[PATCH v1 0/5] ASoC: qcom: Add Shikra IQS LT9611UXD EVK audio support

From: Karthik S

Date: Thu Oct 22 2026 - 06:10:27 EST


This series adds audio support for the Shikra IQS EVK board variant
that uses the LT9611UXD HDMI bridge as an I2S audio codec instead of
the MAX98091 codec used on the base Shikra IQS EVK.

The Shikra IQS platform uses modem-DSP based audio processing. The
base IQS variant uses a third-party MAX98091 codec. This series adds
support for a board subtype where the LT9611UXD HDMI bridge takes the
place of the MAX98091 on the primary I2S bus, allowing HDMI audio
output without the on-board codec.

Changes included in this series:
- Patch 1/5: Add the shikra-iqs-lt9611uxd-sndcard compatible to the
DT binding
- Patch 2/5: Add the DT overlay for the LT9611UXD EVK variant, with a
label fix to shikra-iqs-evk.dts and Makefile entry
- Patch 3/5: Extend q6apm frontend DAI to support 32-bit sample format
- Patch 4/5: Conditionally skip S16_LE fixup for MI2S and DisplayPort
DAIs so they can negotiate format freely
- Patch 5/5: Add shikra-iqs-lt9611uxd-evk compatible to the sc8280xp
machine driver
