registering a DAI dynamicallyMengdong Lin2-0/+4
Define API snd_soc_register_dai() to add a DAI dynamically and create the DAI widgets. Topology can use this API to register DAIs when probing a component with topology info. These DAIs's playback & capture widgets will be freed when the sound card is unregistered and the DAIs will be freed when cleaning up the component. And a dobj is embedded into the struct snd_soc_dai_driver. Topology can use the dobj to find the DAI drivers created by it and free them when the topology component is removed.
