[PATCH v2 2/6] ASoC: dt-bindings: qcom,sm8250: Add RubikPi 3 sound card

From: Hongyang Zhao

Date: Wed Jul 15 2026 - 12:29:09 EST


The QCS6490-based Thundercomm RubikPi 3 routes primary MI2S to an
external ES8316 headset codec and quaternary MI2S to the LT9611 HDMI
bridge. This requires board-specific DAI clocking and jack setup in the
sc8280xp machine driver.

The existing QCM6490 and QCS6490 compatibles select machine data for
boards using different codec and audio routing arrangements, so they
cannot be used as compatible fallbacks for RubikPi 3.

Add a dedicated compatible to select the RubikPi 3 machine data.
