firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPs

2021-09-27T12:00:42+00:00

wm_adsp originally provided firmware loading on some audio DSP and was implemented as an ASoC codec driver. However, the firmware loading now covers a wider range of DSP cores and peripherals containing them, beyond just audio. So it needs to be available to non-audio drivers. All the core firmware loading support has been moved into a new driver cs_dsp, leaving only the ASoC-specific parts in wm_adsp.

ASoC: wm_adsp: Remove use of snd_ctl_elem_type_t

2021-09-27T12:00:28+00:00

In preparation for moving the generic DSP support out of ASoC, remove the use of the ALSA specific types for the control type. The use of an ALSA type was unnecessary, the simplified code is easier to read and avoids Sparse warnings.

ASoC: wm_adsp: Use snd_ctl_elem_type_t for control types

2020-12-31T13:26:24+00:00

Sparse will complain about trying to convert between values declared as snd_ctl_elem_type_t and other types. This patch converts to consistently use snd_ctl_elem_type_t for control type values. A __force cast is needed in a couple of cases where the control type value is parsed out of a DSP data block.

ASoC: wm_adsp: Support new metadata block ID's

ASoC: wm_adsp: Add support for new Halo core DSPs

2019-03-19T13:00:11+00:00

The Halo core is a new generation of audio DSP architecture from Cirrus Logic. A new iteration of the WMFW file format (v3) is also added, for this new architecture. Currently this format is not supported on the old ADSP2 architecture however support may be added for it in the future.

ASoC: wm_adsp: Parse HOST_BUFFER controls

2018-07-19T14:11:56+00:00

Currently the compressed streams in DSP firmwares are identified essentially by looking at a fixed location inside the firmware. This is fragile and also limits things to a single compressed stream. Here a new form of firmware parameter is added, the HOST_BUFFER which identifies a compressed stream from meta-data in the firmware file. This is more robust and allows for the possiblity of using multiple streams per core in the future. Currently the implementation is still limited to a single stream and will use the first HOST_BUFFER parameter encountered. If there aren't any HOST_BUFFER parameters it will fall back to the legacy way of finding the host buffer. Signed-off-by: Richard Fitzgerald Signed-off-by: Charles Keepax Signed-off-by: Mark Brown

ASoC: wm_adsp: Support acknowledged controls

2016-11-11T15:57:56+00:00

This patch handles publishing acknowledged controls through ALSA. These controls allow user-side to send events to the firmware and wait for the firmware to acknowledge it. Note that although acked controls only operate in the direction host->firmware, and therefore they are write-only as seen from user- side code, we have to make them readable to account for all the code out there that assumes that ALSA controls are always readable (amixer for example.)
