Subject: Re: [PATCH] coresight: etm4x: Add ETM PIDs for Cortex-A55 and Cortex-A78

Hi Sai,

This patch does not apply to coresight/next - possibly because the PID
for A55 has been added in an earlier patch ( [b8336ad947e19 ]
coresight: etm4x: add AMBA id for Cortex-A55 and Cortex-A75).

Regards

Mike
