   1 Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
   2
   3 Required parameters:
   4 -------------------
   5
   6 compatible :    st,<SoC>-<module>-thermal; should be one of:
   7                   "st,stih415-sas-thermal",
   8                   "st,stih415-mpe-thermal",
   9                   "st,stih416-sas-thermal"
  10                   "st,stih416-mpe-thermal"
  11                   "st,stid127-thermal" or
  12                   "st,stih407-thermal"
  13                 according to the SoC type (stih415, stih416, stid127, stih407)
  14                 and module type (sas or mpe). On stid127 & stih407 there is only
  15                 one die/module, so there is no module type in the compatible
  16                 string.
  17 clock-names :   Should be "thermal".
  18                   See: Documentation/devicetree/bindings/resource-names.txt
  19 clocks :        Phandle of the clock used by the thermal sensor.
  20                   See: Documentation/devicetree/bindings/clock/clock-bindings.txt
  21
  22 Optional parameters:
  23 -------------------
  24
  25 reg :           For non-sysconf based sensors, this should be the physical base
  26                 address and length of the sensor's registers.
  27 interrupts :    Standard way to define interrupt number.
  28                 Interrupt is mandatory to be defined when compatible is
  29                 "stih416-mpe-thermal".
  30                   NB: For thermal sensor's for which no interrupt has been
  31                   defined, a polling delay of 1000ms will be used to read the
  32                   temperature from device.

  34 Example:
  35
  36         temp1@fdfe8000 {
  37                 compatible      = "st,stih416-mpe-thermal";
  38                 reg             = <0xfdfe8000 0x10>;
  39                 clock-names     = "thermal";
  40                 clocks          = <&clk_m_mpethsens>;
  41                 interrupts      = <GIC_SPI 23 IRQ_TYPE_NONE>;
  42         };
