I've only seen patch #5 of this series, so I couldn't > tell what else was up. Sorry. This set touched a lot of different subsystems. (ARM, spi, rtc, inpu= t, mfd, ..) The To: and Cc: list gave me quite some headache. :) Next time I m= ake sure that at least LKML is cc'ed on the whle series so people have a lace to look at it in one thread. > > Understand.

Yeah, pretty similar. We had to start from 2.4 driver code to get in touch = with this chip. Motorola did not offer any docs. Also the usual embedded board out-of-tree problem. We are doing a lot better now since the last two kerne= ls though. Better workflow, tools, faster reaction on review and more energy towards upstream submissions. regards Stefan Schmidt ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great priz= es Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=3D100&url=3D/
