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

[Avaneesh Kumar Dwivedi]

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 Supported SDIO based WLAN on existing Talos SoM, while now it is
    used for SD card connector only.

This series includes:
  - 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.

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

[PATCH 2/3] arm64: dts: qcom: Add Talos Lyra EVK SoM platform

[Avaneesh Kumar Dwivedi]

Introduce the device tree for the QCS615-based Talos Lyra EVK SoM.
Lyra EVK SoM a compact compute module integrating the QCS615 SoC,
PMIC, and essential connectivity, designed to mount on carrier boards.

The initial SoM device tree includes basic support for:

- CPU and memory
- PMIC and board-level regulators
- UFS and SD card storage
- QUPv3 (I2C/SPI/UART) instances
- ADSP/CDSP remoteprocs
- GPU

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

[Avaneesh Kumar Dwivedi]

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

EVK means Evalkit usually, so SoM rarely is EVK. Are you sure this is
the correct name?

This s-o-b chain says Monish, Rakesh, Sayali, and Nirmesh first wrote
the patch, but the way you sent it claims you authored it. Retain
Nirmesh as author or fix the chain.

I don't see anything referencing s3a, s5a, and s6a, are you sure that
rpmh doesn't handle the SMPSs for us automatically?

Do we actually want to vote for s4a from Linux?

That's a wide span, narrow it to what the consumers need.

Are you sure you want to go LPM here?

I'm failing to see how that differs from that talos.dtsi already says.

That said, this list is incomplete and needs to be corrected - can be
done separately.

That's what it says in talos.dtsi already. I must be misunderstanding
something?

I don't think there's value in claiming compatibility with the som, just
add qcom,talos-lyra-evk to the node above.
