Merge tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There are little changes in core part, but lots of development are found in drivers, especially ASoC. The diffstat shows regmap-related changes for a slight API additions / changes, and that's all. Looking at the code size statistics, the most significant addition is for Intel Skylake. (Note that SKL support is still underway, the codec driver is missing.) Also STI controller driver is a major addition as well as a few new codec drivers. In HD-audio side, there are fewer changes than the past. The noticeable change is the support of ELD notification from i915 graphics driver. Thus this pull request carries a few changes in drm/i915. Other than that, USB-audio got a rewrite of runtime PM code. It was initiated by lockdep warning, but resulted in a good cleanup in the end. Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier" * tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) drm/i915: Add locks around audio component bind/unbind drm/i915: Drop port_mst_index parameter from pin/eld callback ALSA: hda - Fix missing inline for dummy snd_hdac_set_codec_wakeup() ALSA: hda - Wake the codec up on pin/ELD notify events ALSA: hda - allow codecs to access the i915 pin/ELD callback drm/i915: Call audio pin/ELD notify function drm/i915: Add audio pin sense / ELD callback ASoC: zx296702-i2s: Fix resource leak when unload module ASoC: sti_uniperif: Ensure component is unregistered when unload module ASoC: au1x: psc-i2s: Convert to use devm_ioremap_resource ASoC: sh: dma-sh7760: Convert to devm_snd_soc_register_platform ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leak ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc failure ASoC: Clean up docbook warnings ASoC: txx9: Convert to devm_snd_soc_register_platform ASoC: pxa: Convert to devm_snd_soc_register_platform ASoC: nuc900: Convert to devm_snd_soc_register_platform ASoC: blackfin: Convert to devm_snd_soc_register_platform ASoC: au1x: Convert to devm_snd_soc_register_platform ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops ...
