I was expecting you'd ask some clarification questions about the RCW
override procedure that I've informally described over email, so I guess
you haven't spent any more time on this.

I'm letting you know that very soon, I will have to start my work on
porting the backplane driver posted here:
to the Lynx 10G SoCs. And for that, I need a SerDes driver as a base :)

I was wondering how inclined are you to respond positively to the
feedback that the lynx-10g driver should have a look and feel as close
as possible to lynx-28g, given that they're very similar.

Because internally within NXP, we do have a version of the lynx-10g
driver which is contemporary with lynx-28g from mainline, but we didn't
publish it because protocol changes didn't work (for the same reason
that they don't work with your driver). With that driver, you can think
of the feedback about the similar look and feel as being "implicitly applied"
(being written by the same author), so I'm starting to consider more and
more seriously the option of basing my work on that instead of your v14
(on which I'd need to spend extra time to modify the dt-bindings with PCCRs,
concept of lane groups, concept of PLL CCF driver, etc).

What are your thoughts?
