[PATCH v3 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.

Changes in v3:
- Motorola One Touchscreen was removed as it doesn't work
- Leeco Le 2 gpio-keys node name was fixed
- Leeco Le 2 volume down key via pm8950 resin was added
- Redmi 9T Reviewed-by tag was added
- Adressed more Sashiko-bot warnings

- Link to v2: https://patch.msgid.link/20260820-next-patches-v2-0-7130d68183d9@gmail.com

Changes in v2:
- Adressed Sashiko-bot warnings
- Added Krzysztof's Acks
- Dropped confusing link from first vendor-prefix patch
- Removed ramoops nodes from Motorola and Leeco patches(now handled via lk2nd)
- Motorola One USB-C connector and FUSB302 is now fully wired and enabled
- Motorola One Touchscreen has been disabled due to panel power dependency
- Motorola One debug memory regions were removed
- Motorola One regulator setup values were ajusted
- Motorola One NFC now have more specific compatible
- All devices now have described reserved GPIOs and trimmed unused ones
- Leeco Le2 added missing pinctrls for peripheral IRQs
- Leeco Le2 OTG is no longer enabled as phy dependency is not enabled(need rework)
- Redmi 9T USB-C connector now is fully wired including pmi632 setup
- Redmi 9T nodes are sorted now
- Various changes to styling to keep nodes within single dts consistent

[PATCH v3 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.

[PATCH v3 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.

[PATCH v3 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.

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

arm64: dts: qcom: Add Xiaomi Redmi 9T

This commit adds the devicetree for the Xiaomi Redmi 9T smartphone, based on
the Bengal/SM6115 SoC. It defines memory regions, regulators, and enables
various peripherals like SimpleFB and remoteprocs.

> Supported functionality as of this initial submission:
> 
> * Display via SimpleFB/SimpleDRM
> * GPU
> * I2C peripherals (Backlight)

[Severity: Medium]
Is the commit message accurate about backlight support? The device tree marks
both the backlight-dsi and lm36923_bl nodes with status = "disabled", which
would prevent the driver from probing.

[Severity: Low]
Does this break alphabetical ordering in the Makefile? The hyphen character
comes before 'p' in ASCII, so sm6115-xiaomi-lemon.dtb should probably be
placed before sm6115p-lenovo-j606f.dtb to prevent future merge conflicts.

[Severity: Low]
Does this single-element brightness-levels array trigger a boot warning? In
led_bl_parse_levels(), the driver checks if there is more than 1 level and
emits a "Not enough levels defined" warning if only one is present.

[Severity: Low]
Is it necessary to enable the spi2 bus here? It appears to be enabled
without any child nodes or pinctrl configurations, which might hold
unnecessary power and clock resources.

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

[Severity: Medium]
The commit message mentions touchscreen support, but it appears the device
node is missing from the I2C buses in the device tree. Are the touchscreen
nodes missing from this submission?

[Severity: Low]
Will these node names cause dtbs_check warnings?

It looks like vph-pwr-regulator and otg-vbus do not match the required node
name pattern for fixed regulators in fixed-regulator.yaml. Should they
start with "regulator" to pass validation?

Are these I2C buses left empty because the intended touchscreen device node

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 4 potential issue(s) to consider:
- [High] The TUSB320 Type-C controller's interrupt is incorrectly configured with a rising edge trigger.
- [Medium] The GPU regulator `VDD_GFX` is marked `regulator-always-on`, which defeats dynamic power scaling.
- [Medium] WLED is claimed as supported but the pmi8950_wled node is left disabled.
- [Medium] The 'vdd_l9_l10_l13_l14_l15_l18-supply' property is missing from the pm8950 rpm_requests regulator node.

and regulators.

[Severity: High]
The TUSB320 INT_N interrupt signal is typically an active-low open-drain
output.

Will configuring it to trigger on a rising edge cause the driver to miss
Type-C events, since it would only process the interrupt when the hardware
deasserts the line?

[Severity: Medium]
Does setting regulator-always-on for the VDD_GFX regulator defeat the Adreno
GPU driver's dynamic power scaling?

This appears to keep the GPU rail powered even when idle or suspended.

[Severity: Medium]
The commit message lists WLED as supported, but this node lacks a
status = "okay" property.

Since pmi8950.dtsi defaults the WLED node to disabled, will the driver fail
to probe?

[Severity: Medium]
Are we missing the vdd_l9_l10_l13_l14_l15_l18-supply property here?

Without it, the regulator core might not be able to track the parent supply
for LDOs 9, 10, 13, 14, 15, and 18.
