Merge tag 'sound-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There are no big surprising changes in this cycle, yet not too boring, either. The biggest change from diffstat POV is the removal of the legacy OSS driver codes that have been already disabled for a long time. This will bring a few trivial merge conflicts. As new features in ASoC side, there are two things: a new AC97 bus implementation and AMD Stony platform support. Both include the relevant changes shared with other subsystems, e.g. AC97 MFD changes and DRM AMD changes. Some other highlighted topics are: - A bunch of USB-audio drivers got the hardening against the malicious device accesses with a new helper code for endpoint sanity check - Lots of cleanups for ASoC Intel platform code, including support for their open source audio firmware - Continued ASoC core componentization works - Support for scaling MCLK with sample rate in ASoC simple-card - Stabler PCM hot-unplug capability, especially for ASoC usages" * tag 'sound-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (302 commits) Documentation: sound: hd-audio: notes.rst ASoC: bcm2835: Support left/right justified and DSP modes ASoC: bcm2835: Enforce full symmetry ASoC: bcm2835: Support additional samplerates up to 384kHz ASoC: bcm2835: Add support for TDM modes ASoC: add mclk-fs support to audio graph card ASoC: add mclk-fs to audio graph card binding ASoC: rt5514: work around link error ASoC: rt5514: mark PM functions as __maybe_unused ASoC: rt5663: Check the JD status in the button pushing ASoC: amd: Modified DMA transfer Mechanism for Playback ASoC: rt5645: Wait for 400msec before concluding on value of RT5645_VENDOR_ID2 ASoC: sun4i-codec: fixed 32bit audio capture support for H3/H2+ ASoC: da7213: add support for DSP modes ASoC: sun8i-codec: Add a comment on the LRCK inversion ASoC: sun8i-codec: Set the BCLK divider ASoC: rt5663: Delay and retry reading rt5663 ID register ASoC: amd: use do_div rather than 64 bit division to fix 32 bit builds ASoC: cs42l56: Fix reset GPIO name in example DT binding ASoC: rt5514-spi: check irq status to schedule data copy in resume function ...
