Re: [PATCH v2 1/3] dt-bindings: Add Device Tree binding for ST M24LR control interface

Hi Krzysztof,

Thank you for your review.

> Drop quotes. So this is I2C mux or EEPROM?

The system parameter sector and the EEPROM do not share a continuous address
space, each starts at address 0 and spans its own internal region. This
overlapping addressing creates ambiguity if treated as a single memory space.

Additionally, there's a synchronization issue: during multi-page writes to
the EEPROM, if a control command (e.g., a lock) is issued mid-operation,
it may result in partial or inconsistent writes.

To address both challenges, the driver uses a mux-based design:

1- The m24lr_ctl driver acts as a gate for EEPROM access.

2- It provides exclusive, serialized access and handles the control interface.

3- The EEPROM itself is exposed as a child node using the standard at24 driver.

This separation ensures reliable operation and a clean, maintainable
architecture.

Given the above, I'm unsure if placing it under eeprom/ is the best choice.
Would you suggest still placing it eeprom or under somewhere else maybe i2c/
(e.g., i2c/i2c-mux-stm24lr.yaml)?
