[PATCH v2 0/3] arm64: dts: qcom: Add Eliza CQS EVK support

[PATCH v2 0/3] arm64: dts: qcom: Add Eliza CQS EVK support

[Abel Vesa]

The Eliza EVK platform is built from a reusable base board and an
Eliza System-on-Module. The base board provides connectors for external
peripherals, while each SoM variant provides the SoC, PMICs, LPDDR, and
eMMC.

Add support for the CQ7790S-based Eliza CQS EVK. The series introduces a
CQS SoM DTSI with the board clocks, PMIC regulator supplies, ADSP
firmware and eMMC wiring, then adds a common Eliza EVK DTSI and the final
Eliza CQS EVK DTS that combines both pieces. It also documents both the
CQS SoM and EVK compatibles.

Do this in order to be able to boot to shell with rootfs on eMMC, on the
Eliza CQS EVK board.

Changes in v2:
- Rebased on next-20260519.
- Added missing qcom,eliza-cqs-som to the EVK dts.
- Added in the bindings patch, as that should've been part of this series
  from the start. Also dropped the CQM as support for it is not being
  added. Also reworked as Krzysztof's suggested. It was initially sent
  separately here:
  https://patch.msgid.link/20260515-eliza-bindings-evk-v1-1-8deb81ed86dd@oss.qualcomm.com
- Link to v1: https://patch.msgid.link/20260515-eliza-dts-qcs-evk-v1-0-7169d78a33e1@oss.qualcomm.com

[PATCH v2 1/3] dt-bindings: arm: qcom: Document Eliza CQS SoM and its EVK board

[Abel Vesa]

Document the compatible strings for the Qualcomm Eliza CQS
System-on-Module (SoM) and its EVK board.

The SoM is populated with a CQ7790S Eliza variant, PMICs, LPDDR and
eMMC. The SoM is then connected to the EVK base board, which provides
a multitude of connectors for peripherals.

[PATCH v2 2/3] arm64: dts: qcom: Add Eliza CQS SoM platform

[Abel Vesa]

The Eliza CQS (CQ7790S) System-on-Module is designed to be connected to
an Eliza EVK base board. The SoM provides the SoC, PMICs, LPDDR and eMMC,
while the EVK base board provides connectors for a multitude of
peripherals.

Add the Eliza CQS SoM DTSI so it can be included by the EVK board DTS.
Describe the regulators and board clocks, enable eMMC support through
SDHC1, specify the ADSP firmware and enable the ADSP remoteproc.

[PATCH v2 3/3] arm64: dts: qcom: Add Eliza CQS EVK board

[Abel Vesa]

The Eliza CQS EVK board combines the CQ7790S-based (Eliza) SoM with the
common Eliza EVK base board, which provides connectors for different
peripherals.

Add a common Eliza EVK dtsi for the base board bits that can be reused
alongside other Eliza SoM variants. Then, add the final Eliza CQS EVK dts,
including the CQS SoM and common EVK dtsi.

Re: [PATCH v2 2/3] arm64: dts: qcom: Add Eliza CQS SoM platform

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] Undefined labels referenced in the device tree (`&sdhc_1`, `&remoteproc_adsp`, `&sdc1_default`, and `&sdc1_sleep`) will cause a Device Tree Compiler (DTC) build failure.

arm64: dts: qcom: Add Eliza CQS SoM platform

This commit adds the Eliza CQS SoM DTSI so it can be included by the EVK
board DTS. It describes the regulators and board clocks, enables eMMC
support through SDHC1, specifies the ADSP firmware, and enables the ADSP
remoteproc.

[Severity: Low]
Are the labels &remoteproc_adsp, &sdhc_1, &sdc1_default, and &sdc1_sleep
defined in the base eliza.dtsi?

It appears that these labels are not defined anywhere in the SoC tree,
nor are they provided by any included .dtsi files. This will cause a
Device Tree Compiler (DTC) build failure due to undefined labels.
