https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.9 The biggest changes here one again come from Mormioto-san who has continued his dilligent work cleaning up long standing issues in the APIs, it's particularly nice to see the transition from digital_mute() to mute_stream() finally completed. There's also been a lot of work on the x86 code again, this time a big focus has been on cleaning up some issues identified by various static tests, and on the Freescale systems. Otherwise the biggest thing has been a lot of driver additions: - Convert users of digital_mute() to mute_stream(). - Simplify I/O helper functions. - Add a helper for getting the RTD from a substream. - Many, many fixes and cleanups to the x86 code. - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some of the first phones I worked on!) and TI J721e EVM.

2020-03-31ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixupsThomas Hebb1-2/+0
patch_realtek.c has historically failed to properly configure the PC Beep Hidden Register for the ALC256 codec (among others). Depending on your kernel version, symptoms of this misconfiguration can range from chassis noise, picked up by a poorly-shielded PCBEEP trace, getting amplified and played on your internal speaker and/or headphones to loud feedback, which responds to the "Headphone Mic Boost" ALSA control, getting played through your headphones. For details of the problem, see the patch in this series titled "ALSA: hda/realtek - Set principled PC Beep configuration for ALC256", which fixes the configuration. These symptoms have been most noticed on the Dell XPS 13 9350 and 9360, popular laptops that use the ALC256. As a result, several model-specific fixups have been introduced to try and fix the problem, the most egregious of which locks the "Headphone Mic Boost" control as a hack to minimize noise from a feedback loop that shouldn't have been there in the first place. Now that the underlying issue has been fixed, remove all these fixups. Remaining fixups needed by the XPS 13 are all picked up by existing pin quirks. This change should, for the XPS 13 9350/9360 - Significantly increase volume and audio quality on headphones - Eliminate headphone popping on suspend/resume - Allow "Headphone Mic Boost" to be set again, making the headphone jack fully usable as a microphone jack too. Fixes: 8c69729b4439 ("ALSA: hda - Fix headphone noise after Dell XPS 13 resume back from S3") Fixes: 423cd785619a ("ALSA: hda - Fix headphone noise on Dell XPS 13 9360") Fixes: e4c9fd10eb21 ("ALSA: hda - Apply headphone noise quirk for another Dell XPS 13 variant") Fixes: 1099f48457d0 ("ALSA: hda/realtek: Reduce the Headphone static noise on XPS 9350/9360") Cc: stable@vger.kernel.org Signed-off-by: Thomas Hebb <tommyhebb@gmail.com> Link: https://lore.kernel.org/r/b649a00edfde150cf6eebbb4390e15e0c2deb39a.1585584498.git.tommyhebb@gmail.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-03-31ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256Thomas Hebb2-0/+130
This codec (among others) has a hidden set of audio routes, apparently designed to allow PC Beep output without a mixer widget on the output path, which are controlled by an undocumented Realtek vendor register. The default configuration of these routes means that certain inputs aren't accessible, necessitating driver control of the register. However, Realtek has provided no documentation of the register, instead opting to fix issues by providing magic numbers, most of which have been at least somewhat erroneous. These magic numbers then get copied by others into model-specific fixups, leading to a fragmented and buggy set of configurations. To get out of this situation, I've reverse engineered the register by flipping bits and observing how the codec's behavior changes. This commit documents my findings. It does not change any code.

2020-03-06ASoC: simple-card: Add support for codec2codec DAI linksSamuel Holland1-2/+7
Following the example in cb2cf0de1174 ("ASoC: soc-core: care Codec <-> Codec case by non_legacy_dai_naming"), determine if a DAI link contains only codec DAIs by examining the non_legacy_dai_naming flag in each DAI's component. For now, we assume there is only one or a small set of valid PCM stream parameters, so num_params == 1 is good enough. We also assume that the same params are valid for all supported streams. params is set to the subset of parameters common among all DAIs, and then the existing code automatically chooses the highest quality of the remaining values when the link is brought up.

2019-12-17ALSA: cmipci: Allow disabling MPU port via module optionTakashi Iwai1-1/+2
Patrick May reported that his sound card with CMI8378 chip causes a crash / reboot when accessing the MIDI port that isn't actually present on the board. Moreover, despite of the documentation, passing mpu_port=0 doesn't disable the MIDI port on this board. It implies that the chip is a newer revision and the MPU401 port is integrated and mapped on the PCI register. For this chip model, the driver enables the MPU port unconditionally, so far. Although fixing the unexpected reboot would be the best solution, it's not so trivial to identify the cause. So, as a plan B, this patch extends the existing mpu_port option usage to allow disabling the port by specifying the value 0, just like we applied for fm_port option in commit 2f24d159d5ac ("[ALSA] cmipci - Allow to disable integrated FM port"). As default, the MPU port is still enabled, but user can pass mpu_port=0 to disable it.

We've also seen a lot of driver work, a lot of it cleanups but also some particular drivers. - Lots and lots of cleanups from Morimoto-san and Yue Haibing. - Lots of cleanups and enhancements to the Freescale, sunxi dnd Intel rivers. - Initial Sound Open Firmware suppot for i.MX8. - Removal of w90x900 and nuc900 drivers as the platforms are being removed. - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX 7ULP and 8MQ, Meson G12A and NXP UDA1334

2019-08-09ALSA: hda - Add a quirk model for fixing Huawei Matebook X right speakerTomas Espeleta1-0/+3
[ This is rather a revival of the patch Tomas sent in months ago, but applying only with the quirk model option -- tiwai ] Hard coded coefficients to make Huawuei Matebook X right speaker work. The Matebook X has a ALC298, please refer to bug 197801 on how these numbers were reverse engineered from the Windows driver The reversed engineered sequence represents a repeating pattern of verbs, and the only values that are changing periodically are written on indexes 0x23 and 0x25: 0x500, 0x23 0x400, VALUE1 0x500, 0x25 0x400, VALUE2 * skipped reading sequences (0x500 - 0xc00 sequences are ignored) * static values from reverse engineering are used NOTE: since a significant risk is still considered, this is provided as an experimental fix that isn't applied as default for now. For enabling the fix, you'll have to choose huawei-mbx-stereo via model option of snd-hda-intel module. If we get feedback from users that this works stably, we may apply it per default.

2019-02-01ALSA: isa: Avoid passing NULL to memory allocatorsTakashi Iwai1-5/+5
We used to pass NULL to memory allocators for ISA devices due to historical reasons. But we prefer rather a proper device object to be assigned, so let's fix it by replacing snd_dma_isa_data() call with card->dev reference, and kill snd_dma_isa_data() definition.

2018-11-20Documentation: Use "while" instead of "whilst"Will Deacon2-4/+4
Whilst making an unrelated change to some Documentation, Linus sayeth: | Afaik, even in Britain, "whilst" is unusual and considered more | formal, and "while" is the common word. | | [...] | | Can we just admit that we work with computers, and we don't need to | use þe eald Englisc spelling of words that most of the world never | uses? dictionary.com refers to the word as "Chiefly British", which is probably an undesirable attribute for technical documentation. Replace all occurrences under Documentation/ with "while".
