So keeping at91-mci only for old chips is no more necessary. If there are no issues with this new atmel-mci driver, at91-mci driver will be removed for 3.7 release.

Ludovic and Chris, Sure, I will take 1/2 patch of this series through arm-soc. Unfortunately, it seems to be a bit late for 3.5... Anyway, I will talk with Arnd and Olof about the possibility to include it in a "late" or "staging" branch: that will allow this platform data addition to have some exposure in linux-next. We can also imagine that having a better support for atmel-mci driver in AT91 boards will help people gain a more stable system and avoid using a now "deprecated" driver that will be removed in 3.7. So I am personally in favor for an inclusion as soon as possible... Thanks, best regards, -- Nicolas Ferre ^ permalink raw reply [flat|nested] 14+ messages in thread
