Depending on the version of the tsens IP, there can be 1 (upper/lower
threshold), 2 (upper/lower + critical threshold) or 3 (upper/lower +
critical + zero degree) interrupts. This patch series only introduces
support for a single interrupt (upper/lower).
I used the names tsens0, tsens1 to encapsulate the controller instance
since some SoCs have 1 controller, others have two. So we'll end up
with something like the following in DT:
tsens0: thermal-sensor@c263000 {
compatible = "qcom,sdm845-tsens", "qcom,tsens-v2";
reg = <0 0x0c263000 0 0x1ff>, /* TM */
<0 0x0c222000 0 0x1ff>; /* SROT */
#qcom,sensors = <13>;
interrupts = <GIC_SPI 506 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 508 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "tsens0", "tsens0-critical";
#thermal-sensor-cells = <1>;
};
tsens1: thermal-sensor@c265000 {
compatible = "qcom,sdm845-tsens", "qcom,tsens-v2";
reg = <0 0x0c265000 0 0x1ff>, /* TM */
<0 0x0c223000 0 0x1ff>; /* SROT */
#qcom,sensors = <8>;
interrupts = <GIC_SPI 507 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 509 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "tsens1", "tsens1-critical";
#thermal-sensor-cells = <1>;
}
Does that work?
