RevisionDateAuthorComments
 1.6  20-Dec-2023  thorpej Remove unnecessary <sys/malloc.h>.
 1.5  29-Feb-2020  isaki Remove rounding by 4 bytes on round_blocksize().
For drivers which supports only 16bit * 2channels sampling,
rounding by 4 bytes no longer meaningful.
 1.4  07-Jun-2019  isaki branches: 1.4.4;
Rename uda_ssio_getprops() -> uda_ssio_get_props() to make it easy
to search.
 1.3  08-May-2019  isaki Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
 1.2  16-Mar-2019  isaki branches: 1.2.2;
Use C99 style struct initializer to audio_hw_if.
 1.1  30-Jan-2012  nisimura branches: 1.1.4; 1.1.50;

Add FriendlyARM Mini2440 support.
- new code for Samsung S3C2440 SoC.
- update for other S3C2xx0.
This port was done by Paul Fleischer.
 1.1.50.2  08-Apr-2020  martin Merge changes from current as of 20200406
 1.1.50.1  10-Jun-2019  christos Sync with HEAD
 1.1.4.2  17-Apr-2012  yamt sync with head
 1.1.4.1  30-Jan-2012  yamt file audio_mini2440.c was added on branch yamt-pagecache on 2012-04-17 00:06:15 +0000
 1.2.2.4  04-May-2019  isaki Move dev/audio_if.h -> dev/audio/audio_if.h
 1.2.2.3  04-May-2019  isaki Remove simple flags that indicate whether the device is opened.
These are handled in the upper layer now.
 1.2.2.2  01-May-2019  isaki set_params -> set_format in comment.
 1.2.2.1  25-Apr-2019  isaki Adapt to audio2.
- The sample rate seems to be determined by peripherals so
move uda1341_formats[] structure from ic/uda1341.c to audio_mini2440.c.
- XXX Resetting the device in open() (and close()) might be harmful
but I don't know details about what does this reset do.
 1.4.4.1  29-Feb-2020  ad Sync with head.
