Audio DSP device supports D0 substates in form of D0ix, allowing for preserving more power even when device is still considered active (D0). When entered, certain domains which are not being currently used become power gated. Entering and leaving D0ix is a complex process and differs between firmware generations. Conditions that disallow D0i3 and require immediate D0i0 transition include but may not be limited to: IPC traffic, firmware tracing and SRAM I/O. To make D0ix toggling sane, delay D0i3 transition and refresh the timer each time an IPC is requested.

Firmware provides its own debug functionality. While coredump is one of these, traces are the main area of interest. kfifo is enlisted to cache log data that is being pumped to driver through SRAM. Separate DSP operations are declared as actual feature implementation differs between firmware generations. As log gathering involves usage of IPCs, add all necessary: ENABLE_LOGS and SYSTEM_TIME.

In rare occasions, under stress conditions or hardware malfunction, DSP firmware may fail. Software is notified about such situation with EXCEPTION_CAUGHT notification. IPC timeout is also counted as critical device failure. More often than not, driver can recover from such situations by performing full reset: killing and restarting ADSP.

HDA streaming in DSP world means enlisting HDAudio links as BE interfaces. Another difference when compared to its DMIC and I2S friends is lack of NHLT blob usage - no additional hardware configuration is needed. Similarly to I2S component, HDA populates its DAIs dynamically, here by the means of codec->pcm_list_head. Allows for cutting the number of soc components required to support the interface.

DMIC and I2S interfaces differ in DMA operations from the HDAudio interface. With that in mind, implement all DAI operations to handle non-HDA BE interfaces. To prevent code duplication in newly added code, I2S platform registering is dynamic - makes use of specified port_mask and TDMs array to populate as many DAIs as required.

Not all modules are part of base firmware. Some are part of loadable libraries. These need to be loaded after base firmware reports ready status through FW_READY notification. Their loading process is similar to the base firmware's one. Request the binary file, verify and strip the manifest and load the actual code into DSP memory with help of CLDMA or HD-Audio render stream, depending on audio device generation. List of libraries needed for loading is obtained through the topology - vendor sections specifying the name of firmware files to request.

There is a logic error when removing rt5645 device as the function rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and delete the &rt5645->btn_check_timer latter. However, since the timer handler rt5645_btn_check_callback() will re-queue the jack_detect_work, this cleanup order is buggy. That is, once the del_timer_sync in rt5645_i2c_remove is concurrently run with the rt5645_btn_check_callback, the canceled jack_detect_work will be rescheduled again, leading to possible use-after-free. This patch fix the issue by placing the del_timer_sync function before the cancel_delayed_work_sync.

Currently the checking for if a component sits on the CPU or CODEC side of the DAI link is done with a helper function that checks if the component defines legacy_dai_naming. However, there are already a couple of CPU side components that explicitly opt in to non-legacy DAI naming and it doesn't seem like a very robust solution. Rather than looking for the flag check if the component is attached to any of the CODEC DAIs on the DAI link. This is more robust and helps to bring the core further in the direction of a component being a generic block rather than being classified as platform or CODEC drivers.

Passing the result of the helper function snd_soc_component_is_codec to snd_soc_register_dai is less clear than just passing the DAI naming flag directly. snd_soc_register_dai wants to know if it should use the legacy DAI naming. The CODEC distinction is more of a historical thing and not obviously directly related, and there are already a couple of CPU side components that explicitly opt in to non-legacy DAI naming.

With dual fifo enabled, the case that recording mono sound in the background, playback mono sound twice in parallal, at second time playback sound may distort, the possible reason is using dual fifo to playback mono sound is not recommended. This patch is to provide a option to use multi fifo script, which can be dynamically configured as one fifo or two fifo mode.
