Ok I will drop this from v4 then.

I agree with your point in a more general case (e.g. seperate
audio codec chip connected via SPI), but the reality of the situation for
STi arch is that this device is found in STiH407 family silicon, of which
the two supported upstream devices (STiH407/410) are almost identical SoC's.
Given the recent announcement of "no new SoC's" for STB market, there is unlikely
to be support upstream for new variants and as there is no community board
available new board variants upstream are also unlikely (so far only
ST reference boards are supported upstreamed).
So although I would only consider copying an example as the starting
point for getting something working (and indeed it was the case here). On STi
arch there *should* be a very high probability that copying the exanple
is all that will be required.
Peter.
