It's generally the clocking configuration, things with fancy clock trees
don't play so nicely with generic systems where we want to configure
them at runtime, or things with complex routing in the CPU where we
only recently started getting bindings that were functional enough to
use.  Tegra is fairly complex internally.

This is true, but still it's more optimal to use flags in a single
common driver for the minor differences rather than to duplicate 90% of
the code. In practice majority of tegra boards are derived from the same
reference design, thus the h/w configurations are mostly the same.

If you can do it yes, though some of the CODECs can have sufficiently
interesting clocking to make it useful to do something different - not
sure if any of those are upstream though, WM8903 ought to with the right
board I think.
