[PATCH] arm64: dts: qcom: x1e: bus is 40-bits (fix 64GB models)

From: Jonathan Marek

Date: Thu Nov 27 2025 - 16:31:24 EST


Unlike the phone SoCs this was copied from, x1e has a 40-bit physical bus.
The upper address space is used to support more than 32GB of memory.

This fixes issues when DMA buffers are allocated outside the 36-bit range.
