[PATCH 2/2] arm64: dts: freescale: add MR-NAVQ95 basic board support

From: Laurentiu Mihalcea

Date: Tue Aug 25 2026 - 08:12:52 EST

From: Laurentiu Mihalcea <laurentiu.mihalcea@xxxxxxx>

Add basic support for NXP's MR-NAVQ95 board. This board is designed for
robotics applications (e.g. drones, rovers, humanoids, etc..) and has the
following hardware feats (list is not exhaustive):

* based on i.MX95 19x19 SoC
* 64GB eMMC
* up to 16GB of LPDDR5 memory
* 1 x USB 2.0 TypeC
* 1 x USB 3.0 TypeC
* 1 x RJ45 port with RTL8211 PHY

The support targets revision B of the board.
