ALSA: hda: cirrus_scodec: Add KUnit test Add a KUnit test for cirrus_scodec_get_speaker_id(). It is impractical to have enough hardware with every possible permutation of speaker id. So use a test harness to test all theoretically supported options. The test harness consists of: - a mock GPIO controller. - a mock struct device to represent the scodec driver - software nodes to provide the fwnode info that would normally come from ACPI.

ALSA: hda: cs35l56: Add support for speaker id Add handling of the "spk-id-gpios" _DSD property. If present, the value indicated by the GPIOs is appended to the subsystem-id part of the firmware name to load the appropriate tunings for that speaker. Some manufacturers use multiple sources of speakers, which need different tunings for best performance. On these models the type of speaker fitted is indicated by the values of one or more GPIOs. The number formed by the GPIOs identifies the tuning required. The speaker ID is only used in combination with a _SUB identifier because the value is only meaningful if the exact model is known. The code to get the speaker ID value has been implemented as a new library so that the cs35l41_hda driver can be switched in future to share common code. This library can be extended for other common functionality shared by Cirrus Logic amp drivers.

ALSA: hda/cs35l56: Add driver for Cirrus Logic CS35L56 amplifier Add a driver for the Cirrus Logic CS35L56 amplifier. This uses the same component binding API as the CS35L41 driver. This is not a standalone HDA device; it provides control of the CS35L56 for systems that use a combination of an HDA codec and CS35L56 amplifiers with audio routed through the HDA codec. The CS35L56 combines a high-performance mono audio amplifier, Class-H tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost converter supporting Class-H tracking. Control interfaces are I2C or SPI through the standard Linux I2C or SPI bus framework. Most chip functionality is controlled by on-board ROM firmware that is always running. Firmware patches can be applied by the driver in the form of a .wmfw file (firmware patch) and/or a .bin file (system tuning).

License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

ALSA: hda - Bind codecs via standard bus Now we create the standard HD-audio bus (/sys/bus/hdaudio), and bind the codec driver with the codec device over there. This is the first step of the whole transition so that the changes to each codec driver are kept as minimal as possible. Each codec driver needs to register hda_codec_driver struct containing the currently existing preset via the new helper macro module_hda_codec_driver(). The old hda_codec_preset_list is replaced with this infrastructure. The generic parsers (for HDMI and other) are also included in the preset with the special IDs to bind uniquely. In HD-audio core side, the device binding code is split to hda_bind.c. It provides the snd_hda_bus_type implementation to match the codec driver with the given codec vendor ID. It also manages the module auto-loading by itself like before: when the matching isn't found, it tries to probe the corresponding codec modules, and finally falls back to the generic drivers. (The special ID mentioned above is set at this stage.) The only visible change to outside is that the hdaudio sysfs entry now appears in /sys/bus/devices, not as a sound class device. More works to move the suspend/resume and remove ops will be (hopefully) done in later patches. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Make CONFIG_SND_HDA_CODEC_* tristate So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to historical reasons. The major reason was that the automatic codec driver probing wouldn't work if user sets a codec driver as a module while the controller driver as a built-in. And, another reason was to avoid exporting symbols of the helper codes when all drivers are built in. But, this sort of "kindness" rather confuses people in the end, especially makes the config refinement via localmodconfig unhappy. Also, a codec module would still work if you re-bind the controller driver via sysfs (although it's no automatic loading), so there might be a slight use case. That said, better to let people fallen into a pitfall than being too smart and restrict something. Let's make things straightforward: now all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported unconditionally. Signed-off-by: Takashi Iwai <tiwai@suse.de>

When the unsol event is enabled via snd_hda_jack_detect_enable(), it automatically adds the given NID to the table. Then the driver supposes that the codec driver will set the dirty flag appropariately when an unsolicited event is invoked for that pin. The behavior for reading other pins that aren't registered in the table doesn't change. Only the pins assigned to the table are cached, so far. In near futre, this table can be extended to use the central place for the unsolicited events of all pins, etc, and eventually include the jack-detect kcontrols that replace the current input-jack stuff.

ALSA: hda - Modularize HD-audio driver Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers. TODO: - Avoid EXPORT_SYMBOL*() when built-in kernel - Restore __devinit appropriately depending on the condition Signed-off-by: Takashi Iwai <tiwai@suse.de>

[ALSA] Keep private TLV entry in vmaster itself Use a private array for TLV entries of virtual master controls instead of (supposed) static array. This cleans up the existing codes. Also, now vmaster assumes the simple dB-range TLV that is the only type it can handle. Signed-off-by: Takashi Iwai <tiwai@suse.de>

[ALSA] Add virtual master control helpers Added helper functions to implement virtual master volume controls. The virtual master control is a control element that has multiple slave controls. The value of master element is equally added to slave elements. The functions are written for general purpose, but it's put in the HD-audio directory as now, since HD-audio driver is the only user. It should be moved to the common place once after other drivers use vmaster. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

Although hda-codec stuff is designed to be used universally from different controller drivers, currently only one controller interface (and compatibles) are used. So, let's merge them to a single module to save memory. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

[ALSA] add sigmatel codec support HDA generic driver,HDA Codec driver Add initial SigmaTel codec support for 9200 and 922x. Note that this hda patch relies on the configuration default registers to be set correctly (normally by BIOS/firmware) in order for it to set up pin widgets properly. There's a test switch in the patch so it will work with the SigmaTel reference boards that are usually plugged into a system that doesn't set the configuration default registers. It supports 2 channel analog out and line/mic in. I plan to add >2 channel support and spdif support shortly. Please apply.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
