Roland Stigge a0a30b6a69 ARM: LPC32xx: Remove wrong re-initialization of MMC clock register
This patch fixes a bug, (wrongfully) resetting the value of
LPC32XX_CLKPWR_MS_CTRL back to its initial contents (after careful setup). This
was discovered only with a board/bootloader combination (EA3250) where the
contents of the respective register wasn't already at the correct value on
Linux boot.

Roland Stigge 714daf73d0 ARM: LPC32xx: clock.c: Fix lpc-eth clock reference
During a complex merge for v3.4, one line of the commit
c20b909be9 ("ARM: LPC32xx: Ethernet support") was
reverted wrongly ("lpc-eth.0" -> "lpc-net.0") while the other conflicts were
merged correctly. This patch re-applies the clock name "lpc-eth.0".

Olof Johansson 1f5b7dcfda ARM: Non-critical bug fixes
Simple bug fixes that were not considered important enough for inclusion
 into 3.3. One bug fix was originally intended for 3.3 but accidentally
 got missed, but is not marked stable because it should only get
 backported once later fixes also make it into v3.4.

Merge branch 'fixes-non-critical' into next/drivers2

fixes-non-critical has already been merged upstream, and there are a
handful of annoying context conflicts that it makes sense to resolve
before sending up. Part of this is because there was parallel development
going on between more urgent fixes and general driver fixups, it should
settle down once the lpc32xx platform reaches a more steady state.

Conflicts:
	arch/arm/mach-lpc32xx/clock.c
	arch/arm/mach-lpc32xx/common.h

Roland Stigge 48a5dedfa7 ARM: LPC32xx: USB Support
This patch adds OHCI support to the LPC32xx ARM platform. Besides the trivial
addition of platform "usb-ohci" support, fixes for the USB PLL have been added
to arch/arm/mach-lpc32xx/clock.c, ported from NXP's lpclinux.com.

(This is the mach-lpc32xx specific part, the USB subsystem specific changes are
in a separate patch for the USB maintainers.)

This patch fixes the mutex issue in clock.c, as done in Kevin Wells' original

In some cases, the clock drivers could grab a mutex twice in an improper
context. This patch changes the mutex mechanism to a simple irq lock/unlock
mechanism and removes un-needed locks from some functions.
