-Binding for Thermal Sensor for STMicroelectronics STM32 series of SoCs.
-
-On STM32 SoCs, the Digital Temperature Sensor (DTS) is in charge of managing an
-analog block which delivers a frequency depending on the internal SoC's
-temperature. By using a reference frequency, DTS is able to provide a sample
-number which can be translated into a temperature by the user.
-
-DTS provides interrupt notification mechanism by threshold. This mechanism
-offers two temperature trip points: passive and critical. The first is intended
-for passive cooling notification while the second is used for over-temperature
-reset.
-
-Required parameters:
--------------------
-
-compatible:    Should be "st,stm32-thermal"
-reg:           This should be the physical base address and length of the
-               sensor's registers.
-clocks:        Phandle of the clock used by the thermal sensor.
-                 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-clock-names:   Should be "pclk" for register access clock and reference clock.
-                 See: Documentation/devicetree/bindings/resource-names.txt
-#thermal-sensor-cells: Should be 0. See ./thermal.txt for a description.
-interrupts:    Standard way to define interrupt number.
-
-Example:
-
-       thermal-zones {
-               cpu_thermal: cpu-thermal {
-                       polling-delay-passive = <0>;
-                       polling-delay = <0>;
-
-                       thermal-sensors = <&thermal>;
-
-                       trips {
-                               cpu_alert1: cpu-alert1 {
-                                       temperature = <85000>;
-                                       hysteresis = <0>;
-                                       type = "passive";
-                               };
-
-                               cpu-crit: cpu-crit {
-                                       temperature = <120000>;
-                                       hysteresis = <0>;
-                                       type = "critical";
-                               };
-                       };
-
-                       cooling-maps {
-                       };
-               };
-       };
-
-       thermal: thermal@50028000 {
-               compatible = "st,stm32-thermal";
-               reg = <0x50028000 0x100>;
-               clocks = <&rcc TMPSENS>;
-               clock-names = "pclk";
-               #thermal-sensor-cells = <0>;
-               interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>;
