SubjectRE: [PATCH] drm: adding SDI to drm_connector_enum_list
Date
Hi Daniel,

Thanks for your reply.
Currently I am using connector type 'Unknown' , and functionally it serves my need.
Intention for sending this patch is that userspace tools should recognize SDI drivers as SDI only.
Also, I see there are number of 'SDI' drivers getting developed 'under the hood' in linux kernel.
This patch will benefit all of them.

It will be great if you could consider it.

Regards,
Saurabh

This is an uapi change, i.e. userspace needs to be updated. Do you _really_ need this? I'd recommend to just use something existing (go with VIRTUAL maybe, not sure).

Either way, needs to come together with the actual users and userspace side patches. If you really want this.
