[PATCH v2 5/9] ASoC: qcom: q6asm-dai: add support to wma decoder
by Vinod Koul 13 Mar '20

13 Mar '20

Qualcomm DSPs also supports the wma decoder, so add support for wma decoder and convert the snd_codec_params to qdsp format.

This series adds more WMA profiles and WMA decoder parameters to UAPI and then support for these in qcom driver. It also adds FLAC and APE IDs and decoder parameters to UAPI and then support in qcom driver This was tested on Dragon board RB3. Last, bump up the compressed version so that userspace can check for the support. Since the series touches compress uapi and asoc, it would make sense to go thru asoc tree with acks.

[alsa-devel] [RESEND 0/4] Add a better separation between i.MX8 families
by Daniel Baluta 12 Mar '20

12 Mar '20

From: Daniel Baluta <daniel.baluta(a)nxp.com> So far the implementation was designed to support a generic platform named i.MX8. Anyhow, now working with specific i.MX8 instances we need to account for the differences. i.MX8 naming can be confusing at the first glance, so we need to have a clean separation between different platforms. Here is the split of i.MX8 per platforms. Notice that i.MX8 names the entire family, but also a sub-family. imx8 ├── imx8 │ └── imx8qm (*) ├── imx8m │ ├── imx8mm │ ├── imx8mn │ ├── imx8mp (*) │ └── imx8mq └── imx8x └── imx8qxp (*) Platforms marked with (*) contain a DSP. In the future there might be more platforms. This patchseries does the following: * renames imx8 to imx8x (because the only supported platform now is imx8qxp). * adds support for imx8 (which is imx8qm) Paul Olaru (4): ASoC: SOF: Rename i.MX8 platform to i.MX8X ASoC: SOF: imx8: Add ops for i.MX8QM ASoC: SOF: Add i.MX8QM device descriptor dt-bindings: dsp: fsl: Add fsl,imx8qm-dsp entry .../devicetree/bindings/dsp/fsl,dsp.yaml | 1 + sound/soc/sof/imx/imx8.c | 57 ++++++++++++++++++- sound/soc/sof/sof-of-dev.c | 10 ++++ 3 files changed, 65 insertions(+), 3 deletions(-) -- 2.17.1

NHLT (Non-HDAudio Link Table) provides configuration of audio endpoints for Intel SST (Smart Sound Technology) DSP products. Similarly to other ACPI tables, data provided by BIOS may not describe it correctly, thus overriding is required. ACPI override mechanism checks for unknown signature before proceeding. Update known signatures array to support NHLT. CC: Erik Kaneda <erik.kaneda(a)intel.com> CC: Robert Moore <robert.moore(a)intel.com> CC: Rafael J.
