We had again a busy development cycle with many new drivers as well as
lots of core improvements / cleanups. Let's go for highlights:
ALSA core:
- PCM locking scheme was refactored for reducing a global rwlock
- PCM suspend is handled in the device type PM ops now; lots of
explicit calls were reduced by this action
- Cleanups about PCM buffer preallocation calls
- Kill NULL device object in memory allocations
- Lots of procfs API cleanups
ASoC core:
- Support for only powering up channels that are actively being used
- Cleanups / fixes of topology API
ASoC drivers:
- MediaTek BTCVSD for a Bluetooth radio chip, which is the first such
driver we've had upstream!
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers
- Lots of fixes for probing on Intel systems to follow more standard
styles
- A big refresh and cleanup of the Samsung drivers
- New drivers: Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341
and CS35L26, Google ChromeOS embedded controllers, Ingenic JZ4725B,
MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328,
Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM
formatters
ALSA drivers:
- Improvements of Tegra HD-audio controller driver for supporting new
chips
- HD-audio codec quirks for ALC294 S4 resume, ASUS laptop, Chrome
headset button support and Dell workstations
- Improved DSD support on USB-audio
- Quirk for MOTU MicroBook II USB-audio
- Support for Fireface UCX support and Solid State Logic Duende
Classic/Mini

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
