[PATCH 00/17] arm64: dts: Add MQS1 sound card support for i.MX9 EVK platforms

From: Chancel Liu <[email protected]>

MQS (Medium Quality Sound) is an internal audio DAC available on multiple
NXP i.MX9 SoCs. On EVK boards, the MQS output pins are typically shared
with other peripherals (CAN, PDM microphone, etc.), so enabling MQS
requires switching board-level pin muxes and disabling the conflicting
device.

This series adds MQS1 sound card support across the following platforms:
  - i.MX91 11x11 EVK
  - i.MX93 11x11 EVK
  - i.MX93 14x14 EVK
  - i.MX943 EVK
  - i.MX95 15x15 EVK
  - i.MX952 EVK
