Merge tag 'sound-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "It was a relatively calm development cycle, and no scaring changes are seen in both core and driver sides. Here are some highlights: ASoC: - A new API for hooking up jacks more generically and easily - Card longname is set based on DMI for a unique UCM profile - Lots of Intel driver fixes: Atom, Broxton, Skylake and newer chips - New drivers for Cirrus CS35L35, DIO DIO2125, Everest ES7132, HiSilicon hi6210, Maxim MAX98927, MT2701 systems with WM8960, Nuvoton NAU8824, Odroid systems, ST STM32 SAI controllers and x86 systems with DA7213 HD-audio: - Many new quirks to support headset for various devices (mostly ASUS ones) as usual - Support for dual codecs on some Gigabyte mobos and Lenovo laptop - Improvement on PCM position reporting for Skylake and newer FireWire: - New drivers for MOTU and RME Fireface series - Updates for Digidesign Digi00x and TASCAM series - Support for tracepoints Others: - USB-audio: improved support for quirk_alias option - Cleanups, constification allover the places" * tag 'sound-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (299 commits) ASoC: codec: wm8960: Relax bit clock computation when using PLL ASoC: codec: wm9860: avoid maybe-uninitialized warning ASoC: nau8824: leave Class D gain at chip default ASoC: nau8824: rename controls to match DAPM controls ASoC: Intel: Skylake: Return negative error code ASoC: Intel: Skylake: Fix unused variable warning ASoC: Intel: Skylake: fix uninitialized pointer use ASoC: sti: Fix error handling if of_clk_get() fails ASoC: cs4271: configure reset GPIO as output ASoC: dwc: Disallow building designware_pcm as a module ALSA: ali5451: fix spelling mistake in "ali_capture_preapre" ASoC: stm32: add SAI driver ASoC: stm32: add bindings for SAI ASoC: Intel: Skylake: Add loadable module support on KBL platform ASoC: Intel: Skylake: Modify load_lib_ipc arguments for a nowait version ASoC: Intel: Skylake: Register dsp_fw_ops for kabylake ASoC: Intel: Skylake: Modify arguments to reuse module transfer function ASoC: Intel: Skylake: Commonize library load ASoC: Intel: Skylake: Move sst common initialization to a helper function ASoC: nau8824: new driver ...
