The new patch to sysfs-interface (below) includes it. I did it that way because both sets of changes modify a common part of the file and the second patch might have been rejected because of that. Summary of what the patch does: 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. A patch to chipset drivers follows. --- linux-2.6.0-test9/Documentation/i2c/sysfs-interface.orig Sun Nov 16 19:51:12 2003 +++ linux-2.6.0-test9/Documentation/i2c/sysfs-interface Sun Nov 16 19:57:41 2003 @@ -68,9 +68,7 @@ Fixed point XXXXX, divide by 1000 to get Amps.
