Merge branch 'lpc32xx/soc' of https://github.com/vzapolskiy/linux into next/cleanup 

From Vladimir Zapolskiy:

"The main change is a switchover to a common clock framework driver for
LPC32xx, this also allows to reuse a shared LPC32xx clockevent driver, and
hence remove legacy clock and timer drivers from arch/arm/mach-lpc32xx.

I'm adding an official LPC32xx maintainer Roland to Cc, however he seems
to be unresponsive for a quite long time (since 2014)."

* 'lpc32xx/soc' of https://github.com/vzapolskiy/linux

:
  arm: lpc32xx: remove direct control of GPIOs from shared mach file
  arm: lpc32xx: remove selected HAVE_IDE
  arm: lpc32xx: switch to common clock framework
