Subject: [PATCH 1/2] dt-bindings: interconnect: Add generic qcom bindings
Date:   Mon, 22 Jun 2020 21:05:14 -0700

Precedence: bulk

Add generic qcom interconnect bindings that are common across platforms. In
particular, these include QCOM_ICC_TAG_* macros that clients can use when
calling icc_set_tag().
