Nord relocates several DP PHY and QSERDES v8 COM registers relative
to existing SoCs.
Why?
Add Nord-specific defines for the relocated and
new-only registers in phy-qcom-qmp-qserdes-dp-com-v8.h and
phy-qcom-edp.c so Nord sequences can reference them by name.
Typically we don't do it, If something differs, it should get its own
set of headers, describing all necessary offsets (especially for the
QSERDES). Otherwise it's not obvious if other regs (without the _NORD
counterpart) are valid or not.
Ack,
Are you suggesting that we introduce a new header file for QSERDES?
If so, we're currently using the v8 header. What naming convention
should we follow for the new header file?

I'd suggest adding these together with the actual users.
Ack, I will update in the next revision.
Thanks,
