Hi Srinivas

The AT24 eeprom driver contains the comment:

        /*                                                                                               
         * Export the EEPROM bytes through sysfs, since that's convenient.                               
         * By default, only root should see the data (maybe passwords etc)                               
         */

and as you would expect from this:

# ls -l ./devices/platform/soc/soc:aips-bus@40000000/40066000.i2c/i2c-0/0-0050/eeprom
-rw------- 1 root root 512 Aug  9 10:16 ./devices/platform/soc/soc:aips-bus@40000000/40066000.i2c/i2c-0/0-0050/eeprom

The AT25 and the MAX6875 driver are the same.

However nvmem has different defaults:

# ls -l ./devices/platform/soc/soc:aips-bus@40000000/40066000.i2c/i2c-0/0-0050/0-00500/nvmem
-rw-r--r-- 1 root root 0 Aug  9 10:16 ./devices/platform/soc/soc:aips-bus@40000000/40066000.i2c/i2c-0/0-0050/0-00500/nvmem

Has this been considered and discussed?

Thanks
    Andrew
