I am sorry that the situation can be stressful.

This is not Rob's fault, at least it's also mine.

The real problem we have is lack of hardware people
reviewing hardware descriptions, to put it simple.
As reviewers we get a bit confused, then we try to make
a mind map of the hardware as most driver developers do,
but as we are not chip designers we will make
mistakes and get confused and there will be a bit
of back-and-forth and inconsistencies.

The bindings have very high ambitions (to describe all
hardware) but it's a bit like food: the less you know
about how it's produced, the better the taste.
In fact it is a best effort and involves a bit of guesswork
and group effort and you are part of the group effort
now :)

Yours,
Linus Walleij
