[PATCH V3] ARM: dts: stm32: Add DH Electronics DHCOM SoM and PDK2 board
Marek Vasut

Fri Jan 24 18:39:16 CET 2020
Add support for DH Electronics DHCOM SoM and PDK2 rev. 400 carrier
board. This is an SoM with STM32MP15xx and an evaluation kit. The
baseboard provides Ethernet, UART, USB, CAN and optional display.

V2: Rebase on u-boot/master and multi-board changes.
V3: - Fold in changes from Patrick to scrub more ST-board bits
- Rename DTs to stm32mp15xx-dhcom* as the devkit can host
any of the STM32MP1 SoCs
