ALSA: hda: Enhance pm_blacklist option

2024-07-30T05:45:55+00:00

We want sometimes to keep the runtime PM disabled persistently just like we did for the PM deny-list in the previous change, e.g. for testing some buggy device. This patch enhances the existing pm_blacklist option for achieving it easily. The default behavior doesn't change -- the driver looks up the deny list and disables the runtime PM if matches. However, when pm_blacklist=1 option is set, now the driver disables the runtime PM completely, just like the deny-list does. Update the documentation for this option, too.

Merge tag 'asoc-v6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-05-13T09:39:49+00:00

ASoC: Updates for v6.10 This is a very big update, in large part due to extensive work the Intel people have been doing in their drivers though it's also been busy elsewhere. There's also a big overhaul of the DAPM documentation from Luca Ceresoli arising from the work he did putting together his recent ELC talk, and he also contributed a new tool for visualising the DAPM state. - A new tool dapm-graph for visualising the DAPM state. - Substantial fixes and clarifications for the DAPM documentation. - Very large updates throughout the Intel audio drivers. - Cleanups of accessors for driver data, module labelling, and for constification. - Modernsation and cleanup work in the Mediatek drivers. - Several fixes and features for the DaVinci I2S driver. - New drivers for several AMD and Intel platforms, Nuvoton NAU8325, Rockchip RK3308 and Texas Instruments PCM6240.

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).
