From 2c510f5bee760a83b1ce0790dcccb8301dd41ce8 Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Tue, 12 Jul 2022 09:59:25 +0800 Subject: [PATCH] dt-bindings: interconnect: Update property for icc-rpm path tag To support path tag in icc-rpm driver, the "#interconnect-cells" property is updated as enumerate values: 1 or 2. Setting to 1 means it is compatible with old DT binding that interconnect path only contains node id; if set to 2 for "#interconnect-cells" property, then the second specifier is used as a tag (e.g. vote for which buckets).
