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,r8a774a1-thermal" (RZ/G2M)
11 - "renesas,r8a774b1-thermal" (RZ/G2N)
12 - "renesas,r8a7795-thermal" (R-Car H3)
13 - "renesas,r8a7796-thermal" (R-Car M3-W)
14 - "renesas,r8a77965-thermal" (R-Car M3-N)
15 - "renesas,r8a77980-thermal" (R-Car V3H)
16 - reg : Address ranges of the thermal registers. Each sensor
17 needs one address range. Sorting must be done in
18 increasing order according to datasheet, i.e.
20 - clocks : Must contain a reference to the functional clock.
21 - #thermal-sensor-cells : must be <1>.
25 - interrupts : interrupts routed to the TSC (must be 3).
26 - power-domain : Must contain a reference to the power domain. This
27 property is mandatory if the thermal sensor instance
28 is part of a controllable power domain.
