sound updates for 4.20
There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

The ALSA drivers are provided in two ways.
|
||||
|
||||
One is the trees provided as a tarball or via cvs from the ALSA's ftp
|
||||
site, and another is the 2.6 (or later) Linux kernel tree. To
|
||||
synchronize both, the ALSA driver tree is split into two different
|
||||
trees: alsa-kernel and alsa-driver. The former contains purely the
|
||||
source code for the Linux 2.6 (or later) tree. This tree is designed
|
||||
only for compilation on 2.6 or later environment. The latter,
|
||||
alsa-driver, contains many subtle files for compiling ALSA drivers
|
||||
outside of the Linux kernel tree, wrapper functions for older 2.2 and
|
||||
2.4 kernels, to adapt the latest kernel API, and additional drivers
|
||||
which are still in development or in tests. The drivers in alsa-driver
|
||||
tree will be moved to alsa-kernel (and eventually to the 2.6 kernel
|
||||
tree) when they are finished and confirmed to work fine.
|
