Merge branch 'lpc32xx/core2' of git://git.antcom.de/linux-2.6 into next/soc 

From Roland Stigge <stigge@antcom.de>:
this LPC32xx core update (branch lpc32xx/core2) builds upon the
previously provided lpc32xx/core-fixes. Basically including PWM support
(for the PWM driver from Alexandre already in the pwm tree), and
CPU ID.

* 'lpc32xx/core2' of git://git.antcom.de/linux-2.6

:
  ARM: LPC32xx: Add PWM support
  ARM: LPC32xx: Add PWM clock
  ARM: LPC32xx: Set system serial based on cpu unique id
