[PATCH v3 0/3] Add support for Talos Lyra EVK board

[Ruchira Revdekar]

This series continues work originally posted by Avaneesh Kumar Dwivedi [1].

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

Note: The following are not included in this series and will be posted
as follow-ups:
  - WLAN node
  - USB Type-C OTG role switching via CYPD6129 controller (OTG support,
    VBUS supply management). USB controllers are set to peripheral/host
    for initial bring-up only.

Changes in v3:
- Remove inapplicable Tested-by from dt-bindings patch
- Fix DP HPD: use native pinctrl in mdss_dp0 instead of hpd-gpios in dp0-connector
- Fix model string: capitalize "Lyra"
- Squash EL2 overlay Makefile changes into board DTS patch
- Move USB PHY supply nodes to SoM DTSI (supplies are SoM PMIC-routed)
- Sort &node overrides alphabetically in board DTS (&tlmm before &usb_*)
- Reword dt-bindings commit message: clarify board/SoM relationship and explain absence of SoM-specific compatible
- Link to v2: https://patch.msgid.link/20261012-talos-lyra-evk-v2-v2-0-dcc9316ebb59@xxxxxxxxxxxxxxxx

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)

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.
