As diffstat shows we've had again a lot of works done for this cycle:
majority of changes are the continued componentization and code
refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI;
some ioctls have been extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers;
the API itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers;
now including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers

ioremap has provided non-cached semantics by default since the Linux 2.6

The reference to snd_info_entry_ops is rather read-only, so declare it
as a const pointer. This allows a bit more optimization.
There should be no functional changes by this patch.

Update the documentation for the newly introduced managed buffer
allocation mode accordingly. The old preallocation is no longer
recommended.

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.

chip->ioport is dereferenced in two places, but the struct is
defined as follows:

struct pci_dev *pci;
unsigned long port;

We used to pass NULL to memory allocators for ISA devices due to
historical reasons. But we prefer rather a proper device object to be
assigned, so let's fix it by replacing snd_dma_isa_data() call with
card->dev reference, and kill snd_dma_isa_data() definition.

The PCM suspend procedure was changed for drivers, so that they don't
have to call snd_pcm_suspend*() in each callback any longer. Update
the documentation to adapt the changes.

Slightly brushing up and throw the old dust away from my ancient
writing-an-alsa-driver document. The contents aren't changed so much
but the obsoleted parts are dropped.
Also, remove the date and the version number. It's useless.

Another simple conversion from DocBook to ReST.
This required a few manual fixups and reformats, but the most of

A simple conversion of alsa-driver-api document from DocBook to ReST.
It's moved to the new Documentation/sound/kernel-api subdirectory that
will contain other ALSA kernel API documents.
The GPL legal note was removed, as it's superfluous (and doesn't fit
with ReST kernel docs pretty well).
