v3 cover Add DT bindings and device tree nodes for TSENS in SC7280

Adding compatible string in TSENS dt-bindings, device node for TSENS controller and critical interrupt support, Thermal zone, cooling maps support and changing Hysteresis value for critical trip point, adding cooling-cells property.

Changes:
1) Adding sensors according to sensor index rules under thermal-zones.
2) Changing Hysteresis, as it is not needed for critical trip point, when it reaches critical threshold system will go for shutdown.
3) Adding cooling-cells property under cpus node.

Re: [PATCH V3 3/3] arm64: dts: qcom: SC7280: Add thermal zone support

Quoted 3 lines · Rajeshwari

Adding thermal zone, cooling maps support and changing hysteresis value for critical trip point in SC7280. Hysteresis is not needed for critical trip point, when it reaches critical threshold system will go for shutdown.

This patch doesn't change any hysteresis values, it adds them. As commented on v2, the sentence about the hysteresis doesn't add any value IMO, just remove it, or at least explain in a reply why you think it is valuable.

The node name should use dashes as separator, not underscores, i.e. it should be 'cpu-crit'. Applicable to all critical trip points.
