Description:
|
|
The "cells" folder contains one file per cell exposed by the
|
|
NVMEM device. The name of the file is: "<name>@<byte>,<bit>",
|
|
with <name> being the cell name and <where> its location in
|
|
the NVMEM device, in hexadecimal bytes and bits (without the
|
|
'0x' prefix, to mimic device tree node names). The length of
|
|
the file is the size of the cell (when known). The content of
|
|
the file is the binary content of the cell (may sometimes be
|
|
ASCII, likely without trailing character).
|
|
Note: This file is only present if CONFIG_NVMEM_SYSFS
|
|
is enabled.
|
