Re: [PATCH 1/9] ARM: dts: stm32: Add Engicam i.Core STM32MP1 SoM

Hi Jagan

On 2/28/21 4:52 PM, Jagan Teki wrote:

i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.

General features:

• STM32MP157A
• Up to 1GB DDR3L
• 4GB eMMC
• 10/100 Ethernet
• USB 2.0 Host/OTG
• I2S
• MIPI DSI to LVDS
• rest of STM32MP157A features

i.Core STM32MP1 needs to mount on top of Engicam baseboards for creating complete platform solutions.

Add support for it.
