-Subject: [PATCH] Reduce noise from rpi poe hat fan
-
-This adds 2 extra states, at 40c and 45c, with PWM of 31 and 63 (out
-of 255) for the rpi poe hat fan.  This significantly improves user
-experience by providing a smoother ramp up of the fan, from a pwm 0
-to 31 to 63 then finally to 150, and additionally makes it very easy
-for users to further tweak the values as needed for their specific
-application.
-
-The possible concerns I have are that a hysteresis of 2000 (2c) could
-be too narrow, and that running the fan more at a reduced temperature
-(40000 - 40c) could cause problems.
