ChangeSet 1.1496.9.3, 2003/12/04 13:41:40-08:00, khali at linux-fr.org [PATCH] I2C: sysfs interface documentation 1* No more current hysteresis value. I don't think we ever saw a chip which monitors current, and if we ever do, I would be very, very surprised if it would have an hysteresis value. 2* Temperature input and max can have 4 values. [from the previous patch] 3* Split temperature min and hysteresis into two separate files. 4* New file temp_crit. [from previous patch] The new file temp_crit is subject to change later as we decide more precisely how we want to handle values that are common to more than one temperature channels.
