+Each sensor has its own critical limit. Additionally, there is a relative
+hysteresis value common to both critical limits. To make life easier to
+user-space applications, two absolute values are exported, one for each
+channel, but these values are of course linked. Only the local hysteresis
+can be set from user-space, and the same delta applies to the remote
+hysteresis.
The lm95245 driver can change its update interval to a fixed set of values.
It will round up to the next selectable interval. See the datasheet for exact
