2023-12-08ASoC: wm2200: Convert to GPIO descriptorsLinus Walleij1-2/+0
This converts the WM2200 codec to use GPIO descriptors. This is a pretty straight-forward conversion, and it also switches over the single in-tree user in the S3C Cragganmore module for S3C 6410. This coded does not seem to get selected or be selectable through Kconfig, I had to hack another soundcard Kconfig entry to select it for compile tests.

2023-12-08ASoC: wm1250-ev1: Convert to GPIO descriptorsLinus Walleij1-24/+0
This converts the WM1250-EV1 codec to use GPIO descriptors. It turns out that the platform data was only used to pass some global GPIO numbers from a board file, so we get rid of this and also switch over the single in-tree user in the S3C Cragganmore module for S3C 6410. The driver obtains two GPIO lines named OSR and master and just pull them low, we leave this behaviour as it was.

Introduce a set of functions that ultimately facilite SDxFMT-related calculations in atomic manner: First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits() helpers that separate the base functionality from the HDAudio-specific one. snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

Subformat options are ignored when setting up hardware parameters and assigning PCM stream capabilities. Account for them to allow for granular format selection. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone.

2023-11-27ALSA: pcm: Introduce MSBITS subformat interfaceJaroslav Kysela1-0/+7
Improve granularity of format selection for S32/U32 formats by adding constants representing 20, 24 and MAX most significant bits. The MAX means the maximum number of significant bits which can the physical format hold. For 32-bit formats, MAX is related to 32 bits. For 8-bit formats, MAX is related to 8 bits etc. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone. The approach of subformat being part of struct snd_pcm_hardware is a compromise between ALSA and ASoC allowing for hw_params-intersection code to be alloc/free-less while not adding any new responsibilities to ASoC runtime structures.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. simple_util_remove() returned zero unconditionally. Make it return void instead and convert all users to struct platform_device::remove_new().

2023-09-15ASoC: SOF: ipc4: Add new message type: SOF_IPC4_GLB_LOAD_LIBRARY_PREPAREPeter Ujfalusi1-4/+11
On Intel platforms there is a strict order requirement for the DMA programming: DSP side configures the buffer and sets the GEN bit Host side sets the RUN bit. In order to follow this flow, a new global message type has been added to prepare the DSP side of the DMA: host sends LOAD_LIBRARY_PREPARE with the dma_id DSP side sets its buffer and sets the GEN bit Host sets the RUN bit Host sends LOAD_LIBRARY with dma_id and lib_id DSP receives the library data. It is up to the platform code to use the new prepare stage message and how to handle the reply to it from the firmware, which can indicate that the message type is not supported/handled. In this case the kernel should proceed to the LOAD_LIBRARY stage assuming a single stage library loading: host sends LOAD_LIBRARY_PREPARE with the dma_id DSP replies that the message type is not supported/handled Host acknowledges the return code and sets the RUN bit Host sends LOAD_LIBRARY with dma_id and lib_id DSP receives the library data.

2023-09-12ASoC: SOF: Pass PCI SSID to machine driverRichard Fitzgerald2-0/+15
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.
