[PATCH v2 0/3] Add eusb2 repeater squelch detect parameter override

[Krishna Kurapati]

Add support for eusb2 repeater squelch detect parameter override via DT.

Squelch detect parameter adjusts the voltage level for the threshold used
to detect valid high-speed data.

Changes in v2:
- Modified logic to write to squelch related register in driver code
- Added multipleOf property in bindings to reflect values can be multiple
  of 1000.

If thi sis adjustment in ratio, then bp is correct. Some sort of
explanation in commit msg would be nice, but I don't want to stall the
patchset for that.

Assuming this is indeed ratio without actual SI units:

Yes, this register values indicates % change in squelch limit. Hence I 
used basis points instead of uV or mV. Will update commit text accordingly.

Thanks for the RB Krzysztof,

  Can I update the following as commit text and retain your RB when 
sending v3:

"Add squelch detect parameter update for synopsys eusb2 repeater. The
values (indicated in basis-points) depict a percentage change with
respect to the nominal value."

I forgot to ask, do these values apply to all of the supported repeaters?

(SM8{5/6/7}50/ Kaanapali/ Hamoa). For all of them, the above table is same.

This happens to be the only(?) node in this file that has status first
instead of last. May I ask you to fix that up, since it's even visible
in the diff?

Also, does the QRD also need a similar update?
