[RFC,5/5] ARM: dts: stm32: Add Octavo OSD32MP1-RED board
Commit Message
Add support for the Octavo OSD32MP1-RED development board.
General features:
- STM32MP157C
- 512MB DDR3
- CAN-FD
- HDMI
- USB-C OTG
- UART

This is made with great inspiration from Neeraj Dantu's work:
https://raw.githubusercontent.com/octavosystems/OSD32MP1-RED-Device-tree/main/linux-v5.10-r0/stm32mp157c-osd32mp1-red.dts
So what copyright is needed here?
And author?
Still need to test ethernet and HDMI, thats why I have done this a RFC.

hum maybe Rob, or Krzystof will have a better answer than me but I would
say that only your name is enough. It's boards descriptions based on
common binding so at the end if 2 boards are quite similar their DT will
be similar. Not sure, but adding Neeraj as author could impose to him a
kind of responsibility to this file, and you have to check this point
with him if plan to add him.
