Subject: [PATCH v2 4/4] ARM: dts: qcom: msm8974: add interconnect nodes
Date: Thu, 24 Oct 2019 06:31:40 -0400
Message-ID: <20191024103140.10077-5-masneyb@onstation.org> (raw)
In-Reply-To: <20191024103140.10077-1-masneyb@onstation.org>

Add interconnect nodes that's needed to support bus scaling.

Signed-off-by: Brian Masney <masneyb@onstation.org>

Changes since v1:
- sort interconnect nodes by address
- correct interconnect path for display:
  MNOC_MAS_MDP_PORT0 -> BIMC_SLV_EBI_CH0
