Understood. Thanks for the clarification. Jeff LaBundy explained it a
bit too. I have addressed all the other comments in this patch series in
my WIP v2. However, I am having quite the trouble casting the buffer to
a struct. The register layout is bit weird. It would have been easier if
they are sets of 8bits or 16bits values. Instead it seems to be split in
terms 4bits and 12bits or I don't know. I am a bit new to this and
having trouble handling endianess with these weird splits in the buffer.
Here is a hand drawn image of the buffer layout [1]. Let me know if you
or anyone have any thoughts on this. Wonder if it's worth the trouble :)

I am gonna try it a few more days and if I can't make it work in a
sensible way, I will probably go with the existing approach.
