* ALSA: doc: Drop snd_dma_continuous_data() usagesTakashi Iwai2022-08-241-13/+8
| | | | | | | | | | Update the documentation to follow the recent change of the memory allocation helpers. The macro snd_dma_continuous_data() is gone, and the driver needs to set up the coherent dma mask for allocating in the lower memory addresses, instead.

* ALSA: doc: Clarify IEC958 controls ifaceMaxime Ripard2021-06-081-6/+7
| | | | | | | | | | | | | | | | The doc currently mentions that the IEC958 Playback Default should be exposed on the PCM iface, and the Playback Mask on the mixer iface. It's a bit confusing to advise to have two related controls on two separate ifaces, and it looks like the drivers that currently expose those controls use any combination of the mixer and PCM ifaces. Let's try to clarify the situation a bit, and encourage to at least have the controls on the same iface.

* docs: Fix reST markup when linking to sectionsNícolas F. R. A. Prado2020-12-311-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the process of converting the documentation to reST, some links were converted using the following wrong syntax (and sometimes using %20 instead of spaces): `Display text <#section-name-in-html>`__ This syntax isn't valid according to the docutils' spec [1], but more importantly, it is specific to HTML, since it uses '#' to link to an HTML anchor. The right syntax would instead use a docutils hyperlink reference as the embedded URI to point to the section [2], that is: `Display text <Section Name_>`__ This syntax works in both HTML and PDF. The LaTeX toolchain doesn't mind the HTML anchor syntax when generating the pdf documentation (make pdfdocs), that is, the build succeeds but the links don't work, but that syntax causes errors when trying to build using the not-yet-merged rst2pdf: ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States' So, use the correct syntax in order to have it work in all different output formats.

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.

| | | | | | | | | | | | | | Currently we pass the artificial device pointer to the allocation helper in the case of SNDRV_DMA_TYPE_CONTINUOUS for passing the GFP flags. But all common cases are the allocations with GFP_KERNEL, and it's messy to put this in each place. In this patch, the memalloc core helper is changed to accept the NULL device pointer and it treats as the default mode, GFP_KERNEL, so that all callers can omit the complex argument but just leave NULL.
