Newer meson PWM IPs support constant and polarity bits. Support them to correctly implement constant and inverted output levels. Using constant bit allows to have truly stable low or high output level. Since hi and low regs internally increment its values by 1 just writing zero to any of them gives 1 clock count impulse. If constant bit is set zero value in hi and low regs is not incremented. Using polarity bit instead of swapping hi and low reg values allows to correctly identify inversion in .get_state().

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 reStructuredText 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.
