Pull ARM SoC fixes from Olof Johansson:
"Another week, another small batch of fixes.
Most of these make zynq, socfpga and sunxi platforms work a bit
better:
- due to new requirements for regulators, DWMMC on socfpga broke past
v3.17
- SMP spinup fix for socfpga
- a few DT fixes for zynq
- another option (FIXED_REGULATOR) for sunxi is needed that used to
be selected by other options but no longer is.
- a couple of small DT fixes for at91
- ...and a couple for i.MX"

Commit 78b81f4666fb ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:
- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command
In many times the audio card cannot be probed, which causes playback to fail.
After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.
This reverts commit 78b81f4666fbb22a20b1e63e5baf197ad2e90e88.

Fix a typo error, the "emi" names refer to the eim clocks. The change fixes typo in EIM and EIM_SLOW pre-output dividers and selectors clock names. Notably EIM_SLOW clock itself is named correctly.

Merge "SOCFPGA fixes for 3.18" from Dinh Nguyen: These patches fixes an SMP and SDMMC driver hang during boot up on the SOCFPGA platform. Patch "arm: socfpga: fix fetching cpu1start_addr for SMP" fixes the SMP trampoline code in order for CPU1 to correctly fetch it's cpu1start_addr. Patch "ARM: dts: socfpga: rename gpio nodes" renames that GPIO node in order to allow a standard way of specifying status="okay" in the board DTS file. Patch "ARM: dts: socfpga: Fix SD card detect" fixes a SDMMC driver hang during boot. The reason for the hang was the deferred probe of the SDMMC driver was waiting for the GPIO resource that would never come. Patch "ARM: dts: socfpga: Add a 3.3V fixed regulator node" adds a fixed regulator node for the SDMMC driver to use. * tag 'socfpga_fixes_for_3.18' of git://git.rocketboards.org/linux-socfpga-next: ARM: dts: socfpga: Add a 3.3V fixed regulator node ARM: dts: socfpga: Fix SD card detect ARM: dts: socfpga: rename gpio nodes arm: socfpga: fix fetching cpu1start_addr for SMP Signed-off-by: Olof Johansson <olof@lixom.net>

Without the 3.3V regulator node, the SDMMC driver will give these warnings:
dw_mmc ff704000.dwmmc0: No vmmc regulator found
dw_mmc ff704000.dwmmc0: No vqmmc regulator found
This patch adds the regulator node, and points the SD/MMC to the regulator.

v3: Rename nodes to have schematic-name_regulator and remove "boot-on" and
"always-on"
v2: Move the regulator nodes to their respective board dts file and
correctly rename them to match the schematic
