Pull ARM SoC fixes from Kevin Hilman:
 - MSM: GPIO fixes (includes old code removal)
 - OMAP: earlyprintk regression, AM33xx cpgmac PM regression
 - OMAP5: urgent fix for potentially harmful voltage regulator values
 - Renesas: gpio-keys fix, fix SD card detection, fix shdma calculation
   error
 - STi: critical SMP boot fix
 - tegra: DTS fix for usb-phy
 - a couple MAINTAINERS updates

(Arnd is on paternity leave, Kevin is stepping up to help arm-soc
maintenance)
