Merge tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"There have been lots of changes in ALSA core, HD-audio and ASoC, also
most of PCI drivers touched by conversions of printks. All these
resulted in a high volume and wide ranged patch sets in this release.
Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new
snd_card_new() function is introduced for that, and all drivers
have been converted.
- Simplification in the device management code in ALSA core; now
managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now; the old static
code still remains in case of regressions. Some old quirks have
been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the
formerly hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a
separate module, ane make a helper module for the generic
controller driver. This is a preliminary change for supporting
Tegra HDMI controller in near future, which slipped from 3.15
merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather
than a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface
drivers rather than having them all in one file helping avoid
dependency issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the
Renesas rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio
driver; the device with boot quirks have been little tested, which
we need to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!); it's still pretty
partial support, only for M-Audio devices"
