[PATCH 13/13] ASoC: qcom: Add Shikra QAIF support
From: Harendra Gautam
Date: Fri Jun 05 2026 - 06:43:52 EST
Add the Shikra variant data for the Qualcomm Audio Interface driver and
hook it up to Kconfig and the qcom ASoC Makefile.
Shikra uses QAIF to move PCM data between memory, MI2S interfaces and the
Bolero codec CDC DMA paths. Without the SoC-specific register layout, DMA-
to-DAI mappings, clock list and DAI descriptors, Shikra-based platforms
cannot enable playback or capture through this block.
Provide the Shikra QAIF register field definitions, DMA mappings, DAI
descriptors, clock configuration and platform match data, and build them as
part of the snd-soc-qcom-qaif module.
