That's great news!

As far as we (TUB) are concerned, we can merge the experimental branch with
the main development branch immediately. However, I did not receive any
comments about the effects of the changes on other msp430 platforms apart
from eyesIFX. For example, with the new changes, reconfiguration is
happening after every request/release cycle, leading to reconfiguration of
the SPI for each packet on telos for example. If there are no objections, we
only need to move from passing the config by value into passing by pointer
(to unify with the way it is done for the ADCs and to save a bit on the
overhead) and merge. The TDA5250 is fully updated to work with the usart
changes as well as with the new resource arbitration code from Kevin.
