Subject: Re: [PATCH v9 0/9] Add simple NVMEM Framework via regmap.
Date: Sun, 9 Aug 2015 17:19:16 +0200 [thread overview]

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
