The series add support for ltc2305 controller from
Linear Technology Corporation(lltc).
This is low noise, low power, 2 channels 12-bit successive
approximation ADCs.

With this version I also noticed a clash, but I forgot to reply yesterday... TBH, I prefer the approach in the other series. But this can also do it by splitting the chip_info introduction to the separate change. Anyway, if it's applied, in the case of _this_ work it's not a big deal as the result looks sane. > To hussle things along a touch I skipped the normal pushing > it out as testing first (what could possibly go wrong ;) -- With Best Regards, Andy Shevchenko
