-Qualcomm QPNP PMIC Temperature Alarm
-
-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.
-
-Required properties:
-- compatible:      Should contain "qcom,spmi-temp-alarm".
-- reg:             Specifies the SPMI address.
-- interrupts:      PMIC temperature alarm interrupt.
-- #thermal-sensor-cells: Should be 0. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
-
-Optional properties:
-- io-channels:     Should contain IIO channel specifier for the ADC channel,
-                   which report chip die temperature.
-- io-channel-names: Should contain "thermal".
-
-Example:
-
-       pm8941_temp: thermal-alarm@2400 {
-               compatible = "qcom,spmi-temp-alarm";

-               interrupts = <0 0x24 0 IRQ_TYPE_EDGE_RISING>;
-               #thermal-sensor-cells = <0>;
-
-               io-channels = <&pm8941_vadc VADC_DIE_TEMP>;
