From: Josua Mayer Date: Fri, 13 Mar 2026 12:30:57 +0000 (+0200) Subject: arm64: dts: freescale: add support for SolidRun i.MX8MP HummingBoard IIoT X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8da7bfdcda753ef4d7890f55966ffdbda785e72e;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: freescale: add support for SolidRun i.MX8MP HummingBoard IIoT Introduce support for the SolidRun i.MX8MP HummingBoard IIoT platform. This board is a new design based on the i.MX8MP System on Module and does not share much hardware with previous HummingBoard variants. It comes with some common features: - 3x USB-3.0 Type A connector - 2x 1Gbps RJ45 Ethernet - USB Type-C Console Port - microSD connector - RTC with backup battery - RGB Status LED - 1x M.2 M-Key connector with PCI-E Gen. 3 x1 - 1x M.2 B-Key connector with USB-2.0/3.0 + SIM card holder - 1x LVDS Display Connector - 1x DSI Display Connector - GPIO header - 2x RS232/RS485 ports (configurable) - 2x CAN In addition there is a board-to-board expansion connector to support custom daughter boards with access to SPI, a range of GPIOs and - notably - CAN and UART. Both 2x CAN and 2x UART can be muxed either to this b2b connector, or a terminal block connector on the base board. The routing choice for UART and CAN is expressed through gpio mux-controllers in DT and can be changed by applying dtb overlays.
