Merge tag 'integrator-for-v3.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/soc

From Linus Walleij:
Integrator patches for the v3.13 kernel cycle:
- Fix up the LED support
- Update the Integrator defconfig
- Remove ATAG boot path
- Move some stuff over to the device tree

* tag 'integrator-for-v3.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator:
  ARM: integrator: core module registers from compatible strings
  ARM: integrator: use devm_ioremap() to remap CM
  cpufreq: probe the Integrator cpufreq driver from DT
  ARM: integrator: move CM base into device tree
  ARM: integrator: decommission the <mach/irqs.h> header
  ARM: integrator: delete non-devicetree boot path
  ARM: integrator: print the Linux IRQ in LL_DEBUG code
  ARM: integrator: get the LM interrupts from DT
  ARM: integrator: update defconfig
  ARM: integrator: get the CM control register by proxy
