title: Qualcomm QPNP PMIC Temperature Alarm

maintainers:
  - Bjorn Andersson <bjorn.andersson@linaro.org>

description:
  QPNP temperature alarm peripherals are found inside of Qualcomm PMIC chips
  that utilize the Qualcomm SPMI implementation. These peripherals provide an
  interrupt signal and status register to identify high PMIC die temperature.
