Enter to close more power control widgets at suspend. Remove hp_pin check. Add the default pin 0x21 as headphone. Supported low power consumption, it must do depop procedure when headset jack was plugged or unplugged. So, alc225_init() and alc225_shutup() must run delay when headset jack was plugged or unplugged. If depop procedure not run with delay, it will have a chance to let power consumption raise high.

On the machines with AMD GPU or Nvidia GPU, we often meet this issue: after s3, there are 4 HDMI/DP audio devices in the gnome-sound-setting even there is no any monitors plugged. When this problem happens, we check the /proc/asound/cardX/eld#N.M, we will find the monitor_present=1, eld_valid=0. The root cause is BIOS or GPU driver makes the PRESENCE valid even no monitor plugged, and of course the driver will not get the valid eld_data subsequently. In this situation, we should not report the jack_plugged event, to do so, let us change the function hdmi_present_sense_via_verbs(). In this function, it reads the pin_sense via snd_hda_pin_sense(), after calling this function, the jack_dirty is 0, and before exiting via_verbs(), we change the shadow pin_sense according to both monitor_present and eld_valid, then in the snd_hda_jack_report_sync(), since the jack_dirty is still 0, it will report jack event according to this modified shadow pin_sense. After this change, the driver will not report Jack_is_plugged event through hdmi_present_sense_via_verbs() if monitor_present is 1 and eld_valid is 0. Signed-off-by:

The driver will check the monitor presence when resuming from suspend, starting poll or interrupt triggers. In these 3 situations, the jack_dirty will be set to 1 first, then the hda_jack.c reads the pin_sense from register, after reading the register, the jack_dirty will be set to 0. But hdmi_repoll_work() is enabled in these 3 situations, It will read the pin_sense a couple of times subsequently, since the jack_dirty is 0 now, It does not read the register anymore, instead it uses the shadow pin_sense which is read at the first time. It is meaningless to check the shadow pin_sense a couple of times, we need to read the register to check the real plugging state, so we set the jack_dirty to 1 in the hdmi_repoll_work().

Merge tag 'asoc-v5.2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.2 This is a pretty huge set of changes, it's been a pretty active release all round but the big thing with this release is the Sound Open Firmware changes from Intel, providing another DSP framework for use with the DSPs in their SoCs. This one works with the firmware of the same name which is free software (unlike the previous DSP firmwares and framework) and there has been some interest in adoption by other systems already so hopefully we will see adoption by other vendors in the future. Other highlights include: - Support for MCLK/sample rate ratio setting in the generic cards. - Support for pin switches in the generic cards. - A big set of improvements to the TLV320AIC32x4 drivers from Annaliese McDermond. - New drivers for Freescale audio mixers, several Intel machines, several Mediatek machines, Meson G12A, Sound Open Firmware and Spreadtrum compressed audio and DMA devices.

For Spreadtrum audio platform driver, it need allocate a larger DMA buffer dynamically to copy audio data between userspace and kernel space, but that will increase the risk of memory allocation failure especially the system is under heavy load situation. To make sure the audio can work in this scenario, we usually reserve one region of memory to be used as a shared pool of DMA buffers for the platform component. So add of_reserved_mem_device_init_by_idx() function to initialize the shared pool of DMA buffers to be used by the platform component. Signed-off-by:

This recent commit: 5768402f ("perf/ring_buffer: Use high order allocations for AUX buffers optimistically") overlooked the fact that the previous one page granularity of the AUX buffer provided an implicit double buffering capability to the PMU driver, which went away when the entire buffer became one high-order page. Always make the full-trace mode AUX allocation at least two-part to preserve the previous behavior and allow the implicit double buffering to continue. Reported-by:

On kbl_rt5663_max98927, commit 38a5882e ("ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE") This key pair mapping to play/pause when playing Youtube The Android 3.5mm Headset jack specification mentions that BTN_0 should be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE, which has much broader userspace support. For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle play/pause of videos and audio, but does not handle KEY_MEDIA. Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the new USB headset spec requires KEY_PLAYPAUSE for BTN_0. https://source.android.com/devices/accessories/headset/usb-headset-spec The same fix is required on Chrome kbl_da7219_max98357a.

The prepare() ioctl for BE dai link gets called both when the stream is started and when it is resumed from suspend. SOF uses this ioctl to set the hw params again only if the stream has been suspended. When the stream is started, the hw_params ioctl gets called before prepare() and hw_params is set for the BE dai link. So the prepare call does not need to do anything further. When the stream resumes after system suspend, SOF requires that the hw_params be set again for the BE dai. In order to determine which streams should set the hw params during prepare(), an internal flag called "hw_params_upon_resume" is introduced in struct sof_intel_hda_stream. The flag is set for hda streams when the sof device suspends and is cleared after hw_params is set. Signed-off-by:

When using a shared IRQ between IPC interrupt and stream IOC interrupt, the interrupt handlers need to check the interrupt source before scheduling their respective IRQ threads. In the case of IPC handler, it should check if it is an IPC interrupt before waking up the IPC IRQ thread. The IPC IRQ thread, once scheduled, does not need to check the IRQ source again. So, remove the superfluous check in the thread. Remove the irq_status field from snd_sof_dev struct also as it is no longer needed. Signed-off-by:

The IPC implementation in SOF requires sending IPCs serially: we should not send a new IPC command to the firmware before we get an ACK (or time out) from firmware, and the IRQ processing is complete. snd_pcm_period_elapsed() can be called in interrupt context before IRQ_HANDLED is returned. When the PCM is done draining, a STOP IPC will then be sent, which breaks the expectation that IPCs are handled serially and leads to IPC timeouts. This patch adds a workqueue to defer the call to snd_pcm_elapsed() after the IRQ is handled. Signed-off-by:
