RZ/G2M also has 3 interrupts routed to the TSC, but the list was not
updated to reflect this.
Just drop the list, as this is the case for this TSC variant in all
R-Car Gen3 and RZ/G2 SoCs.

* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
|
|
|
|
On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
|
|
sensors (THS) which are the analog circuits for measuring temperature (Tj)
|
|
inside the LSI.
|
|
|
|
Required properties:
|
|
- compatible : "renesas,<soctype>-thermal",
|
|
Examples with soctypes are:
|
|
- "renesas,r8a774a1-thermal" (RZ/G2M)
|
|
- "renesas,r8a7795-thermal" (R-Car H3)
|
|
- "renesas,r8a7796-thermal" (R-Car M3-W)
|
|
- "renesas,r8a77965-thermal" (R-Car M3-N)
|
|
- "renesas,r8a77980-thermal" (R-Car V3H)
|
|
- reg : Address ranges of the thermal registers. Each sensor
|
|
needs one address range. Sorting must be done in
|
|
increasing order according to datasheet, i.e.
|
|
TSC1, TSC2, ...
|
|
- clocks : Must contain a reference to the functional clock.
|
|
- #thermal-sensor-cells : must be <1>.
|
|
|
|
Optional properties:
|
|
|
|
- interrupts : interrupts routed to the TSC (must be 3).
|
|
- power-domain : Must contain a reference to the power domain. This
|
|
property is mandatory if the thermal sensor instance
|
|
is part of a controllable power domain.
|
|
|
|
Example:
|
|
|
|
tsc: thermal@e6198000 {
|
|
compatible = "renesas,r8a7795-thermal";
|
|
reg = <0 0xe6198000 0 0x100>,

|

|
|

|
|
<GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
|
|

|
