Add a new device tree parameter, "arm,max-burst-size" to configure
the max burst size that can be initiated by TMC-ETR on the AXI bus.

Also add description of this property in coresight documentation.

This patch series applies on top of the coresight next branch [1].

Hi

Looks good from a driver  / hw perspective.
As long as the device tree people are happy with the binding then this
set seems OK to me.

Regards

Mike

I have applied this set - it will show up in the coresight-next branch on Monday
once 5.15-rc1 has been released.

Thanks,
Mathieu
