The right thing to do would be a change per patch explaining the reason.
For example, fixing typos in QSERDES_RX_SIGDET_CNTRL, then another to
update tuning values based on hw recommendations. Clocks and reset
should be different patch

This helps us review each change for what it does and helps you down the
line to figure why a line of code was changed
