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
