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

More cleanup to i2c autoconfiguration:
- Get all of the drivers onto the new match quality constants.
- Introduce a new helper function, iic_use_direct_match(), that has
all of the logic for direct-config matching. If it returns true,
the driver returns the match result (which may be 0). If it returns
false, the driver does indirect-config matching.
- iic_compat_match() now returns a weighted match quality; matches to
lower-indexed "compatible" device property are more-specific matches,
and return a better match quality accordingly.

Apply WM8731 support patch from TOYOKURA Atsushi, arranged by me.
- SL-C700: work fine
- SL-C750: attach failed
- SL-C860: not tested

isaki | Move dev/audio_if.h -> dev/audio/audio_if.h
|
| 1.2.4.3 |
| 04-May-2019 |
isaki | Remove obsoleted methods in audio_hw_if.
- drain: is handled in audio upper layer now.
- mappage: is handled in audio upper layer now.
- setfd: no one uses and it's meaningless now.
|
| 1.2.4.2 |
| 24-Apr-2019 |
isaki | Adapt zaudio family to audio2.
- wm8731 and wm8750 can share zaudio_formats[].
- Drop INDEPENDENT property. These share sample rate in play and rec.
- pxa2x0_i2s_setspeed() no longer needs to writeback sample rate.
|
| 1.2.4.1 |
| 21-Apr-2019 |
isaki | Use C99 style struct initializer to audio_format.
