Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-01-21ASoC: cirrus: ep93xx-i2s: move .suspend/.resume to componentKuninori Morimoto1-8/+8
There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. This patch moves DAI driver .suspend/.resume to Component driver Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87a76jym4p.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

2018-05-11ASoC: cirrus: i2s: IRQ-based stream watchdogAlexander Sverdlin2-0/+85
I2S controller on EP93xx seems to have undocumented HW issue. According to "EP93xx User’s Guide", controller can handle underflow and either transmit last sample or zeroes in such case until FIFO is filled again. In reality undeflow conditions seem to confuse internal state machine from time to time and the whole stream gets shifted by one byte (as captured by logic analyser on the I2S outputs). One could only hear noise instead of original stream and this continues until the FIFO is disabled and enabled again. Work this around by watching underflow interrupt and resetting I2S TX channel + fill FIFO with zero samples until DMA catches up again. This is a nasty workaround, but it works. Hence, Kconfig option to disable it in case of problems. Signed-off-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
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.

2015-04-27ASoC: dmaengine_pcm: Make FLAG_NO_RESIDUE internalLars-Peter Clausen1-1/+0
Whether residue can be reported or not is not a property of the audio controller but of the DMA controller. The FLAG_NO_RESIDUE was initially added when the DMAengine framework had no support for describing the residue reporting capabilities of the controller. Support for this was added quite a while ago and recently the DMAengine framework started to complain if a driver does not describe its capabilities and a lot of patches have been merged that add support for this where it was missing. So it should be safe to assume that driver on actively used platforms properly implement the DMA capabilities API. This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio controller drivers to manually set the flag. If a DMA driver against expectations does not support reporting its capabilities for now the generic DMAengine PCM driver will now emit a warning and simply assume that residue reporting is not supported. In the future this might be changed to aborting with an error. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

This causes the core to suspend the DAI after the CODEC and resume it before the CODEC so communication to the CODEC is still possible. This is not necessarily something that is specific to AC'97 and can be used by other buses with the same requirement. This patch renames the flag from ac97_control to bus_control to make this explicit. While we are at it also change the type from int to bool. The following semantich patch was used for automatic conversion of the drivers: // <smpl> @@ identifier drv; @@ struct snd_soc_dai_driver drv = { - .ac97_control + .bus_control = - 1 + true }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-10-20ASoC: cs4271: Split SPI and I2C code into different modulesAxel Lin1-1/+2
Currently the cs4271 driver depends on SND_SOC_I2C_AND_SPI. So the driver cannot be built as built-in if CONFIG_I2C=m. Split SPI and I2C code into different modules to avoid this issue.

2014-03-13ASoC: snappercl15: Convert to table based DAPM setupLars-Peter Clausen1-13/+5
Use table based setup to register the DAPM widgets and routes. This on one hand makes the code a bit shorter and cleaner and on the other hand the board level DAPM elements get registered in the card's DAPM context rather than in the CODEC's DAPM context.

2013-12-30ASoC: ep93xx: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen1-9/+0
The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

2013-12-18ASoC: ep93xx: remove custom DMA alloc compat functionStephen Warren3-17/+22
ep93xx_compat_request_channel() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the ep93xx DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().

2013-12-18ASoC: ep93xx: get rid of ep93xx-pcm-audio struct deviceStephen Warren7-17/+46
Modify the ep93xx PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device.

2013-10-23ASoC: ep93xx: Open code dma channel requestMark Brown1-0/+13
Currently the ep93xx DMA code is one of the few users relying on the fact that the compat code uses the dma_data as the filter data for non-DT channel requests. Since the rest of the core expects this to be a struct snd_dmaengine_dai_data this isn't terribly helpful this will be changed to use the already existing filter data so avoid breaking ep93xx by open coding the current behaviour.
