ASoC: SOF: Add Sound Open Firmware driver core The Sound Open Firmware driver core is a generic architecture independent layer that allows SOF to be used on many different architectures and platforms. It abstracts DSP operations and IO methods so that the target DSP can be an internal memory mapped or external SPI or I2C based device. This abstraction also allows SOF to be run on many different VMs on the same physical HW. SOF also requires some data in ASoC PCM runtime data for looking up SOF data during ASoC PCM operations.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops' Now that we start having multiple platforms with minor variants, the use of the const qualifier for 'dsp_ops' is starting to be sub-optimal: the structures are copied across platforms, with only a couple of members that differ. This patch removes the const qualifier without any functionality changes, and adds an optional initialization callback. In follow-up patches, the dsp_ops will revisited for Intel HDaudio platforms, with the differences added programmatically over a common baseline.

ASoC: SOF: Pass PCI SSID to machine driver Pass the PCI SSID of the audio interface through to the machine driver. This allows the machine driver to use the SSID to uniquely identify the specific hardware configuration and apply any platform-specific configuration. struct snd_sof_pdata is passed around inside the SOF code, but it then passes configuration information to the machine driver through struct snd_soc_acpi_mach and struct snd_soc_acpi_mach_params. So SSID information has been added to both snd_sof_pdata and snd_soc_acpi_mach_params. PCI does not define 0x0000 as an invalid value so we can't use zero to indicate that the struct member was not written. Instead a flag is included to indicate that a value has been written to the subsystem_vendor and subsystem_device members. sof_pci_probe() creates the struct snd_sof_pdata. It is passed a struct pci_dev so it can fill in the SSID value. sof_machine_check() finds the appropriate struct snd_soc_acpi_mach. It copies the SSID information across to the struct snd_soc_acpi_mach_params. This done before calling any custom set_mach_params() so that it could be used by the set_mach_params() callback to apply variant params. The machine driver receives the struct snd_soc_acpi_mach as its platform_data.

In sof_machine_check if there is no ACPI machine exist, the function will return -ENODEV directly, that's we don't expected if we do not base on ACPI machine. 2. In snd_sof_new_platform_drv the component driver need a driver name to do ignore_machine, currently the driver name is obtained from machine->drv_name, and the type of machine is snd_soc_acpi_mach.

ASoC: SOF: Add support for on-demand DSP boot On system suspend / resume we always power up the DSP and boot the firmware, which is not strictly needed as right after the firmware booted up we power the DSP down again on suspend and we also power it down after resume after some inactivity. Out of caution, add a new platform descriptor flag to enable on-demand DSP boot since this might not work without changes to platform code on certain platforms. With the on-demand dsp boot enabled we will not boot the DSP and firmware up on system or rpm resume, just enable audio subsystem since audio IPs, like HDA and SoundWire might be needed (codecs suspend/resume operation). Only boot up the DSP during the first hw_params() call when the DSP is really going to be needed. In this way we can handle the audio related use cases: normal audio use (rpm suspend/resume) system suspend/resume without active audio system suspend/resume with active audio system suspend/resume without active audio, and audio start before the rpm suspend timeout Add module option to force the on-demand DSP boot to allow it to be disabled or enabled without kernel change for testing.
