Some platforms provides a mechanism for configuring the mapping between
(one or two) DisplayPort intfs and their PHYs.
In particular SC8180X provides this functionality, without a default
configuration, resulting in no connection between its two external
DisplayPort controllers and any PHYs.
I have to cross-check internally about what makes it mandatory to
program this only for sc8180xp. We were not programming this so far
for any chipset and this register is present all the way from sm8150
till xe10100 and all the chipsets do not have a correct default value
which makes me think whether this is required to be programmed.
Will update this thread once I do.
Ok, I checked more. The reason this is mandatory for sc8180xp is the
number of controllers is greater than number of PHYs needing this to be
programmed. On all other chipsets its a 1:1 mapping.
Correction, number of controllers is < number of PHYs.
Thanks, I'll c&p your explanation to the commit message if you don't mind.
Yes you can, pls go ahead.
I am fine with the change once the genmap comment is addressed.
