The projects aims to practice how to interface a real hardware with the driver model of the Linux kernel. The idea here is to provide a char device under /dev/char_at24. There exists a mainline at24 driver in drivers/misc/eeprom/at24.c which in certains aspects I took as reference. However, this differ in the sense that the other one uses the nvmem subsystem as interface for the mememory, apart that it uses the acpi for discovering. In this example, I use the device tree for discovering and the char interface for read/write ops. In addition, I support only at24c256 memory.

The AT24 are EEPROMs compatible with the programming model of Atmel AT24.

This is not a production driver
