-= NVMEM(Non Volatile Memory) Data Device Tree Bindings =
-
-This binding is intended to represent the location of hardware
-configuration data stored in NVMEMs like eeprom, efuses and so on.
-
-On a significant proportion of boards, the manufacturer has stored
-some data on NVMEM, for the OS to be able to retrieve these information
-and act upon it. Obviously, the OS has to know about where to retrieve
-these data from, and where they are stored on the storage device.
-
-This document is here to document this.
-
-= Data providers =
-Contains bindings specific to provider drivers and data cells as children
-of this node.
-
-Optional properties:
- read-only: Mark the provider as read only.
-
-= Data cells =
-These are the child nodes of the provider which contain data cell
-information like offset and size in nvmem provider.
-
-Required properties:
-reg: specifies the offset in byte within the storage device.
-
-Optional properties:
-
-bits: Is pair of bit location and number of bits, which specifies offset
- in bit and number of bits within the address range specified by reg property.
- Offset takes values from 0-7.
-
-For example:
-
- /* Provider */
- qfprom: qfprom@700000 {
- ...
-
- /* Data cells */
- tsens_calibration: calib@404 {
- reg = <0x404 0x10>;
- };
-
- tsens_calibration_bckp: calib_bckp@504 {
- reg = <0x504 0x11>;
- bits = <6 128>
- };
-
- pvs_version: pvs-version@6 {
- reg = <0x6 0x2>
- bits = <7 2>
- };
-
- speed_bin: speed-bin@c{
- reg = <0xc 0x1>;
- bits = <2 3>;
-
- };
- ...
- };
-
-= Data consumers =
-Are device nodes which consume nvmem data cells/providers.
-
-Required-properties:
-nvmem-cells: list of phandle to the nvmem data cells.
-nvmem-cell-names: names for the each nvmem-cells specified. Required if
- nvmem-cells is used.
-
-Optional-properties:
-nvmem : list of phandles to nvmem providers.
-nvmem-names: names for the each nvmem provider. required if nvmem is used.
-
-For example:
-
- tsens {
- ...
- nvmem-cells = <&tsens_calibration>;
- nvmem-cell-names = "calibration";
- };
