[PATCH v1 2/3] arm64: dts: freescale: Add support for Variscite VAR-SOM-MX8 QuadMax

From: Stefano Radaelli <hidden>
Date: 2026-06-30 09:47:05
Also in: imx, linux-devicetree, lkml
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds 

From: Stefano Radaelli <redacted>

Add device tree support for the Variscite VAR-SOM-MX8 QuadMax
system on module.
This SOM is designed to be used with various carrier boards.

The module includes:
- NXP i.MX8 QuadMax MPU processor
- Up to 8GB of LPDDR4 memory
- Up to 128GB of eMMC storage memory
- Integrated 10/100/1000 Mbps Ethernet Transceiver
- Codec audio WM8904
- WIFI6 dual-band 802.11ax/ac/a/b/g/n with optional 802.15.4 and Bluetooth

Only SOM-specific peripherals are enabled by default. Carrier board
specific interfaces are left disabled to be enabled in the respective
carrier board device trees.
