Merge tag 'imx-cleanup-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/cleanup
Merge "ARM: imx: cleanup for 3.18" from Shawn Guo:
The i.MX cleanup for 3.18:
- Reomve a few i.MX27 and i.MX1 board files
- Remove imx_scu_standby_enable() since core code handles scu
standby now
- Remove unnecessary iomux declaration
- Remove useless sound card property from vf610-twr dts
* tag 'imx-cleanup-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
ARM: imx: Remove mach-mxt_td60 board file
ARM: i.MX: Remove i.MX1 ADS board support
ARM: dts: vf610-twr: remove useless property for sound card.
ARM: imx: remove imx_scu_standby_enable()
ARM: i.MX: Remove Phytec i.MX27 PCM038/PCM970 board files
ARM: i.MX: Remove mach-cpuimx27sd board file
ARM: imx: iomux: Do not export symbol without public declaration
