-= NVMEM(Non Volatile Memory) Data Device Tree Bindings =
2
-
3
-This binding is intended to represent the location of hardware
4
-configuration data stored in NVMEMs like eeprom, efuses and so on.
5
-
6
-On a significant proportion of boards, the manufacturer has stored
7
-some data on NVMEM, for the OS to be able to retrieve these information
8
-and act upon it. Obviously, the OS has to know about where to retrieve
9
-these data from, and where they are stored on the storage device.

-= Data providers =
14
-Contains bindings specific to provider drivers and data cells as children
15
-of this node.

17
-Optional properties:
18
- read-only: Mark the provider as read only.

-= Data cells =
21
-These are the child nodes of the provider which contain data cell
22
-information like offset and size in nvmem provider.
23

24
-Required properties:
25
-reg: specifies the offset in byte within the storage device.
26
-
27
-Optional properties:
28
-
29
-bits: Is pair of bit location and number of bits, which specifies offset
30
- in bit and number of bits within the address range specified by reg property.
31
- Offset takes values from 0-7.

-For example:
34
-
35
- /* Provider */
36
- qfprom: qfprom@700000 {

39

65
-Required-properties:
66
-nvmem-cells: list of phandle to the nvmem data cells.
67
-nvmem-cell-names: names for the each nvmem-cells specified. Required if

- nvmem-cells is used.

-nvmem : list of phandles to nvmem providers.
