i.MX7ULP has TPM(Low Power Timer/Pulse Width Modulation Module) inside, it can support multiple PWM channels, all the channels share same counter and period setting, but each channel can configure its duty and polarity independently. There are several TPM modules in i.MX7ULP, the number of channels in TPM modules are different, it can be read from each TPM module's PARAM register.

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.
