-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@...0 {
- compatible = "qcom,spmi-temp-alarm";
- reg = <0x2400>;
- interrupts = <0 0x24 0 IRQ_TYPE_EDGE_RISING>;
- #thermal-sensor-cells = <0>;
-
- io-channels = <&pm8941_vadc VADC_DIE_TEMP>;
- io-channel-names = "thermal";
- };
-
- thermal-zones {
- pm8941 {
- polling-delay-passive = <250>;
- polling-delay = <1000>;
-
- thermal-sensors = <&pm8941_temp>;
-
- trips {
- stage1 {
- temperature = <105000>;
- hysteresis = <2000>;
- type = "passive";
- };
- stage2 {
- temperature = <125000>;
- hysteresis = <2000>;
- type = "critical";
- };
- };
- };
- };
