Subject: [PATCH] arm64: dts: qcom: x1e: bus is 40-bits (fix 64GB models)
Date: Thu, 27 Nov 2025 16:29:42 -0500 [thread overview]
Message-ID: <20251127212943.24480-1-jonathan@marek.ca> (raw)
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.
Fixes: af16b00578a7 ("arm64: dts: qcom: Add base X1E80100 dtsi and the QCP dts")
Signed-off-by: Jonathan Marek <jonathan@marek.ca>
