Andrew and Florian, thanks for your input.

I'm not keen on the sysfs bin file either, the existing driver has this,
and we use it because it's there.

Our use case is as follows: all we need is a reset on boot, followed by
a few static register bitfiddles which reflect the way we've integrated
the IC into our product. There is no further Linux interaction.
I guess the devicetree would be a natural place to store the required
register changes. No need for sysfs.

As I said before, not sure how others use this chip.

Would the above be attainable by a (trivial) DSA driver?
