I have a newbie question. How can one read the device tree..? Moreover, lets
say that the autoconf code detects 2 cards for my driver, and passes me the
unit numbers for these cards (say, 0 and 1) in dv_unit. Lets also assume
that my driver interprets a devno from userland as "top 2 bits are the card
How will someone in the userland make devnos for my cards (given that they
cant find the respective unit numbers, unless I provide an ioctl)...?
I apologize if the question sounds confused!
