[PATCH 0/3] Add control driver for ST M24LR RFID/NFC EEPROM chips

[Abd-Alrhman Masalkhi <abd.masalkhi@gmail.com>]

This patch series adds support for the control interface of
STMicroelectronics M24LR RFID/NFC EEPROM devices, such as M24LR04E-R.

The device exposes two I2C addresses: one for the control interface
and another for EEPROM memory. To support this design, the driver
acts as an I2C mux (gate), exposing the EEPROM as a child node
handled by the standard at24 driver. Using the mux not only enables
clean separation of functions but also allows synchronize access to
the device.

Patches:
  - Patch 1: Adds Device Tree binding for the control interface.
  - Patch 2: Adds the sysfs-based control driver.
  - Patch 3: Adds a MAINTAINERS entry for the driver.

Tested on: m24lr04e-r
