[PATCH v1] arm64: dts: qcom: Add dmic45 support to rb3gen2 vision mezzanine overlay

[Kumar Anurag]

Add pinctrl states and VA macro routing for two additional digital
microphones (DMIC4/DMIC5) that are present on the vision mezzanine
add-on board, mirroring the dmic01/dmic23 pattern already used for
the on-board microphones.

This should go to kodiak.dtsi

[PATCH v2] arm64: dts: qcom: Add dmic45 support to rb3gen2 vision mezzanine overlay

[Kumar Anurag]

Add pinctrl states and VA macro routing for two additional digital
microphones (DMIC4/DMIC5) that are present on the vision mezzanine
add-on board, mirroring the dmic01/dmic23 pattern already used for
the on-board microphones.

Changes in v2:
- Move the dmic45 pinctrl states into kodiak.dtsi instead of the
  mezzanine overlay, since gpio12/gpio13 belong to the SoC's
  lpass_tlmm block, mirroring the existing dmic01/dmic23 definitions
  (Konrad).
- Link to v1: https://lore.kernel.org/r/20261027115115.1822423-1-kumar.singh@oss.qualcomm.com
