+= NVMEM in MTD =
+
+Config data for drivers is often stored in MTD devices. This binding
+define how such data can be represented in device tree.
+
+An MTD can be defined as an NVMEM provider by adding the `nvmem-provider`
+property to their node. Data cells can then be defined as child nodes
+of the partition as defined in nvmem.txt.
+
+Example:
+
+ flash@0 {
+ ...
+
+ partition@2 {
+ label = "art";
+ reg = <0x7F0000 0x010000>;
+ read-only;
+
+ nvmem-provider;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ eeprom@1000 {
+ label = "wmac-eeprom";
+ reg = <0x1000 0x1000>;
+ };
+ };
+ };
