Subject: Re: [PATCHv9 2/3] arm64: dts: qcom: msm8998: Add Coresight support
Sai,
This patch breaks boot on the 835 laptops. However, I haven't seen
the same issue on the MTP. I wonder, is coresight expected to work
with production fused devices? I wonder if thats the difference
between the laptop and MTP that is causing the issue.
Let me know what I can do to help debug.
