If I was a guessing man (which I'm not, but if I was), I'd guess that
this is because on rk3288 there was only one DP port and it was an EDP
port. ...but since there was only one people just referred to it as
the "DP" port and that was codified in the bindings. On rk3399 there
are two ports: one EDP and one DP. All of a sudden we need to
differentiate.
Any better suggestions for how to deal with that?
nope - everything as it should be in that regard then - the rk3288-dp is
permanent now anyway.
But it looks like I'm sort of blind blind and only now have seen the
separate DP controller chapter in the TRM (probably because I somehow didn't
expect a second controller).
RK3399 eDP controller have cut off the DP-Audio function and DP-HDCP
function, so it can't be treated as DP interfaces any more, that's why I
call it "eDP".
