[PATCH v2 3/4] arm64: dts: sdm845: Set the virtual address range for GMU allocations

From: Jordan Crouse <hidden>
Date: 2020-02-20 18:27:09
Also in: linux-arm-msm, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

GMU DMA allocations need to be mapped between 0x60000000 and 0x80000000 in
the GMU virtual address space. Specify the dma-range so the iova allocator
does the right thing.
