2022-04-08dt-bindings: pci: layerscape-pci: define AER/PME interruptsLi Yang1-26/+32
Different platforms using this controller are using different numbers of interrupt lines and the routing of events to these interrupt lines are different too. So instead of trying to define names for these interrupt lines, we define the more specific AER/PME events that are routed to these interrupt lines. For platforms which only has a single interrupt line for miscellaneous controller events, we can keep using the original "intr" name for backward compatibility. Also change the example from ls1021a to ls1088a for better representation.

2018-12-10dt-bindings: pci: layerscape-pci: removed compatible string "snps,dw-pcie"Hou Zhiqiang1-3/+3
Removed the compatible string "snps,dw-pcie", it is for the reference platform driver for PCI RC IP Protoyping Kits based on the ARC SDP, so it is not suitable for all platform with designware PCIe controller, and platform vendors have themselves' drivers. The compatible string "snsp,dw-pcie" was added by mistake and it's not matched that time, but it is matched because PCIe drivers has been collected recently.

2016-06-16bindings: PCI: layerscape: Add 'dma-coherent' propertyLiu Gang1-0/+4
Add 'dma-coherent' description for PCI nodes. The 'dma-coherent' indicates that the hardware IP block can ensure the coherency of the data transferred from/to the IP block. This can avoid the software cache flush/invalid actions, and improve the performance significantly. The PCI IP block of ls1043a has this capability, so adding this feature to improve the PCI performance.
