[PATCH v3 0/4] dt-bindings: Convert TI TPS65217 to DT schema

[PATCH v3 0/4] dt-bindings: Convert TI TPS65217 to DT schema

[Eduard Bostina]

This series converts the Texas Instruments TPS65217 PMIC bindings to DT
schema.

Changes in v3:
- Added 'unevaluatedProperties' to the 'charger' and 'pwrbutton' nodes.
- Renamed the example node to 'pmic@24' and added the rest of the
  properties and nodes to it.
- Dropped 'regulator-compatible' from the schema. The property is
  deprecated, so the regulator nodes are now named after the strings the
  driver matches on and the DTS is updated accordingly.

Link to v2:

[PATCH v3 1/4] ARM: dts: ti: am335x-guardian: Drop unused isink-en property

[Eduard Bostina]

The 'isink-en' property is not documented and not read by any driver,
so remove it from the TPS65217 backlight node.

[PATCH v3 2/4] ARM: dts: Rename the TPS65217 regulator nodes

[Eduard Bostina]

The TPS65217 regulator nodes are named regulator@0 to regulator@6 and
rely on the deprecated 'regulator-compatible' property to be matched
against the driver, which looks for "dcdc1" to "ldo4".

Documentation/devicetree/bindings/regulator/tps65217.txt states the
regulators must be named dcdc[1-3] and ldo[1-4].

Rename the nodes accordingly and drop 'regulator-compatible' along with
the unit addresses it made necessary.

[PATCH v3 4/4] dt-bindings: leds: backlight: Convert TPS65217 to DT schema

[Eduard Bostina]

Convert the Texas Instruments TPS65217 bindings to DT schema.

During the conversion, the following updates were made:
- Documented the 'regulators', 'charger' and 'pwrbutton' child nodes,
  which are used by the boards but were missing from the old txt
  binding.
- Documented the 'interrupts', 'interrupt-controller', '#interrupt-cells'
  and 'ti,pmic-shutdown-controller' properties, which are used by the
  am335x boards and read by the driver.

Re: [PATCH v3 4/4] dt-bindings: leds: backlight: Convert TPS65217 to DT schema

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The patch converts the TPS65217 backlight binding to a comprehensive PMIC schema but fails to delete the existing `regulator/tps65217.txt` binding, resulting in duplicate bindings.
- [Medium] The binding adds interrupt controller capabilities but omits `interrupt-controller` and `#interrupt-cells` from the `required` list.

dt-bindings: leds: backlight: Convert TPS65217 to DT schema

This commit converts the Texas Instruments TPS65217 backlight binding to
DT schema, adding child nodes for regulators, charger, and pwrbutton,
as well as documenting interrupt and shutdown controller properties.

[Severity: Medium]
This schema defines a comprehensive PMIC with regulators and chargers
rather than just a backlight, but it is placed in the leds/backlight
directory. Should this be moved to a more central MFD or regulator schema
location?

Additionally, it appears the existing regulator binding documentation at
Documentation/devicetree/bindings/regulator/tps65217.txt was not deleted
in this patch, leaving duplicate bindings for the ti,tps65217 compatible
string. Should that file be removed as part of this conversion so schema
validation is not split and inconsistent?

> +    unevaluatedProperties: false
> +
> +required:
> +  - compatible
> +  - reg

[Severity: Medium]
Because this binding allows the device to act as an interrupt controller,
do interrupt-controller and #interrupt-cells need to be included in this
required list?

The device tree binding guidelines indicate that when hardware provides
these capabilities, the corresponding properties must be required so
incomplete device tree nodes don't silently pass validation.

Re: [PATCH v3 3/4] dt-bindings: input: Convert TI TPS65217 power button to DT schema

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:

Pre-existing issues:
- [High] Missing NULL check on `dev_get_regmap` can lead to a kernel panic in the IRQ handler.
- [High] The driver incorrectly masks `platform_get_irq()` error codes with `-EINVAL`, breaking probe deferral.

dt-bindings: input: Convert TI TPS65217 power button to DT schema

Convert the Texas Instruments TPS65217 and TPS65218 Power Button
bindings to DT schema.

drivers/input/misc/tps65218-pwrbutton.c:tps6521x_pb_probe() {
        ...
        pwr->regmap = dev_get_regmap(dev->parent, NULL);
        ...
}

[Severity: High]
This isn't a bug introduced by this patch, but does this code need to check
if pwr->regmap is NULL?

If dev_get_regmap() returns NULL due to an incomplete device tree, it seems
this could lead to a kernel panic during an interrupt when tps6521x_pb_irq()
dereferences it:

drivers/input/misc/tps65218-pwrbutton.c:tps6521x_pb_irq() {
        ...
        error = regmap_read(pwr->regmap, tps_data->reg_status, &reg);
        ...
}


drivers/input/misc/tps65218-pwrbutton.c:tps6521x_pb_probe() {
        ...
        irq = platform_get_irq(pdev, 0);
        if (irq < 0)
                return -EINVAL;
        ...
}

[Severity: High]
This is also a pre-existing issue, but does masking the return value of
platform_get_irq() break probe deferral?

If platform_get_irq() returns -EPROBE_DEFER, converting the error to -EINVAL
prevents the driver core from handling the deferral and retrying later.

Why is sashiko pointing out driver issues on a DT binding patch? This 
series doesn't even touch the driver. This seems to be a re-occurring 
problem.
