Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [Medium] Incomplete device tree binding schema rejects valid hardware configurations for SPI, I3C, and reset lines.
- [Low] Missing IIO subsystem mailing list in MAINTAINERS entry.
- [Low] Contradictory schema constraints for the `interrupts` property.

dt-bindings: Add InvenSense ICM-42370-p accelerometer

This commit adds device tree binding documentation for the InvenSense
ICM-42370-P 3-axis accelerometer. The device supports I2C, SPI, and I3C,
but this initial binding is geared towards I2C. The commit updates the
MAINTAINERS file with the new binding.

[Severity: Low]
Does this schema unnecessarily enforce interrupts as a strict requirement?

Since interrupts is listed in the required array, the dependency check 
for interrupt-names: [ interrupts ] above is dead logic. Also, since IIO
sensors typically support polling, making interrupts strictly mandatory 
might prevent valid polling-based hardware designs from passing validation.

[Severity: Medium]
Will this strict constraint actively reject valid hardware descriptions for
SPI, I3C, or reset lines?

The commit message mentions support for SPI, I3C, and resets, but since
standard SPI/I3C peripheral property $ref inclusions and the resets property
are missing, unevaluatedProperties: false will cause validation to fail when
standard properties like spi-max-frequency or resets are provided in the
device tree.

[Severity: Low]
Should this MAINTAINERS entry include the standard IIO subsystem mailing list?

Currently, it only lists a corporate mailing list, omitting 
linux-iio@vger.kernel.org which is typically mandatory for IIO entries. This
means patches modifying this binding will not be automatically CC'd to the 
subsystem list by get_maintainer.pl.
