[PATCH v1 0/3] arm64: dts: qcom: Add Vicharak Axon Mini

[PATCH v1 0/3] arm64: dts: qcom: Add Vicharak Axon Mini

[Ajit Singh]

Add initial support for the Vicharak Axon Mini, a QCS6490-based
single-board computer.

This series adds the Vicharak vendor prefix, documents the board
compatible, and adds the initial board DTS.

Tested:
- debug UART
- eMMC
- UFS
- SDIO WLAN
- USB 2.0 host
- PCIe

Re: [PATCH v1 3/3] arm64: dts: qcom: Add Vicharak Axon Mini

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 5 potential issue(s) to consider:
- [High] The `camera-thermal` zone references a non-existent thermal sensor index.
- [High] The `pm8350c_temp_alarm` node polls the wrong PMIC's die temperature.
- [Medium] The `sdhc_1` eMMC node is missing the `bus-width` property, falling back to 1-bit mode.
- [Low] Peripheral regulators bypass power management by omitting consumers, and the Type-C regulator is completely unpowered.
- [Low] Regulator naming typo for the PCIe1 3.3V supply.

Author: Ajit Singh <blfizzyy@gmail.com>

arm64: dts: qcom: Add Vicharak Axon Mini

Add DTS for the Vicharak Axon Mini board based on the Qualcomm
QCS6490 SoC. This adds debug UART, eMMC, UFS, SDIO WLAN, USB 2.0
host, PCIe, support along with regulators.

The &pmk8350_adc_tm node only defines subnodes for reg = <0>, reg = <1>, and
reg = <3>.

Does this missing sensor index 2 cause the thermal framework to fail to look
up the sensor and bind the camera thermal zone?

Since this regulator lacks both regulator-always-on and a consumer node that
would request it, will this regulator ever be enabled?

Additionally, do regulators like vcc_pcie0_dsi_3v3 and vcc_pcie1_3v3 bypass
runtime power management by relying on regulator-always-on instead of being
linked to their consumers?

This isn't a bug, but the regulator-name omits the index '1' compared to its
node name.

Does reading PMK8350_ADC7_DIE_TEMP cause the pm8350c_temp_alarm to track the
primary PMK8350 PMIC's temperature instead of its own PM8350C PMIC?

Does this node fall back to a 1-bit bus width without an explicitly defined
bus-width property, degrading eMMC performance?

nit: Please put

Let's also keep a \n before the 'status' property, file-wide

It's already disabled in kodiak.dtsi, you can drop this override

It should be working fine, any reason?

Is there anything interesting connected to these buses?

ICE is kept disabled because enabling the ICE node currently causes a
fatal SError during ICE probe on this board:

    qcom_ice_create+0x90/0x274 [qcom_ice]
    qcom_ice_probe+0x38/0x80 [qcom_ice]
    Kernel panic - not syncing: Asynchronous SError Interrupt

UFS works without ICE, so I kept ICE disabled for the initial board
support.

PCIe0 is routed to the onboard NVMe slot. PCIe1 is routed to the
modular HAT connector, where the attached endpoint depends on the HAT
module, for example Ethernet or USB.

[PATCH v2 0/3] arm64: dts: qcom: Add Vicharak Axon Mini

[Ajit Singh]

Add initial support for the Vicharak Axon Mini, a QCS6490-based
single-board computer.

This series adds the Vicharak vendor prefix, documents the board
compatible, and adds the initial board DTS.

Tested:
- debug UART
- eMMC
- UFS
- SDIO WLAN
- USB 2.0 host
- PCIe

Changes in v2:
- Drop unused Type-C VBUS regulator.
- Drop invalid camera thermal zone.
- Drop incorrect PM8350C thermal alarm override.
- Fix PCIe1 3.3 V regulator name.
- Drop redundant EUD disable override.
- Keep ICE disabled due to fatal SError during qcom_ice_create().
- Fix pinctrl property ordering.
- Sort top-level label references.
- Add blank lines before status properties.

Re: [PATCH v2 3/3] arm64: dts: qcom: Add Vicharak Axon Mini

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The PCIe endpoints lack their power supply definitions (`vddpe-3v3-supply`), relying instead on `regulator-always-on`.
- [Medium] The USB 2.0 host controller lacks its VBUS power supply definition (`vbus-supply`), relying instead on `regulator-always-on`.

Author: Ajit Singh <blfizzyy@gmail.com>

arm64: dts: qcom: Add Vicharak Axon Mini

Add DTS for the Vicharak Axon Mini board based on the Qualcomm QCS6490 SoC.
This adds debug UART, eMMC, UFS, SDIO WLAN, USB 2.0 host, PCIe support along
with regulators.

Can the &pcie0 node properly power-manage its endpoint without a
vddpe-3v3-supply property?

The device tree defines vcc_pcie0_dsi_3v3 with regulator-always-on and doesn't
link it here. This breaks proper PCIe power management, as the driver cannot
turn power off during suspend or reset sequences.

Similarly here, should vcc_pcie1_3v3 be referenced as vddpe-3v3-supply for
the &pcie1 node instead of relying on regulator-always-on?

Does the USB 2.0 host controller need a vbus-supply reference here?

The device tree defines vcc_5v0_usb2_0 as a 5V regulator but relies on
regulator-always-on instead of referencing it as vbus-supply (typically
via a usb-a-connector child node). Without this linkage, the USB driver
cannot control VBUS power when the port is inactive or suspended.

Do not attach (thread) your patchsets to some other threads (unrelated
or older versions). This buries them deep in the mailbox and might
interfere with applying entire sets. See also:

This is an automated instruction, just in case, because many review
tags are being ignored. If you know the process, just skip it entirely
(please do not feel offended by me posting it here - no bad intentions
intended, no patronizing, I just want to avoid wasted efforts). If you
do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions of patchset, under or above your Signed-off-by tag, unless
patch changed significantly (e.g. new properties added to the DT
bindings). Tag is "received", when provided in a message replied to you
on the mailing list. Tools like b4 can help here ('b4 trailers -u ...').
However, there's no need to repost patches *only* to add the tags. The
upstream maintainer will do that for tags received on the version they
apply.
