[PATCH 1/6] ARM: nomadik: move MMC/SD card detect GPIO to board DTS

[PATCH 1/6] ARM: nomadik: move MMC/SD card detect GPIO to board DTS

[Linus Walleij]

This pushes the setting of the card detect GPIO pin down into
the top-level file for the board, since it is not a property of
the ASIC (which this DTSI is about) but a property of the board
design.

[PATCH 2/6] ARM: nomadik: disable chrystals in top level board files

[Linus Walleij]

Do not force disable the chrystals in the SoC file, this is
per-board dependent.

[PATCH 3/6] ARM: nomadik: move GPIO I2C to S8815 board file

[Linus Walleij]

The idea to use two GPIO pins for bit-banged I2C is an S8815
pecularity, so move this over to the board-specific file and
out of the SoC core DTSI file.

The SoC file defines the location and type of the ethernet

means necessary to have an ethernet adapter connected to this
memory space.
