Pull sound updates from Takashi Iwai: "This became wide and scattered updates all over the sound tree as diffstat shows: lots of (still ongoing) refactoring works in ASoC, fixes and cleanups caught by static analysis, inclusive term conversions as well as lots of new drivers. Below are highlights: ASoC core: - API cleanups and conversions to the unified mute_stream() call - Simplify I/O helper functions - Use helper macros to retrieve RTD from substreams ASoC drivers: - Lots of fixes and cleanups in Intel ASoC drivers - Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards, nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards, TI J721e EVM ALSA core: - Minor code refacotring for SG-buffer handling HD-audio: - Generalization of mute-LED handling with LED classdev - Intel silent stream support for HDMI - Device-specific fixes: CA0132, Loongson-3 Others: - Usual USB- and HD-audio quirks for various devices - Fixes for echoaudio DMA position handling - Various documents and trivial fixes for sparse warnings - Conversion to adopt inclusive terms" * tag 'sound-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (479 commits) ALSA: pci: delete repeated words in comments ALSA: isa: delete repeated words in comments ALSA: hda/tegra: Add 100us dma stop delay ALSA: hda: Add dma stop delay variable ASoC: hda/tegra: Set buffer alignment to 128 bytes ALSA: seq: oss: Serialize ioctls ALSA: hda/hdmi: Add quirk to force connectivity ALSA: usb-audio: add startech usb audio dock name ALSA: usb-audio: Add support for Lenovo ThinkStation P620 Revert "ALSA: hda: call runtime_allow() for all hda controllers" ALSA: hda/ca0132 - Fix AE-5 microphone selection commands.

ASoC: cros_ec_codec: use sha256() instead of open coding

2020-07-16T11:49:05Z

Now that there's a function that calculates the SHA-256 digest of a buffer in one step, use it instead of sha256_init() + sha256_update() + sha256_final(). Also simplify the code by inlining calculate_sha256() into its caller and switching a debug log statement to use %*phN instead of bin2hex().

ASoC: cros_ec_codec: switch to library API for SHA-256

2020-05-15T10:56:52Z

The CrOS EC codec driver uses SHA-256 explicitly, and not in a performance critical manner, so there is really no point in using the SHASH crypto API here. Let's switch to the library API instead.

ASoC: cros_ec_codec: allocate shash_desc dynamically

2020-05-08T17:52:12Z

The wov_hotword_model_put() function has multiple large variables on its stack, the largest of which is the result of SHASH_DESC_ON_STACK(). In total, this exceeds the warning limit for 32-bit architectures: sound/soc/codecs/cros_ec_codec.c:776:12: error: stack frame size of 1152 bytes in function 'wov_hotword_model_put' [-Werror,-Wframe-larger-than=] The function already has a dynamic crypto_alloc_shash() allocation, so using kmalloc() for the descriptor is correct as well and does not introduce any additional failure scenarios. With this, the stack usage of wov_hotword_model_put() gets reduced to 480 bytes in my test configuration.

Merge tag 'asoc-fix-v5.5-rc6' into asoc-5.6

2020-01-17T15:38:56Z

ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized.
