Merge tag 'sound-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There've been many updates in ASoC side at this time, especially the framework enhancement for multiple CODECs on a single DAI and more componentization works. The only major change in ALSA core is the addition of timestamp type in sw_params field. This should behave in backward compatible way. Other than that, there are lots of small changes and new drivers in wide range, including a large code cut in HD-audio driver for deprecated static quirks. Some highlights are below: ALSA Core: - Add the new timestamp type field to sw_params to choose MONOTONIC_RAW type HD-audio: - Continued conversion to standard printk macros, generic code cleanups - Removal of obsoleted static quirk codes for Conexant and C-Media codecs - Fixups for HP Envy TS, Dell XPS 15, HP and Dell mute/mic LED, Gigabyte BXBT-2807 mobo - Intel Braswell support ASoC: - Support for multiple CODECs attached to a single DAI, enabling systems with for example multiple DAC/speaker drivers on a single link, contributed by Benoit Cousson based on work from Misael Lopez Cruz - Support for byte controls larger than 256 bytes based on the use of TLVs contributed by Omair Mohammed Abdullah - More componentisation work from Lars-Peter Clausen - The remainder of the conversions of CODEC drivers to params_width() by Mark Brown - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments TAS2552 - Lots of updates and fixes, especially to the DaVinci, Intel, Freescale, Realtek, and rcar drivers" * tag 'sound-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (402 commits) ALSA: usb-audio: Whitespace cleanups for sound/usb/midi.* ALSA: usb-audio: Respond to suspend and resume callbacks for MIDI input sound/oss/pss: Remove typedefs pss_mixerdata and pss_confdata sound/oss/opl3: Remove typedef opl_devinfo ALSA: fireworks: fix specifiers in format strings for propper output ASoC: imx-audmux: Use uintptr_t for port numbers ASoC: davinci: Enable menuconfig entry for McASP ASoC: fsl_asrc: Don't access members of config before checking it ASoC: fsl_sarc_dma: Check pair before using it ASoC: adau1977: Fix truncation warning on 64 bit architectures ALSA: virtuoso: add Xonar Essence STX II support ALSA: riptide: fix %d confusingly prefixed with 0x in format strings ALSA: fireworks: fix %d confusingly prefixed with 0x in format strings ALSA: hda - add codec ID for Braswell display audio codec ALSA: hda - add PCI IDs for Intel Braswell ALSA: usb-audio: Adjust Gamecom 780 volume level ALSA: usb-audio: improve dmesg source grepability ASoC: rt5670: Fix duplicate const warnings ASoC: rt5670: Staticise non-exported symbols ASoC: Intel: update stream only on stream IPC msgs ...
