should be: Enable bytes per clock setting
What is the reason for selecting commands per clock vs bytes per clock?
Also probably mention Bspec: 51762 in the commit message too.
It's a default configuration used to interpret the A36/A37 counters here

I know bit 29 has to be set for DG2. I think the commit message is
wrong. Nice catch, thanks
