[PATCH v5 0/2] arm64: dts: qcom: QCS615 Talos EVK audio support

[Le Qi]

This series adds initial audio support for the QCS615-based Talos EVK
platform. It introduces the GPR (Generic Pack Router) node in the SoC
device tree and enables a sound card node with the DA7212 codec on the
Talos EVK board.

With these changes, playback through headphones and capture from the
headset microphone have been tested and verified to work.

Changelog:

v5:
  - Moved mclk support to codec since Krystof does not agree to include
    it within the DAI node. Link: https://lore.kernel.org/all/5941830f-5892-4e75-bc27-04095b5ca28f@kernel.org/
  - v4-link: https://lore.kernel.org/all/20260324060405.3098891-1-le.qi@oss.qualcomm.com/

v4:
  - Added mclk support for recording to fix clipping issue.
  - v3-link: https://lore.kernel.org/all/20251204083225.1190017-1-le.qi@oss.qualcomm.com/

v3:
  - Updated sound card model name to "TALOS-EVK".
  - v2-link: https://lore.kernel.org/all/20251125033311.254869-1-le.qi@oss.qualcomm.com/

v2:
  - Address Konrad's comment to modify the commit message and
    group GPIO pins together into a single entry, moved to the
    SoC-level DTSI for reuse.
  - v1-link: https://lore.kernel.org/all/20251024023720.3928547-1-le.qi@oss.qualcomm.com/

[PATCH v5 1/2] arm64: dts: qcom: talos: Add GPR node, audio services, and MI2S1 TLMM pins

[Le Qi]

This patch adds the Generic Pack Router (GPR) node together with
Audio Process Manager (APM) and Proxy Resource Manager (PRM)
audio service nodes to the Talos device tree description.

It also introduces MI2S1 pinctrl states for data0, data1, sck,
and ws lines, grouped into a single entry at the SoC-level DTSI
for better reuse and clarity.

[PATCH v5 2/2] arm64: dts: qcom: talos-evk: Add sound card support with DA7212 codec

[Le Qi]

Add the sound card node for QCS615 Talos EVK with DA7212 codec
connected over the Primary MI2S interface. The configuration enables
headphone playback and headset microphone capture, both of which have
been tested to work.
