[alsa-devel] [PATCH 0/9] Update FLL calculations on Arizona devices

Newer versions of the Arizona IP have several differences
in the FLL configuration. The reference and synchroniser
paths have slightly difference FRATIO encodings and the
expanded encoding on the reference path should be used to
avoid integer mode operation.

This series of patches does some refactoring on the FLL
configuration code, previously calculation of the FLL
configuration was done before we knew whether this would be
applied to reference or synchroniser path. These patches
add some checks to make sure the requested clock can be
accomodated and then does the calculations once we knew
where they will be applied. Additionally, we add support for
the encodings on the newer IP.
