[PATCH 0/2] 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.

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

The board compatible strings are documented by the prerequisite binding
patch:

[PATCH 1/2] 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 2/2] 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 1/2] arm64: dts: qcom: Add Eliza CQS SoM platform

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [High] The `&sdhc_1` node for the eMMC is missing the `bus-width = <8>;` property.
- [Low] The included file `pm7550ba-eliza.dtsi` does not exist in the source tree.

arm64: dts: qcom: Add Eliza CQS SoM platform

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

Are we missing a file in this patch series?

The pm7550ba-eliza.dtsi include does not appear to exist in the repository
or in the submitted patches, which will result in a build failure.

Does this node require an explicit bus-width property for the eMMC?

The node enables mmc-hs400-1_8v, which strictly requires an 8-bit data bus.
Without setting bus-width = <8>, the MMC core will default to a 1-bit bus.

Could this prevent HS400 mode from functioning and degrade storage
performance?

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] The device tree will fail to compile due to an unresolved node reference to `&uart13` in `eliza-evk.dtsi`.
- [Low] The new board compatible string `qcom,eliza-cqs-evk` is not documented in the dt-bindings.

arm64: dts: qcom: Add Eliza CQS EVK board

This commit adds the common Eliza EVK dtsi and the final Eliza CQS EVK dts
files. It provides the device tree configuration for combining the Eliza SoM
with the common EVK base board.

Is this new compatible string documented in the dt-bindings?

A search of the Documentation directory suggests qcom,eliza-cqs-evk is
missing from the binding files, which could cause dt_binding_check to fail.

Will the device tree compiler fail with an unresolved node reference here?

It appears the base SoC file defines the UART as uart14, while this code tries
to reference and modify uart13 which is not defined in the inclusion chain.
