git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat scatters over the tree, we've got many tree-wide small changes, but also got quite a few intrusive changes in the core side. The only ABI-visible core change is the new rawmidi framing mode support while others are kernel-internal, mostly code refactoring and/or nice improvements. Here are some highlights: Core: - A new framing access mode for rawmidi to get timestamps - Cleanup / refactoring of buffer memory management helper code - Support for automatic negotiation of ASoC DAI formats - Revival of software suspend for PCM and control core, as a preliminary work for PCI BAR rescan support ASoC: - Accessory detection support for several Qualcomm parts - Support for IEC958 control with hdmi-codec - Merging of Tegra machine drivers into a single driver - Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm Quinary MI2S, Texas Instruments TAS2505 USB-audio: - Reduction of latency at playback start - Code cleanup / fixes of usx2y driver - Scarlett2 mixer code fixes and enhancements - Quirks for Ozone and Denon devices HD-audio: - A few quirks for HP and ASUS machines - Display power management fixes Others: - FireWire code refactoring and enhancements - Tree-wide trivial coding-style fixes" * tag 'sound-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (594 commits) ALSA: usb-audio: scarlett2: Fix for loop increment in scarlett2_usb_get_config ALSA: hda/realtek: fix mute/micmute LEDs for HP ProBook 630 G8 ALSA: hda/realtek: fix mute/micmute LEDs for HP ProBook 445 G8 ALSA: hda/realtek: fix mute/micmute LEDs for HP ProBook 450 G8 ALSA: hda/realtek - Add ALC285 HP init procedure ALSA: hda/realtek - Add type for ALC287 ALSA: scarlett2: Fix scarlett2_*_ctl_put() return values again ALSA: scarlett2: Fix pad count for 18i8 Gen 3 ALSA: hda/realtek: fix mute/micmute LEDs for HP EliteBook 830 G8 Notebook PC ALSA: firewire-lib: Fix 'amdtp_domain_start()' when no AMDTP_OUT_STREAM stream is found ASoC: qcom: lpass-cpu: mark IRQ_CLEAR register as volatile and readable ALSA: hda: Release codec display power during shutdown/reboot ALSA: hda: Release controller display power during shutdown/reboot ALSA: hda/realtek: Apply LED fixup for HP Dragonfly G1, too ASoC: fsl: remove unnecessary oom message ASoC: tlv320aic32x4: dt-bindings: add TAS2505 to compatible ASoC: tlv320aic32x4: add support for TAS2505 ASoC: tlv320aic32x4: add type to device private data struct ASoC: tegra30: ahub: Use devm_platform_get_and_ioremap_resource() ASoC: tegra: tegra210_admaif: Use devm_platform_get_and_ioremap_resource() ...

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary.

Previously this check activated PIO mode but currently dma_request_chan returns either a valid channel or -EPROBE_DEFER. In order to activate PIO mode check instead if the interrupt line is declared. This reflects better what is documented in the DT bindings (see Documentation/devicetree/bindings/sound/ designware-i2s.txt).

The dw_configure_dai_by_dt() function and further dev->{play,capture} _dma_data.dt data structures seem to be used in this driver only in case of a system using devicetree, thus chan_name assignments have no effect since they will be ignored in dmaengine_pcm_request_chan_of() call and will be substituted with values taken form dmaengine_pcm_dma_channel_names[] table ("tx", "rx"). Also there is no any "TX", "RX" dma-names entries in arch/arm/boot/dts, only lower case "tx", "rx" seem to be used. Lastly, this driver doesn't set SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag when registering a dmaengine PCM to indicate the chan_name should be used. My intention is to eventually remove the struct snd_dmaengine_dai_dma_data chan_name field as there is also a chan_names[] field in struct snd_dmaengine_pcm_config which can be used for same purpose.

2015-10-02ASoC: dwc: fix dma stop transferring issueyitian1-3/+12
Designware I2S uses tx empty and rx available signals as the DMA handshaking signals. during music playing, if XRUN occurs, i2s_stop() function will be executed and both tx and rx irq are masked, when music continues to be played, i2s_start() is executed but both tx and rx irq are not unmasked which cause I2S stop sending DMA handshaking signal to DMA controller, and it finally causes music playing will be stopped once XRUN occurs for the first time. [On list discussion suggests this may be partly a race condition on slow systems -- broonie] Signed-off-by: Yitian Bu <yitian.bu@tangramtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>

from Designware I2S datasheet, tx/rx XRUN irq is cleared by reading register TOR/ROR, rather than by writing into them. Signed-off-by: Yitian Bu <yitian.bu@tangramtek.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org

of_match_ptr is already conditionally compiled based on CONFIG_OF so further conditional compilation is not required. Remove conditional compilation surrounding of_match_ptr. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
