Also drop the unnecessary check at the beginning of the uda1380_set_bias_level() which compares the current level to the target level and aborts if they are the same. Since the core will not call the set_bias_level() callback if we already are in the target state the result of the check is always false.

2015-05-11ASoC: dapm: Break out of widget search when source and sink are locatedCharles Keepax1-2/+8
Currently snd_soc_dapm_add_route will continue to search the widget list even after both the source and sink for the route have been located.

2015-05-08ASoC: dapm: Add missing mutex unlockCharles Keepax1-1/+3
The is a missing mutex unlock on the error path in snd_soc_dapm_get_enum_double. This was introduced in commit 561ed680b764 ("ASoC: dapm: Add support for autodisable mux controls").

2015-05-06ASoC: dapm: Add demux supportLars-Peter Clausen1-15/+97
A demux is conceptually similar to a mux. Where a mux has multiple input and one output and selects one of the inputs to be connected to the output, the demux has one input and multiple outputs and selects one of the outputs to which the input gets connected. This similarity makes it straight forward to support them in DAPM using the existing mux support, we only need to swap sinks and sources when initially setting up the paths. The only slightly tricky part is that there can only be one control per path. Since mixers/muxes are at the sink of a path and a demux is at the source and both types want a control it is not possible to directly connect a demux output to a mixer/mux input. The patch adds some sanity checks to make sure that this does not happen. Drivers who want to model hardware which directly connects a demux output to a mixer/mux input can do this by inserting a dummy widget between the two. E.g.: { "Dummy", "Demux Control", "Demux" }, { "Mixer", "Mixer Control", "Dummy" }, Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-05-06ASoC: dapm: Add new widgets to the end of the widget listLars-Peter Clausen1-1/+1
Currently new widgets are appended to the beginning of the cards widget list. This has the effect that widgets that are created while iterating over the widget list in snd_soc_dapm_new_widgets() (like e.g. the auto-disable widgets) are not covered during that invocation of the function. If no further invocations of snd_soc_dapm_new_widgets() happen these widgets will not be fully initialized and e.g. no debugfs entries are created for them. By adding new widgets to the end of the widget list we make sure that widgets that are created in snd_soc_dapm_new_widgets() will still be handled during the same snd_soc_dapm_new_widgets() invocation and are always fully initialized.

2015-05-06ASoC: dapm: Add support for autodisable mux controlsCharles Keepax1-19/+59
Commit 57295073b6ac ("ASoC: dapm: Implement mixer input auto-disable") added support for autodisable controls, controls whose values are only written to the hardware when their respective widgets are powered up. But it only added support for controls based on the mixer abstraction. This patch add support for mux controls (DAPM controls based on the enum abstraction) to be auto-disabled as well. As each mux can only have a single control, there is no need to tie the autodisable widget to the inputs (as is done for the mixer controls) it can be tided directly to the mux widget itself. Note that it is assumed that the first entry in a autodisable mux control will always represent the off state for the mux and is what the mux will be set to whilst it is disabled.

This makes it a little easier to follow what is happening in debugfs. Additionally is also useful in facilitating work to add autodisable muxes because the control name is already used for the mux widget and thus shouldn't be reused for the autodisable widget.

Use the new snd_soc_codec_force_bias_level() helper function to invoke the bias_level callback of a driver instead of calling the callback by hand. Currently the effect of this is the same, but having all bias level updates go through a central place will allow us to move more of the bias level management into the DAPM core.

2015-04-27ASoC: Add helper functions bias level managementLars-Peter Clausen1-4/+31
Currently drivers are responsible for managing the bias_level field of their DAPM context. The DAPM state itself is managed by the DAPM core though and the core has certain expectations on how and when the bias_level field should be updated. If drivers don't adhere to these undefined behavior can occur. This patch adds a few helper functions for manipulating the DAPM context state, each function with a description on when it should be used and what its effects are. This will also help us to move more of the bias_level management from drivers to the DAPM core. For convenience also add snd_soc_codec_* wrappers around these helpers.

The ALC256 does not have a mixer nid at 0x0b, and there's no loopback path (the output pins are directly connected to the DACs). This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)" error (and as a result, problems with amixer/alsamixer). If there's pcbeep functionality, it certainly isn't controlled by setting an amp on 0x0b, so disable beep functionality (at least for now).

2015-04-21ALSA: usb-audio: Fix audio output on Roland SC-D70 sound moduleTakamichi Horikawa2-29/+6
Roland SC-D70 reports its device class as vendor specific class and the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output. In the quirks table the sampling rate was hard-coded to 44100 Hz and therefore not worked when the sound module was in 48000 Hz mode. In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE but as the sound module reports incorrect bSubframeSize in its descriptors, additional change is made in format.c to detect it and to override it (which uses the existing code for Edirol SD-90). Tested both when the sound module was in 44100 Hz mode and 48000 Hz mode and both audio input and output. MIDI related part of the driver is not touched.

2015-04-21ALSA: hda - add AZX_DCAPS_I915_POWERWELL to BaytrailMengdong Lin1-1/+4
This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-18sound/oss: fix deadlock in sequencer_ioctl(SNDCTL_SEQ_OUTOFBAND)Alexey Khoroshilov1-10/+2
A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND) on /dev/sequencer with TMR_ECHO midi event. In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There have been major modernization with the standard bus: in ALSA sequencer core and HD-audio. Also, HD-audio receives the regmap support replacing the in-house cache register cache code. These changes shouldn't impact the existing behavior, but rather refactoring. In addition, HD-audio got the code split to a core library part and the "legacy" driver parts. This is a preliminary work for adapting the upcoming ASoC HD-audio driver, and the whole transition is still work in progress, likely finished in 4.1. Along with them, there are many updates in ASoC area as usual, too: lots of cleanups, Intel code shuffling, etc. Here are some highlights: ALSA core: - PCM: the audio timestamp / wallclock enhancement - PCM: fixes in DPCM management - Fixes / cleanups of user-space control element management - Sequencer: modernization using the standard bus HD-audio: - Modernization using the standard bus - Regmap support - Use standard runtime PM for codec power saving - Widget-path based power-saving for IDT, VIA and Realtek codecs - Reorganized sysfs entries for each codec object - More Dell headset support ASoC: - Move of jack registration to the card level - Lots of ASoC cleanups, mainly moving things from the CODEC level to the card level - Support for DAPM routes specified by both the machine driver and DT - Continuing improvements to rcar - pcm512x enhacements - Intel platforms updates - rt5670 updates / fixes - New platforms / devices: some non-DSP Qualcomm platforms, Google's Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC Misc: - ice1724: Improved ESI W192M support - emu10k1: Emu 1010 fixes/enhancement" * tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) ALSA: hda - set GET bit when adding a vendor verb to the codec regmap ALSA: hda/realtek - Enable the ALC292 dock fixup on the Thinkpad T450 ALSA: hda - Fix another race in runtime PM refcounting ALSA: hda - Expose codec type sysfs ALSA: ctl: fix to handle several elements added by one operation for userspace element ASoC: Intel: fix array_size.cocci warnings ASoC: n810: Automatically disconnect non-connected pins ASoC: n810: Consistently pass the card DAPM context to n810_ext_control() ASoC: davinci-evm: Use card DAPM context to access widgets ASoC: mop500_ab8500: Use card DAPM context to access widgets ASoC: wm1133-ev1: Use card DAPM context to access widgets ASoC: atmel: Improve machine driver compile test coverage ASoC: atmel: Add dependency to SND_SOC_I2C_AND_SPI where necessary ALSA: control: Fix a typo of SNDRV_CTL_ELEM_ACCESS_TLV_* with SNDRV_CTL_TLV_OP_* ALSA: usb-audio: Don't attempt to get Microsoft Lifecam Cinema sample rate ASoC: rnsd: fix build regression without CONFIG_OF ALSA: emu10k1: add toggles for E-mu 1010 optical ports ALSA: ctl: fill identical information to return value when adding userspace elements ALSA: ctl: fix a bug to return no identical information in info operation for userspace controls ALSA: ctl: confirm to return all identical information in 'activate' event ...

2015-04-14ALSA: hda - set GET bit when adding a vendor verb to the codec regmapMengdong Lin1-1/+1
Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11) when adding the verb so that its peer vendor 'get' verb is actually added. This can avoid I/O error when writing the 'set' verb thru remap, since HD-A regmap internally looks up a writable vendor verb with GET bit set at first.

2015-04-13ALSA: hda - Fix another race in runtime PM refcountingTakashi Iwai1-0/+30
Although some races in runtime PM refcount was fixed by the commit [664c715573c2: ALSA: hda - Work around races of power up/down with runtime PM], there is still a race in the following case: CPU0: CPU1 : runtime suspend: codec->in_pm = 1 snd_hdac_power_up_pm(): pm_runtime_get_sync() skipped suspend finished: codec->in_pm = 0 snd_hdac_power_down_pm(): pm_runtime_put_*() is called! For avoiding this situation, increment in_pm flag atomically when it's non-zero, and decrement accordingly, to ensure that in_pm is set consistently for the whole concurrent operations. Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm() to sound/hda/hdac_device.c as no inline functions.
