Merge tag 'imx-dt64-7.2-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/frank.li/linux into soc/dt
i.MX arm64 device tree changes for v7.2 (part2)
- Revert the 32-bit non-prefetchable PCIe window from 3 GiB back to 1 GiB
to prevent overlap between inbound DMA address space and low system RAM.
Such overlap can cause DMA transactions to be routed to a BAR on the same
host bridge instead of system memory.

arm64: dts: lx2160a-rev2: avoid 32-bit pcie window system ram overlap
