Merge tag 'socfpga_fixes_for_3.18' of git://git.rocketboards.org/linux-socfpga-next into fixes
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.
