[PATCH 1/1] arm64: dts: rockchip: rk356x: Fix PCIe register and range mappings

Sat Nov 12 03:41:26 PST 2022


The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.
