1 * DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
3 On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
4 sensors (THS) which are the analog circuits for measuring temperature (Tj)
8 - compatible : "renesas,<soctype>-thermal",
9 Examples with soctypes are:
10 - "renesas,r8a7795-thermal" (R-Car H3)
11 - "renesas,r8a7796-thermal" (R-Car M3-W)
12 - "renesas,r8a77965-thermal" (R-Car M3-N)
13 - reg : Address ranges of the thermal registers. Each sensor
14 needs one address range. Sorting must be done in
15 increasing order according to datasheet, i.e.
17 - clocks : Must contain a reference to the functional clock.
18 - #thermal-sensor-cells : must be <1>.
22 - interrupts : interrupts routed to the TSC (3 for H3, M3-W and M3-N)
23 - power-domain : Must contain a reference to the power domain. This
24 property is mandatory if the thermal sensor instance
25 is part of a controllable power domain.
