2024-04-29ASoC: doc: dapm: update section "DAPM Widget Events"Luca Ceresoli1-12/+18
The example in this section is not in the kernel sources anymore. Replace it with an up to date code fragment. Reword the initial paragraph.

2024-04-29ASoC: doc: dapm: improve section "Codec/DSP Widget Interconnections"Luca Ceresoli1-11/+8
Improve wording in a few places, cleanup ReST colon syntax, remove space before colon, and remove the "codec" parameter in the parentheses of snd_soc_dapm_new_widgets() (there should be no parameters in the docs, and that function takes a card, not a codec).

2024-04-29ASoC: doc: dapm: describe how widgets and routes are registeredLuca Ceresoli1-2/+36
The small paragraph describing how to register widgets is incomplete (does not mention routes) and mentions snd_soc_dapm_new_control() which is not really used. Moreover it appears as a part of the "Virtual Widgets" subsection. Replace it with a detailed and current description of how widgets and routes are registered, mentioning both static declaration and runtime registration. Also make this a section on its own.

2024-04-29ASoC: doc: dapm: extend initial descrptionLuca Ceresoli2-9/+396
Extend the initial description providing clearer definitions of "widget" and "route", and to stop using the word "component" to mean "widget".

2020-07-22ASoC: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
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.

2020-03-06ASoC: 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.
