[PATCH v2 2/2] arm64: dts: qcom: sm8250: Add Coresight support

Sun Sep 26 19:43:01 PDT 2021


Add the basic coresight components found on Qualcomm SM8250 Soc. The
basic coresight components include ETF, ETMs,STM and the related
funnels.
ETM verification and use of Coresight components need Coresight
support in this device tree. Since the ETR sink needs SMMU support,
and SMMU has not been enabled on RB5. ETR is not added to this patch,
and it will be added once SMMU is enabled on RB5. ETF sink has been
added to the device tree for RB5.
