[PATCH v2 0/4] Add support for Talos Lyra EVK board

[PATCH v2 0/4] Add support for Talos Lyra EVK board

[Ruchira Revdekar]

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.

No, this did not happen.

Apologies. The tag was added based on internal validation but Nirmesh
had not yet formally posted it to the mailing list at the time of
submission. That was a mistake on our part.

Nirmesh has since replied to this thread with his formal Tested-by:

Tested-by: Nirmesh Kumar Singh <nirmesh.singh@oss.qualcomm.com>

will include it correctly in v3. The same applies to the identical
tag in patch 2.

Again, this did not happen, otherwise explain me how did you execute
this code on the device during your "formal validation".

[Severity: Medium]
Will this configuration prevent standard removable SD cards from initializing?

Standard removable SD cards require 3.3V for initialization, but the
vqmmc-supply for sdhc_2 is bound to the fixed 1.8V vreg_s4a.

This mismatch typically causes regulator_set_voltage() to fail during MMC
core initialization, breaking SD card support. Should this use the unused
vreg_l2a instead, since it is configured with a 1.65V to 3.10V range?

[PATCH v2 3/4] arm64: dts: qcom: talos: Add Talos Lyra EVK board

[Ruchira Revdekar]

From: Avaneesh Kumar Dwivedi <avaneesh.dwivedi@oss.qualcomm.com>

Add the device tree for the Talos Lyra EVK platform which combines
the Talos Lyra EVK SoM and Lyra carrier board.

This device tree adds board-specific peripheral configuration on top
of the SoM, including:

- Native DisplayPort output
- GPIO expanders on i2c5
- SPI-attached TPM (ST33)
- USB host and peripheral controllers
- Power and reset keys

Is it 'lyra' or 'Lyra'?

Why is it being declared here rather than in the DP controller?
Declaring it here would bypass DP controller state machine.

Is it going to only support peripheral mode or is OTG going to be added
later?

Same question. Is it host-only or will OTG be added later?

Is there a separate VBUS supply if it's the host mode controller?

Also, forgot to ask in the first review. Are all the USB supplies routed

[PATCH v2 4/4] arm64: dts: qcom: talos: Add EL2 overlay for talos-lyra-evk

[Ruchira Revdekar]

Add support for building an EL2 combined DTB for the talos-lyra-evk
in the Qualcomm DTS Makefile.

The new talos-lyra-evk-el2.dtb is generated by combining the base
talos-lyra-evk.dtb with the talos-el2.dtbo overlay, enabling EL2-specific
configurations required by the platform.

Thanks for the review.

I'll squash the EL2 Makefile changes into the patch introducing the Talos
Lyra EVK DTS in the next revision.
