   4 Subject: [PATCH] thermal/drivers/tsens: Allow configuring min and max trips
   5
   6 IPQ8074 and IPQ6018 dont support negative trip temperatures and support
   7 up to 204 degrees C as the max trip temperature.
   8
   9 So, instead of always setting the -40 as min and 120 degrees C as max
  10 allow it to be configured as part of the features.
