You're right. But that's the point: These modules are used on a lot of
different boards, but every board has its own (almost identical)
implementation of the module specific code. This code shall be factored
out to have only a single implementation for each type of NIM in the
kernel source tree.
Other boards, which don't use NIMs, need custom settings anyway. There
is no need and no gain to factor out their PLL setting code or special
register settings. Their code just stays inside the adapter driver,
because it won't be reused for other boards.
