This data structure really reflects what the datasheet says. Typically,
for SoCs where each pin is independently muxable (AT91, i.MX23/28,
Marvell, and probably many more), the datasheet has a big array, with
one line per pin, and then several columns which tell for a given pin,
what is "function 0", "function 1", "function 2", "function 3", etc.

This is a valid reason to keep it as is in my book.
Readability along with a datasheet is important, most important
is that it has a good structure for those maintaining the driver.

Is this datasheet available so I can get the picture?
