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

[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@oss.qualcomm.com

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.

[PATCH v3 1/3] dt-bindings: arm: qcom: Add Talos Lyra EVK board

[Ruchira Revdekar]

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

Add the qcom,talos-lyra-evk compatible string for the Talos Lyra EVK
board. The Talos Lyra EVK pairs the Talos Lyra SoM with a carrier board.
The SoM uses the same QCS615/SM6150 SoC as the existing Talos EVK, so
qcom,talos-lyra-evk is grouped under the existing talos-evk block rather
than introducing a SoM-specific compatible.

I do not understand this logic at all. Usage of same SoC has nothing to
do with having or not having SoM compatible. Every SoM uses same
compatible as some other device, so we should drop all SoM-compatibles
in the future?.

So if you have a SoM then it can be used with different boards, thus it
should have its own compatible.

Again, explain properly the hardware if this is the chosen design.

Krzysztof

[Severity: Medium]
Should sdhc_2 use vreg_l2a instead of vreg_s4a for vqmmc-supply?

Here, vreg_s4a is constrained to 1.8V-1.829V, while sdhc_2 is the removable SD
card controller. When sdhci_msm_set_regulator_caps() in
drivers/mmc/host/sdhci-msm.c and sdhci_setup_host() in
drivers/mmc/host/sdhci.c check vqmmc, they see that 2.7V-3.6V is unsupported:

drivers/mmc/host/sdhci-msm.c:sdhci_msm_set_regulator_caps()
	if (!IS_ERR(mmc->supply.vqmmc)) {
		if (regulator_is_supported_voltage(supply, 1700000, 1950000))
			caps |= CORE_1_8V_SUPPORT;
		if (regulator_is_supported_voltage(supply, 2700000, 3600000))
			caps |= CORE_3_0V_SUPPORT;

drivers/mmc/host/sdhci.c:sdhci_setup_host()
		if (!regulator_is_supported_voltage(mmc->supply.vqmmc, 2700000,
						    3600000))
			host->flags &= ~SDHCI_SIGNALING_330;

Because CORE_3_0V_SUPPORT is not set and SDHCI_SIGNALING_330 is cleared,
initial 3.3V SD signaling in mmc_power_up() ->
mmc_set_initial_signal_voltage() -> sdhci_msm_start_signal_voltage_switch()
fails with -EINVAL, breaking 3.3V initial I/O signaling and UHS-I voltage
switching.

Meanwhile, vreg_l2a (ldo2, 1.65V-3.1V) is defined in this file with no
consumers, similar to the issue on QCS615 Ride fixed in commit 4614628bea86
("arm64: dts: qcom: qcs615-ride: fix sdhc_2 vqmmc-supply for UHS-I mode").

[PATCH v3 3/3] 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

Also adds a talos-lyra-evk-el2 composite DTB combining
talos-lyra-evk.dtb with the talos-el2 overlay for hypervisor-enabled
