Hi dee Ho Krzysztof,

Thanks for the review! It's nice you had the time to take a look on RFC :)

Out of the curiosity - why is that? (Please, don't take me wrong, I am
not trying to argue against this - just learn the reason behind). I
can't immediately see the harm caused by adding new properties later
when we learn more of hardware. (and no, I don't expect this simple IC
to gain at least many properties).

Oh, yes. So it seems.

Strange, I could have sworn I used hyphen in binding file names
previously although the comma has been used in the compatible. I had to
go back in time (lore,kernel.org) to check my earlier submissions. Well,
my mind seems to be playing tricks on me @_@. I'll fix this before
sending out non RFC series :)

Good catch (as always)! Thanks!
