Please make your author and S-o-b emails match.
This is an alias and both email will work. Anyway I agree

Hi Boris,
Given the current state of the subsystem I think it might worth start to
think how to expose the devices under /dev.
Thanks for
what a low-level interface to the device looks like
in the kernel? Can this be abstracted as simply pread()/pwrite() plus
an interrupt mechanism, or do we need a set of ioctl() operations as
well?
Like in i2c is likely to need the ioctl() too.

ffort on designing it without a user in
sight.
I kind of agree with that. Vitor, do you have a use case in mind for
such userspace drivers? I don't think it's worth designing an API for
something we don't need (yet).
My use case is a tool for tests, lets say like the i2c to

Hi Boris,
We are very interested in your I3C subsystem proposal and we would like
to colaborate with you in order to add support for the Synopsys Host
Controller.
We are doing the review for this patch-set and will send our conclusions
as soon as possible.
