[ Upstream commit 4cf2ddf16e175ee18c5c29865c32da7d6269cf44 ]
Starting with commit d92ed2c9d3ff ("thermal: imx: Use driver's local
data to decide whether to run a measurement") this driver stared using
irq_enabled flag to make decision to power on/off the thermal
core. This triggered a regression, where after reaching critical
temperature, alarm IRQ handler set irq_enabled to false, disabled
thermal core and was not able read temperature and disable cooling
sequence.
In case the cooling device is "CPU/GPU freq", the system will run with
reduce performance until next reboot.
To solve this issue, we need to move all parts implementing hand made
runtime power management and let it handle actual runtime PM framework.
Fixes: d92ed2c9d3ff ("thermal: imx: Use driver's local data to decide whether to run a measurement")

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.
