From: Jim Cromie Date: Sun, 19 Oct 2008 03:27:35 +0000 (-0700) Subject: hwmon/pc87360 separate alarm files: add therm-min/max/crit-alarms X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=865c295360f61c2f3634fb1387b4468fdc8287da;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git hwmon/pc87360 separate alarm files: add therm-min/max/crit-alarms Adds therm-min/max/crit-alarm callbacks, sensor-device-attribute declarations, and refs to those new decls in the macro used to initialize the therm_group (of sysfs files) The thermistors use voltage channels to measure; so they don't have a fault-alarm, but unlike the other voltages, they do have an overtemp, which we call crit (by convention).
