[PATCH] arm64: dts: msm8916: fix Coresight ETF graph connections

From: robh@kernel.org (Rob Herring)
Date: 2018-05-08 15:09:51
Also in: linux-arm-msm, linux-devicetree
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

The ETF input should be connected to the funnel output, and the ETF
output should be connected to the replicator input. The labels are wrong
and these got swapped:

Warning (graph_endpoint): /soc/funnel at 821000/ports/port at 8/endpoint: graph connection to node '/soc/etf at 825000/ports/port at 1/endpoint' is not bidirectional
Warning (graph_endpoint): /soc/replicator at 824000/ports/port at 2/endpoint: graph connection to node '/soc/etf at 825000/ports/port at 0/endpoint' is not bidirectional

Fixes: 7c10da373698 ("arm64: dts: qcom: Add msm8916 CoreSight components")
