Can this be made into another struct, like msm_dp_desc, that also
indicates what type of DP connector it is, i.e. eDP vs DP? That would
help me understand in modetest and /sys/class/drm what sort of connector
is probing. dp_drm_connector_init() would need to pass the type of
connector appropriately. Right now, eDP connectors still show up as DP
instead of eDP in sysfs.


I like it, will spin a v3 with this.

Hi Bjorn,

Have you spin off V3 yet?
When you expect your patches related to DP be up streamed?

Thanks,
