ASoC: SOF: sof-audio: add sof_dai_get_tdm_slots function

2024-05-29T10:10:54+00:00

An new interface, sof_dai_get_tdm_slots(), is added for machine driver
to get tdm slot number from topology. The dai_get_param() callback
needs to support new parameter type SOF_DAI_PARAM_INTEL_SSP_TDM_SLOTS
by returning the tdm slot number of specific SSP port.

Merge tag 'asoc-v6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-05-13T09:39:49+00:00

ASoC: Updates for v6.10

This is a very big update, in large part due to extensive work the Intel
people have been doing in their drivers though it's also been busy
elsewhere.  There's also a big overhaul of the DAPM documentation from
Luca Ceresoli arising from the work he did putting together his recent
ELC talk, and he also contributed a new tool for visualising the DAPM
state.

 - A new tool dapm-graph for visualising the DAPM state.
 - Substantial fixes and clarifications for the DAPM documentation.
 - Very large updates throughout the Intel audio drivers.
 - Cleanups of accessors for driver data, module labelling, and for
   constification.
 - Modernsation and cleanup work in the Mediatek drivers.
 - Several fixes and features for the DaVinci I2S driver.
 - New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
   Rockchip RK3308 and Texas Instruments PCM6240.

ALSA/ASoC: include: clarify Copyright information

For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

ASoC: SOF: Constify stored pointer to snd_sof_dsp_ops

2024-04-29T15:16:49+00:00

The core code does not modify the 'struct snd_sof_dsp_ops', stored in
'struct sof_dev_desc'.  Make the pointer to 'struct snd_sof_dsp_ops'
const to annotate this, make code a bit safer and allow individual
drivers to also define this structure as const.

ASoC: SOF: Add placeholder for platform IPC type and path overrides

2023-11-29T13:25:06+00:00

Add a struct sof_loadable_file_profile which can be filled by platforms
(sof-acpi-dev.c, sof-of-dev.c and sof-acpi-dev.c) to be able to use common,
generic code to handle path customization.

ASoC: SOF: Introduce generic names for IPC types

2023-09-19T12:49:05+00:00

Change the enum names for the IPC types to be more descriptive and drop
tying the IPC4 to Intel SoCs.

Add defines to avoid build breakage while the related code is
modified to use the new enum names.

ASoC: SOF: Pass PCI SSID to machine driver

2023-09-12T17:53:48+00:00

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.

ASoC: SOF: Add flag and state which will be used for DSP-less mode

2023-04-04T11:42:33+00:00

The DSPless mode of the ASoC/SOF driver can be used for hardware
verification and debug on platforms with HDaudio codecs. The DSP mode is
still needed on existing platforms for SSP, DMIC, SoundWire interfaces
managed by the GP-DMA.

This mode is also helpful to compare the legacy HDaudio driver with the
ASoC/SOF driver wrt. codec management and handling. In theory we use the
same code but differences are sometimes seen on jack detection and event
handling.

ASoC: SOF: Add path definition for external firmware libraries

2022-10-21T12:05:03+00:00

IPC4 based firmware supports dynamically loaded external libraries.
The libraries will be not stored alongside of the firmware or tplg files.

For intel platforms the default path will be:
intel/avs-lib|sof-ipc4-lib// if a community key is used on the
given machine then the libraries will be under 'community' directory, like
it is done for the firmware itself.
