In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.

This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.

The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

- * This code is intended for developer use to convert a CrOS EC OS
- * "gpio.inc" file into the expected device-tree format for Zephyr.
- * The only use of it is to do a proof-of-concept build of a CrOS EC
- * device using Zephyr OS, as Zephyr-only devices won't have a
- * equivalent CrOS EC build.
- *
- * It does not handle all cases (i.e., low voltage selection), and
- * some manual modifications to the output may be required.
- *
- **********************************************************************
- * DO NOT CREATE TESTS, SYSTEMS, OR INFRASTRUCTURE WHICH RELIES ON    *
- * THIS CODE.  It's seriously ugly code that's probably prone to      *
- * breakage.  It leaks memory.  In other words, consider it           *
- * "contrib-quality" code that should be deleted one day (once we are *
- * no longer doing proof-of-concept Zephyr builds).                   *
- **********************************************************************
- *
- * To compile:
- *   gcc -Iboard/${BOARD} -std=gnu11 util/gpios_to_zephyr_dts.c \
- *       -o /tmp/print_gpios
- *
- * Then run /tmp/print_gpios and paste the result into your gpio DTS
- * overlay.
