Hi Florian,

I've done much the same for Boston already - do these patches work for

Or you could fetch & cherry-pick them from the linux-mti.git repository:

git remote add mti git://
git fetch mti
git cherry-pick 75b59b3bddde~7..75b59b3bddde

They apply cleanly to v4.5, hopefully won't need much massaging to apply
to current master. When I get to resubmitting the Boston board support
these patches will be part of it.
