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. Signed-off-by: Alex Elder <redacted> --- v3: Based on net-next/master; sending for inclusion there. v2: Based on linux-next/master, to be taken via Qualcomm repository. I sent version 2 of this only to linux-arm-msm, but Bjorn reminded me this binding update ought to go through the net-next repository. -Alex .../devicetree/bindings/net/qcom,ipa.yaml | 24 ++++++++++++------- 1 file changed, 16 insertions(+), 8 deletions(-)
