Merge tag 'nomadik-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt
Merge "Nomadik updates for the v3.19 series" from Linus Walleij: Nomadik changes for the v3.19 development series: - Rearrange the DTS files to make a pure SoC-specific file and a pure board file for S8815. - Add the device tree for the NDK15 board. - Update the defconfig and configure in the STMPE expander by default on the Nomadik. * tag 'nomadik-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: ARM: nomadik: configure in STMPE support ARM: update Nomadik config ARM: nomadik: device tree for NHK15 board ARM: nomadik: push ethernet down to board ARM: nomadik: set up MCDATDIR2 ARM: nomadik: move GPIO I2C to S8815 board file ARM: nomadik: disable chrystals in top level board files ARM: nomadik: move MMC/SD card detect GPIO to board DTS Signed-off-by: Olof Johansson <olof@lixom.net>
