Tree did change quite a bit in a short span of time between me fetching and 
sending, sorry for the trouble.

The base commit is 10f540c09cf9 "ice: default to TIME_REF instead of TXCO on 
E825-C". In case you cannot access it, I have pushed the tree to my github.

This version is probably much closer to what would be in dev-queue eventually, 
compared to a properly rebased one. Some patches were pulled out of dev-queue 
because of validation problems, but should be back pretty soon, as far as I 
know. Those patches are the reason why I have an additional fix in the github 
tree.
