Is that how properties are defined nowadays ? I am left with
no clues how this is supposed to be interpreted by a driver.
What does "08 10 02" mean ? How does that refer to "the number of
active channels per VM" ?

Also, I am not a devicetree expert, but I am quite sure that all
those chip specific properties would need a vendor prefix.
