   7         help
   8           Generic Thermal Sysfs driver offers a generic mechanism for
   9           thermal management. Usually it's made up of one or more thermal
  10           zone and cooling device.
  11           Each thermal zone contains its own temperature, trip points,
  12           cooling devices.
  13           All platforms with ACPI thermal support can use this driver.
  14           If you want this support, you should say Y or M here.

  23           Thermal subsystem will issue a graceful shutdown when
  24           critical temperatures are reached using orderly_poweroff(). In
  25           case of failure of an orderly_poweroff(), the thermal emergency
  26           poweroff kicks in after a delay has elapsed and shuts down the system.
  27           This config is number of milliseconds to delay before emergency
  28           poweroff kicks in. Similarly to the critical trip point,
  29           the delay should be carefully profiled so as to give adequate

 437           temperature sensor embedded in Tango chips since the SMP8758.
 438           This sensor only generates a 1-bit signal to indicate whether
 439           the die temperature exceeds a programmable threshold.

 448           This enables a thermal sysfs driver for Qualcomm plug-and-play (QPNP)
 449           PMIC devices. It shows up in sysfs as a thermal sensor with multiple
 450           trip points. The temperature reported by the thermal sensor reflects the
 451           real time die temperature if an ADC is present or an estimate of the

 460           is read via IIO framework and the channel information is provided
 461           to this driver. This driver reports the temperature by reading ADC
 462           channel and converts it to temperature based on lookup table.
