Subject: [PATCH 1/2] dt-bindings: interconnect: Add generic qcom bindings
Date: Mon, 22 Jun 2020 21:05:14 -0700 [thread overview]
Message-ID: <20200623040515.23317-2-mdtipton@codeaurora.org> (raw)
In-Reply-To: <20200623040515.23317-1-mdtipton@codeaurora.org>
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().
