[PATCH v2 0/3] arm64: dts: imx9x: Fix PCIe memory window overlap with System RAM
From: hongxing . zhu

This patch series fix PCIe non-prefetchable memory window overlap with
system DRAM on i.MX9 series SoCs (imx95, imx94, and imx943).
The current address 0xe0000000 conflicts with DRAM regions. Sashiko
reports the potential issue in previous review:
The fix relocates the PCI bus address to 0x10000000, a reserved and safe
range. The other PCI bus address and window size remain unchanged.
Changes in v2:
Clarified that the adddress being corrected is the PCI bus address in
the commits.
