Algy Tynan af88d65e86 mimxrt: Add ALT11 pin mode support for MIMXRT1176.
This adds support for the ALT11 alternate function mode on MIMXRT1176
MCUs, enabling FLEXPWM channels on GPIO_AD pins that were previously
unavailable for PWM use.

Changes:
- Add PIN_AF_MODE_ALT11 enum to pin.h
- Add ALT11 column to MIMXRT1176_af.csv with FLEXPWM mappings
- Enables FLEXPWM1-4 on GPIO_AD_06 through GPIO_AD_21

This change only affects MIMXRT1176-based boards (MIMXRT1170_EVK and
PHYBOARD_RT1170). Other MIMXRT family chips use alternate function
modes ALT0-ALT9 and are not affected.

Tested on MIMXRT1176 hardware with PWM output on GPIO_AD_14
(FLEXPWM3_PWM0_X).

MicroPython Documentation

The MicroPython documentation can be found at: http://docs.micropython.org/en/latest/

The documentation you see there is generated from the files in the docs tree: https://github.com/micropython/micropython/tree/master/docs

Building the documentation locally

If you're making changes to the documentation, you may want to build the documentation locally so that you can preview your changes.

Install Sphinx and sphinx_rtd_theme, preferably in a virtualenv:

 pip install sphinx
 pip install sphinx_rtd_theme

In micropython/docs, build the docs:

make html

You'll find the index page at micropython/docs/build/html/index.html.

Documentation autobuild

For a more convenient development experience, you can use sphinx-autobuild to automatically rebuild and serve the documentation when you make changes:

pip install sphinx-autobuild

Then run from the micropython/docs directory:

sphinx-autobuild . build/html

This will start a local web server (typically at http://127.0.0.1:8000) and automatically rebuild the documentation whenever you save changes to the source files.

Having readthedocs.org build the documentation

If you would like to have docs for forks/branches hosted on GitHub, GitLab or BitBucket an alternative to building the docs locally is to sign up for a free https://readthedocs.org account. The rough steps to follow are:

  1. sign-up for an account, unless you already have one
  2. in your account settings: add GitHub as a connected service (assuming you have forked this repo on github)
  3. in your account projects: import your forked/cloned micropython repository into readthedocs
  4. in the project's versions: add the branches you are developing on or for which you'd like readthedocs to auto-generate docs whenever you push a change

PDF manual generation

This can be achieved with:

make latexpdf

but requires a rather complete install of LaTeX with various extensions. On Debian/Ubuntu, try (1GB+ download):

apt install texlive-latex-recommended texlive-latex-extra texlive-xetex texlive-fonts-extra cm-super xindy
