https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.19 This is the usual set of small fixes scatterd around various drivers, plus one fix for DAPM and a UAPI build fix. There's not a huge amount that stands out here relative to anything else.
2018-09-12sound: don't call skl_init_chip() to reset intel skl socYu Zhao1-0/+1
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. Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset device properly.

2018-08-15ASoC: dapm: Fix NULL pointer deference on CODEC to CODEC DAIsCharles Keepax1-0/+1
Commit a655de808cbde ("ASoC: core: Allow topology to override machine driver FE DAI link config.") caused soc_dai_hw_params to be come dependent on the substream private_data being set with a pointer to the snd_soc_pcm_runtime. 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.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.19 A fairly big update, including quite a bit of core activity this time around (which is good to see) along with a fairly large set of new drivers. - A new snd_pcm_stop_xrun() helper which is now used in several drivers. - Support for providing name prefixes to generic component nodes. - Quite a few fixes for DPCM as it gains a bit wider use and more robust testing. - Generalization of the DIO2125 support to a simple amplifier driver. - Accessory detection support for the audio graph card. - DT support for PXA AC'97 devices. - Quirks for a number of new x86 systems. - Support for AM Logic Meson, Everest ES7154, Intel systems with RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707.
2018-08-02ASoC: core: remove support for card rebind using component frameworkSrinivas Kandagatla1-7/+0
DRM based audio components get registered inside the component framework bind callback. However component framework has a big mutex lock taken for every call to component_add, component_del and bind, unbind callbacks. This can lead to deadlock situation if we are trying to add new/remove component within a bind/unbind callbacks. Which is what was happening with bcm2837 rpi 3. Revert this change till we sort out the mutex issue.

2018-08-01ALSA: seq: Minor cleanup of MIDI event parser helpersTakashi Iwai1-4/+2
snd_midi_event_encode_byte() can never fail, and it can return rather true/false. Change the return type to bool, adjust the argument to receive a MIDI byte as unsigned char, and adjust the comment accordingly. This allows callers to drop error checks, which simplifies the code. Meanwhile, snd_midi_event_encode() helper is used only in seq_midi.c, and it can be better folded into it. This will reduce the total amount of lines in the end.

2018-07-30ALSA: seq: virmidi: Offload the output event processingTakashi Iwai1-0/+1
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>

Actually almost all of them are about setting the format, so it's far better to provide a common helper snd_mask_set_format() to pass SNDRV_PCM_FORMAT_* directly without the cast.

2018-07-17ALSA: hda: Make audio component support more genericTakashi Iwai2-36/+64
This is the final step for more generic support of DRM audio component. The generic audio component code is now moved to its own file, and the symbols are renamed from snd_hac_i915_* to snd_hdac_acomp_*, respectively. The generic code is enabled via the new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is kept as the super-class. Along with the split, three new callbacks are added to audio_ops: pin2port is for providing the conversion between the pin number and the widget id, and master_bind/master_unbin are called at binding / unbinding the master component, respectively. All these are optional, but used in i915 implementation and also other later implementations. A note about the new snd_hdac_acomp_init() function: there is a slight difference between this and the old snd_hdac_i915_init(). The latter (still) synchronizes with the master component binding, i.e. it assures that the relevant DRM component gets bound when it returns, or gives a negative error. Meanwhile the new function doesn't synchronize but just leaves as is. It's the responsibility by the caller's side to synchronize, or the caller may accept the asynchronous binding on the fly. v1->v2: Fix missing NULL check in master_bind/unbind Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-17ALSA: hda/i915: Associate audio component with devresTakashi Iwai1-2/+4
The HD-audio i915 binding code contains a single pointer, hdac_acomp, for allowing the access to audio component from the master bind/unbind callbacks. This was needed because the callbacks pass only the device pointer and we can't guarantee the object type assigned to the drvdata (which is free for each controller driver implementation). And this implementation will be a problem if we support multiple components for different DRM drivers, not only i915. As a solution, allocate the audio component object via devres and associate it with the given device, so that the component callbacks can refer to it via devres_find(). The removal of the object is still done half-manually via devres_destroy() to make the code consistent (although it may work without the explicit call). Also, the snd_hda_i915_register_notifier() had the reference to hdac_acomp as well. In this patch, the corresponding code is removed by passing hdac_bus object to the function, too.

The i915 specific stuff remains in struct i915_audio_component, which contains drm_audio_component as the base. The license of drm_audio_component.h is kept to MIT as same as the the original i915_component.h. This is a preliminary change for further development, and no functional changes by this patch itself, merely code-split and renames. v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915 argument in drm_audio_component.h Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-07-03ASoC: core: Allow topology to override machine driver FE DAI link config.Liam Girdwood1-0/+13
Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. 5) assign a new card name prefix to differentiate this topology to userspace. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.
