My gut feeling is that the IS_MOBILE check could also be dropped. Not
quite sure though since VLV_D is not mentioned anywhere in the docs
AFAICS.

Anyway dropping the 830 check definitely makes sense so:

I think in the old gens we've pretty much just used IS_MOBILE as HAS_LVDS.
vlv/chv having edp panels instead makes that a bit more complicated, but
generally I think a new IS_MOBILE check is bogus.

Ping: Status of the i830 code?

[Thomas Richter]

Hi Ville, hi Daniel,

this is again a "ping" on the status of the i830 code. I reviewed the 
code I received, at least the code I could review (I do not know enough 
about the internal wirings of the intel_display source, only on the 
ns2501 dvo source), but I haven't heart anything back. Is there anything 
I can do to help to move Ville's modifications for i380 into the kernel?

Thanks,
     Thomas

Me getting back to working internet essentially so that I can give them a
spin on my own i830m.
