Subject: [PATCH 4/5] arm64: dts: freescale: support Engicam i.Core MX8M Plus FE C.TOUCH 2.0 board
Date: Fri, 30 Oct 2026 17:35:43 +0100 [thread overview]
Message-ID: <20261030163547.2682583-5-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20261030163547.2682583-1-dario.binacchi@amarulasolutions.com>
Support Engicam i.Core MX8M Plus Fast Ethernet C.TOUCH 2.0 board with:
- 10/100 Ethernet
- CAN
- RTC
- USB host, through an on-board hub
- USB OTG, device only
- Micro SD card connector
- LVDS display connector
The C.TOUCH 2.0 carrier board is described in a separate dtsi, so that
it can be shared with the other i.Core MX8M Plus SoMs.
