[Linux-stm32] [PATCH V2 6/6] ARM: dts: stm32: Add DH Electronics DHCOM STM32MP1 SoM and PDK2 board
Marek Vasut
marex at denx.de
Sun Jan 19 19:11:43 UTC 2020
Add support for DH Electronics DHCOM SoM and PDK2 rev. 400 carrier
board. This is an SoM with STM32MP157C and an evaluation kit. The
baseboard provides Ethernet, UART, USB, CAN and optional display.
