The DRM ports are called "DP-1" and "DP-2" so it seems we should match
that.
This is the most common naming for the USB-C DP/HDMI jack events.
It looks like some Intel machines use names like "HDMI/DP, pcm=%d Jack"
(with a pcm device number), but we also have "DP Jack". Not sure which
are are used with USB-C, though. (Or if the former actually support HDMI
altmode.)
I checked this on my machine which has usb-c and I can confirm using HDMI/DP
naming for these jack.
Either way I don't mind having any names, but my point here is to be more
consistent across.
I fear it is till not consistent. On the Intel laptop I see following
jacks:
numid=18,iface=CARD,name='HDMI/DP,pcm=3 Jack'
numid=24,iface=CARD,name='HDMI/DP,pcm=7 Jack'
numid=30,iface=CARD,name='HDMI/DP,pcm=8 Jack'
On the other hand Mediatek and RockChip use just 'DP Jack'.
I'd suggest settling on the latter option. We are closer to MTK and
RockChip rather than Intel.
that is fine with me.
BTW: a platform can easily have 4 (x1e8100) or even 8 (sc8280xp) DP
outputs. Could you please point out why there are just 3 jacks?
The CRD platform that I have access to has 3 ports which is why I
started with 3 ports, but we can add more ports as and when we can
really test them.
