Subject[PATCH v5 4/4] dt-bindings: PCI: cadence: Deprecate inbound/outbound specific bindings
Date
Deprecate cdns,max-outbound-regions and cdns,no-bar-match-nbits for
host mode as both these could be derived from "ranges" and "dma-ranges"
property. "cdns,max-outbound-regions" property would still be required
for EP mode.

Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
---
Changes from v4:
Keep "cdns,max-outbound-regions" mandatory property for EP mode while
deprecating it for host mode
