Doesn't the regulator need to be "bound" to a device for the driver to use the proper name for the regulator? I mean, in this case the dvi driver wants to get a regulator named "vdd_5v" (or something like that, I'm not sure what's the proper name). The USB host driver uses a name "vcc", while the real name of the regulator is "hsusbX_vcc". If DVI driver wanted to use the regulator, it'd need to get "hsusbX_vcc". Which, I presume, would work, but is board specific and hacky, and it makes handling EPROBE_DEFER a bit more difficult. Then again, maybe that's still simpler than making the regulator always-on, as there are complications with that approach also, which we are currently studying. >>> So I think the simplest solution is to make DC_HST_5V always-on.

I'll have a look, maybe there's something I'm missing. Tomi
