Subject: [PATCH v2 3/6] arm64: dts: imx8mm: Add Engicam i.Core MX8M Mini SoM
Date: Mon, 21 Dec 2020 17:01:48 +0530 [thread overview]
Message-ID: <20201221113151.94515-4-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20201221113151.94515-1-jagan@amarulasolutions.com>
i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini
from Engicam.
General features:
- NXP i.MX8M Mini
- Up to 2GB LDDR4
- 8/16GB eMMC
- Gigabit Ethernet
- USB 2.0 Host/OTG
- PCIe Gen2 interface
- I2S
- MIPI DSI to LVDS
- rest of i.MX8M Mini features
i.Core MX8M Mini needs to mount on top of Engicam baseboards
for creating complete platform solutions.
Add support for it.

Changes for v2:
- updated commit message
- add cpu nodes
- add fec1 node
- fixed pmic tree comments
- dropped engicam from filename since it aligned with imx6 engicam
dts files naming conventions.
