From: Karthik S

Date: Mon Oct 26 2026 - 09:26:16 EST


This series adds audio support for the QCS6490 RB3Gen2 (kodiak) board.

The board features an LT9611UXC HDMI bridge connected over secondary
MI2S and a USB-C DisplayPort output. This series enables audio output
over both paths:

Changes included in this series:
- Patch 1/3: Enable secondary MI2S pinctrl and add the MI2S dai-link
for HDMI audio output via the LT9611UXC bridge, and sort wsa-dai-link
to maintain alphabetical order
- Patch 2/3: Add #sound-dai-cells to the LT9611UXC node to allow it
to be referenced as a sound DAI provider
- Patch 3/3: Add a DisplayPort dai-link to enable audio over USB-C DP

---
Changes since v1:
- Separate patch for #sound-dai-cells addition to lt9611.
- mi2s1-playback-dai-link kept sorted before va-dai-link.
- Subject line updated to mention kodiak.
- Patch 3 enables audio for USB-C DP only.
- Dropped patches: ASoC: qcom: q6dsp: Update bit format support for
secondary i2s and ASoC: qcom: sc8280xp: don't force S16_LE in
hw_params fixup.
