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
