As a second global reset, the GRF is not reset, the iomux and pull of PWM pin is still keeping, but PWM controller is reset, PWM pin goes into input mode. However, the pull is still none changed in kernel, which can cause voltage problems, so should always keep the PWM pin pull down mode, with 0~50 μA power increase.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
