Hi Krzysztof,

TL;DR: Serial patches from this series don't really depend on USI
driver and can go via Greg's tree.

I'd say ideally those should be applied right after USI driver
patches. Because otherwise we'd have double initialization of USI
block (from USI driver and from serial driver), which wasn't tested
and may lead to not functional USI (though I think it should be fine).
That's why I decided to keep those in one single patch series. But if
we don't care about some short period of not tested behavior -- then
those can go via Greg's tree.
