What: /sys/bus/nvmem/devices/.../cells/<cell-name>
Date: May 2023
KernelVersion: 6.5
Contact: Miquel Raynal <miquel.raynal@bootlin.com>
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.
Example::
hexdump -C /sys/bus/nvmem/devices/1-00563/cells/product-name@d,0
