Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups on various subarchitectures from Olof Johansson:
 "Cleanup patches for various ARM platforms and some of their associated
  drivers.  There's also a branch in here that enables Freescale i.MX to
  be part of the multiplatform support -- the first "big" SoC that is
  moved over (more multiplatform work comes in a separate branch later
  during the merge window)."

Conflicts fixed as per Olof, including a silent semantic one in
arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to
omap3xxx_restart(), and a new user of the old name was added).

-	 * As per Errata i520, in some cases, user will not be able to

-	 * This situation occurs while the warm-reset happens during a read
-	 * access to DDR memory. In that particular condition, DDR memory
-	 * does not respond to a corrupted read command due to the warm
-	 * reset occurrence but SDRC is waiting for read completion.
-	 * SDRC is not sensitive to the warm reset, but the interconnect is
-	 * reset on the fly, thus causing a misalignment between SDRC logic,
-	 * interconnect logic and DDR memory state.
-	 * WORKAROUND:
-	 * Steps to perform before a Warm reset is trigged:
-	 * 1. enable self-refresh on idle request
-	 * 2. put SDRC in idle
-	 * 3. wait until SDRC goes to idle
-	 * 4. generate SW reset (Global SW reset)
-	 *
-	 * Steps to be performed after warm reset occurs (in bootloader):
-	 * if HW warm reset is the source, apply below steps before any
-	 * accesses to SDRAM:
-	 * 1. Reset SMS and SDRC and wait till reset is complete
-	 * 2. Re-initialize SMS, SDRC and memory
-	 *
-	 * NOTE: Above work around is required only if arch reset is implemented
-	 * using Global SW reset(GLOBAL_SW_RST). DPLL3 reset does not need
-	 * the WA since it resets SDRC as well as part of cold reset.
