[PATCH 0/7] arm64: dts: qcom: Add 3 new devices

[Adam Skladowski]

Introduce support for 3 new devices:
- Motorola Moto One based on MSM8953
- LeEco Le2 based on MSM8976
- Xiaomi Redmi 9T based on SM6115

Device trees besides enabling most of supported hardware also wires power to
subsystems like MDSS even if those are not enabled to lower maintenance burden
on out of tree forks.

[PATCH 3/7] arm64: dts: qcom: Add Motorola One

[Adam Skladowski]

Add a devicetree for the Motorola One smartphone, which is based
on the Jacala/MSM8953 SoC.

Supported functionality as of this initial submission:
* I2C peripherals (Touchscreen,NFC)
* Power Button, Volume Keys
* Regulators (PM8953)
* Remoteprocs (ADSP, MPSS, WCNSS)
* USB

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.

Re: [PATCH 3/7] arm64: dts: qcom: Add Motorola One

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 5 potential issue(s) to consider:
- [High] Missing `vdd_l23-supply` parent supply linkage for the PM8953 L23 regulator.
- [High] Missing `vcc-supply` for the Novatek touchscreen.
- [High] The `fcs,fusb302` device specifies an incorrect interrupt polarity (`IRQ_TYPE_EDGE_RISING`) for its INT_N pin.
- [Medium] Mismatch between the configured Audio Front End (AFE) DAI, physical GPIO pin functions, and unused pinctrl nodes for the MI2S interface.
- [Low] Misleading node name `pn533@28` for an NXP NCI compatible device.

arm64: dts: qcom: Add Motorola One

Add a devicetree for the Motorola One smartphone, which is based
on the Jacala/MSM8953 SoC.

[Severity: High]
The FUSB302 INT_N pin is an active-low open-drain output, but this interrupt
is configured as IRQ_TYPE_EDGE_RISING.

Will the host miss interrupts since the FUSB302 holds the line low until
cleared, causing a deadlock while the host waits for a rising edge?

Does this regression break Type-C functionality like PD negotiation and
role swapping?

[Severity: High]
Does the novatek,nt36672a-ts driver also require a vcc-supply to be
specified here?

Omitting it means devm_regulator_bulk_get() might fall back to a dummy
regulator, preventing the physical analog power rail from being enabled.
Does this cause a regression where touchscreen initialization fails?

[Severity: Low]
Since the compatible string specifies a generic nxp,nxp-nci-i2c controller,
should this node be named with a generic device class like nfc@28 instead of
a specific chip name like pn533@28 to avoid a naming regression?

[Severity: Medium]
Is the Audio Front End configured correctly here?

This q6afedai node specifies QUATERNARY_MI2S_RX, but the mi2s_sec_act pinctrl
states added below configure pins 135-138 with the sec_mi2s function.

Could this interface mismatch cause an audio regression on this port?

[Severity: High]
Is there a missing vdd_l23-supply linkage in this parent supply mapping block?

Without mapping vdd_l23-supply to pm8953_s3, the regulator framework is
unaware of the dependency. If the system disables L1, L2, and L3, the PMIC
core might power down S3, starving L23 of its input voltage.

Does this regression lead to a hardware brownout?

[Severity: Medium]
These secondary MI2S pinctrl states appear to be unreferenced dead code.
Should they be tied to the DAI node above to prevent a configuration
regression?

[PATCH 5/7] arm64: dts: qcom: Add LeEco Le2

[Adam Skladowski]

Add a devicetree for the LeEco Le2 smartphone, which is based
on the Eldarion/MSM8976 SoC.

Supported functionality as of this initial submission:
* I2C peripherals (Touchscreen,Audio amp, Haptics, Extcon, Led)
* Power Button, Volume Keys
* Regulators (PM8950)
* WLED (PMI8950)
* Remoteprocs (WCNSS)
* GPU

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.

Re: [PATCH 5/7] arm64: dts: qcom: Add LeEco Le2

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 6 potential issue(s) to consider:
- [High] Touchscreen and USB nodes are missing `pinctrl` properties, `reset-gpios`, and use invalid downstream interrupt flags.
- [High] The eMMC controller (`sdhc_1`) lacks required `non-removable` and `bus-width = <8>` properties.
- [Medium] Missing `no-map` property in the `cont_splash_mem` reserved-memory region.
- [Medium] Unimplemented features claimed in the commit message (Volume Down key and WLED).
- [Low] Attempting to delete a non-existent device tree node breaks the build.
- [Low] The `ramoops` node has a `reg` property but lacks a unit address in its node name.

Author: Adam Skladowski <a39.skl@gmail.com>

arm64: dts: qcom: Add LeEco Le2

This patch adds a devicetree for the LeEco Le2 smartphone based on the MSM8976
SoC. It claims support for peripherals such as I2C, Power/Volume keys,
regulators, WLED, WCNSS, and GPU.

> Supported functionality as of this initial submission:
> * I2C peripherals (Touchscreen,Audio amp, Haptics, Extcon, Led)
> * Power Button, Volume Keys

[Severity: Medium]
The commit message lists Volume Keys, but only the Volume Up key is defined
in the patch. Was the Volume Down key inadvertently omitted?

> * Regulators (PM8950)
> * WLED (PMI8950)

[Severity: Medium]
The commit message lists WLED, but the pmi8950_wled node below lacks
a status = "okay" property to enable it. Does the WLED function work as is?

[Severity: Low]
Does this node need a unit address in its name to match the reg property
(e.g., ramoops@9ff00000)? Without it, the device tree compiler will generate
a build warning.

[Severity: Low]
Could this /delete-node/ cause a fatal dtc build failure?

The memory@83000000 node does not appear to exist in the included
msm8976.dtsi or PMIC include files.

> +		};

[Severity: Medium]
Should the cont_splash_mem node include the no-map property?

Without it, the kernel maps the region as standard cacheable RAM, which can
cause speculative data aborts, caching issues, or visual corruption if the
bootloader leaves the display controller scanning out from this memory.

[Severity: High]
Does this use an invalid downstream interrupt flag? 

0x2008 is usually a downstream wakeup flag that the upstream kernel masks,
meaning it won't be recognized as a wakeup source.

Also, are the pinctrl-names, pinctrl-0, and reset-gpios properties missing
here? 

Without pinctrl, the interrupt pin (gpio65) lacks a pull-up, which can cause
an interrupt storm, and without reset-gpios, the controller might not probe
properly. The ts_int_default and ts_reset_active pinctrl states defined below
appear to be unused.

[Severity: High]
Is a pinctrl configuration missing for this interrupt pin?

[Severity: High]
Should this eMMC controller node include the non-removable and bus-width = <8>
properties?

Because it is not marked as non-removable, the MMC core may treat it as a
hot-pluggable SD card and poll for Card Detect, causing boot delays. Missing
the bus-width property can also degrade storage throughput by restricting it
to 4-bit or 1-bit mode.

[PATCH 7/7] arm64: dts: qcom: Add Xiaomi Redmi 9T

[Adam Skladowski]

Add a devicetree for the Xiaomi Redmi 9T smartphone, which is based
on the Bengal/SM6115 SoC.

Supported functionality as of this initial submission:

* Display via SimpleFB/SimpleDRM
* GPU
* I2C peripherals (Backlight)
* Power Button, Volume Keys
* Regulators
* Remoteprocs (ADSP, CDSP, MPSS)
* UFS/SDCARD
* USB

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.
