Subject: [PATCH v3 1/6] dt-bindings: interconnect: Add generic qcom bindings
Date: Fri, 31 Jul 2020 20:32:10 -0700	[thread overview]
Message-ID: <20200801033215.1440-2-mdtipton@codeaurora.org> (raw)
In-Reply-To: <20200801033215.1440-1-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().
