[PATCH v4] arm64: dts: qcom: qcs6490-rubikpi3: Add audio support
From: Hongyang Zhao
Date: Mon Sep 28 2026 - 08:19:08 EST
RubikPi 3 uses the AudioReach firmware path for its external audio
interfaces. Primary MI2S connects to an ES8316 codec for headset playback
and capture, while quaternary MI2S feeds the LT9611 HDMI bridge.
Describe the ES8316 supplies, MCLK, jack detection and audio routing, and
add the primary and quaternary MI2S links. The 1.8 V and 3.3 V codec
supplies are both controlled by GPIO117.

This revision contains only the Rubik Pi 3 device-tree patch. The five
ASoC patches from v3 have been applied to sound.git and are already in
next-20260925. The AudioReach topology and ALSA UCM updates will be
submitted separately.
Changes in v4:
- Set I2C0 clock-frequency to 100 kHz explicitly, preserving the rate
used by the GENI I2C driver's default.
- Rebase the device-tree patch onto next-20260925 and omit the five
ASoC patches already applied to sound.git.
