Merge tag 'at91-for-next-soc' of git://github.com/at91linux/linux-at91 into at91/mci
AT91 SoC related code modifications: a cleanup in defconfigs and a one liner in a board file. The most important is the move to atmel-mci driver in AT91 SoC & boards. The old at91_mci (marked as deprecated) will be removed in 3.7. So all platform data for this old driver are erased and replace by information needed by atmel-mci driver. * tag 'at91-for-next-soc' of git://github.com/at91linux/linux-at91: ARM: at91: add atmel-mci support for chips and boards which can use it ARM: at91/defconfig: change the MCI driver to use in defconfigs ARM: at91: set i2c_board_info.type to "ds1339" directly ARM: at91/defconfig: Remove unaffected config option Signed-off-by: Arnd Bergmann <arnd@arndb.de>
