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?
