Subject: [PATCH net-next v4] dt-bindings: net: qcom,ipa: make imem interconnect optional
Date: Wed, 11 Aug 2021 09:18:02 -0500	[thread overview]
Message-ID: <20210811141802.2635424-1-elder@linaro.org> (raw)

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 <elder@linaro.org>

v4: Hopefully I included all the right addressees this time.
v3: Based on net-next/master; sending for inclusion in net-next.
v2: Based on linux-next/master.

An earlier version was sent with some DTS updates and was accepted
into the net-next/master branch, but later reverted.  Bjorn accepted
the re-sent DTS patches into the Qualcomm repository; this patch
should go (by itself) via the net-next repository.
