Commit22337b9102("arm64: dts: qcom: sc7180: Changed polling mode in Thermal-zones node") sets both 'polling-delay' and 'polling-delay-passive' to zero with the rationale that TSENS interrupts are enabled. A TSENS interrupt fires when the temperature of a thermal zone reaches a trip point, which makes regular polling below the passive trip point temperature unnecessary. However the situation is different when passive cooling is active, regular polling is still needed to trigger a periodic evaluation of the thermal zone by the thermal governor. Change 'polling-delay-passive' back to the original value of 250 ms. Commit2315ae70af("arm64: dts: qcom: sc7180: Add gpu cooling support") recently changed the value for the GPU thermal zones from zero to 100 ms, also set it to 250 ms for uniformity. If some zones really need different values these can be changed in dedicated patches.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
