Thank you for making modifications to this patch - I am happy with how it stands
now.  I tried to compile it on my side on a 5.0-rc3 kernel and even after
applying the above two patches you pointed out I get the following error:

Error: /home/mpoirier/work/coresight/kernel-maint/arch/arm64/boot/dts/qcom/sdm845.dtsi:1356.31-32 syntax error
FATAL ERROR: Unable to parse input tree

>From what I see neither aoss_qmp or AOSS_QMP_QDSS_CLK are defined.  Are there
more patches that need to be applied?

Thanks,
Mathieu
