From b769cf44ed55f4b277b89cf53df6092f0c9082d0 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 11 Aug 2021 09:18:02 -0500 Subject: [PATCH] dt-bindings: net: qcom,ipa: make imem interconnect optional On some newer SoCs, the interconnect between IPA and SoC internal memory (imem) is not used. Update the binding to indicate that having just the memory and config interconnects is another allowed configuration.
