Have you though about support for lines that are pulled low instead of
high? Those aren't as common, but it is conceivable that some
hardware would need it.
So if the idea is (if I get it correctly) that this thing is an input
sometimes and open drain/collector output sometimes, then
open source/emitter for the inverse situation is an equally valid
case right? In that case I think it'd be best to add both.
The COH901 driver for U300 supports open source/emitter
BTW.
Yes, I can add the open source also but like to be in incremental
change. Not together with open drain.
We can go with:
- open drain core driver support.
- open drain sysfs interface support
- open source core driver support
- open source sysfs interface.
I have already changes for the first 2 which we can review/apply,
Meanwhile I will work on open source support.
Does it look good?
Yours,
Linus Walleij
