This patch adds the device tree to support Google Coral Edge TPU,
historicaly named as fsl-imx8mq-phanbell, a computer on module
which can be used for AI/ML propose.
It introduces a minimal enablement support for this module and
was totally based on the NXP i.MX 8MQ EVK board and i.MX 8MQ Phanbell
Google Source Code for Coral Edge TPU Mendel release:
https://coral.googlesource.com/linux-imx/
Tested components:
- PMIC;
- USB-C OTG;
- USB-C PWR;
- micro-USB;
- USB.
