the ATU address space.
(The old way of getting the configuration address space from "ranges"
is deprecated and should be avoided.)
-- num-lanes: number of lanes to use
RC mode:
- #address-cells: set to <3>
- #size-cells: set to <2>
- clock-names: Must include the following entries:
- "pcie"
- "pcie_bus"
+- snps,enable-cdm-check: This is a boolean property and if present enables
+ automatic checking of CDM (Configuration Dependent Module) registers
+ for data corruption. CDM registers include standard PCIe configuration
+ space registers, Port Logic registers, DMA and iATU (internal Address
+ Translation Unit) registers.
RC mode:
- num-viewport: number of view ports configured in hardware. If a platform
does not specify it, the driver assumes 2.
