Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `i2c-alias-pool` property is artificially restricted to a maximum of 2 items, breaking validation for standard dual-link camera configurations.

dt-bindings: media: i2c: add MAX9296A, MAX96716A, MAX96792A

This commit introduces device tree bindings for the Maxim MAX9296A, MAX96716A,
and MAX96792A GMSL to CSI-2 deserializers. It defines constraints for the
various supported properties, including ports, power supplies, and the I2C
address translator layout.

[Severity: Medium]
Will this limit of 2 items break validation for standard dual-link camera
configurations?

A typical setup with two GMSL links often includes two serializers and two
image sensors. Such a configuration would require at least 4 I2C aliases in
the pool to translate all remote peripheral addresses.

Does this constraint incorrectly map to the number of GMSL links rather than
the expected number of remote I2C devices?
