Does anyone know what alternate tuning Albert Collins used? I can see on videos he used a capo on the 7th fret but there is conflicting info on his tuning from my googling.

Also the tuning at the end of the above video EGEGBE, would it be know as E triad tuning, Open E minor tuning or something else entirely?
