[linux-yocto] [PATCH 07/12] misc/at24: Register memory accessor functions with of_memory_accessor

[Chandrakala Chavva]

From: Abhishek Paliwal <abhishek.paliwal at aricent.com>

From: Aaron Williams <aaron.williams at cavium.com>

The at24 module will now register its memory accessor functions with its
device tree entry so that other modules may call these functions based on
the device tree node.
