Date: Mon Oct 12 2026 - 02:18:29 EST


This series continues work originally posted by Avaneesh Kumar Dwivedi [1].
V2 incorporates review feedback, validation results, and subsequent
updates.

This series adds initial device tree support for the Talos Lyra EVK,
a QCS615-based System on Module (SoM) paired with a common carrier board.

The Talos Lyra SoM is a compact compute module integrating the QCS615 SoC,
PMICs, memory, and essential connectivity. It is designed to be paired with
multiple carrier boards to support different use cases.

Talos Lyra is a distinct SoM revision of the existing Talos EVK SoM. The
key differences are:
- Adds Apache (Lite-on-Module) WLAN on SoC Card.
- Removes SPI-attached CAN transceiver module.
- SDC2 on the existing Talos SoM supported SDIO-based WLAN; it is now
used for the SD card connector only.

Changes in v1:
- dt-bindings for the Talos Lyra EVK board.
- Talos Lyra SoM DTSI with PMIC, regulators, storage (UFS/SD),
QUPv3 instances, ADSP/CDSP remoteprocs, and GPU definitions.
- Talos Lyra EVK board DTS enabling DisplayPort, GPIO expanders,
SPI-attached TPM (ST33), and USB on the carrier board.

Changes in v2:
- Drop qcom,talos-lyra-evk-som compatible from the binding; group
qcom,talos-lyra-evk under the existing talos-evk block instead
- Remove unused regulators vreg_s3a (smps3), vreg_s5a (smps5) and
vreg_s6a (smps6) from the SoM device tree
- Update board compatible string to remove qcom,talos-lyra-evk-som
- Add "talos:" subsystem prefix to patches 2 and 3 subjects
- Set initial-mode to HPM for all LDOs (ldo3, ldo11, ldo13, ldo15, ldo16)
- Add EL2 overlay for talos-lyra-evk as a separate patch (patch 4)

Note: The WLAN node is not included in this series and will be posted
as a follow-up.
