Merge tag 'fixes-v3.18-not-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical

Merge "non-urgent omap fixes for v3.18 merge window" from Tony Lindgren:

Fixes for omaps that were not considered urgent enough
for the -rc cycle:

- Fixes for .dts files to differentiate panda and beaglebone versions
- Powerdomain fixes from Nishant Menon mostly for newer omaps
- Fixes for __initconst and of_device_ids const usage

* tag 'fixes-v3.18-not-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: make of_device_ids const
  ARM: omap2: make arrays containing machine compatible strings const
  ARM: OMAP4+: PM: Use only valid low power state for CPU hotplug
  ARM: OMAP4+: PM: use only valid low power state for suspend
  ARM: OMAP4+: PM: Make logic state programmable
  ARM: OMAP2+: powerdomain: introduce logic for finding valid power domain
  ARM: OMAP2+: powerdomain: pwrdm_for_each_clkdm iterate only valid clkdms
  ARM: OMAP5: powerdomain data: fix powerdomain powerstate
  ARM: OMAP: DRA7: powerdomain data: fix powerdomain powerstate
  ARM: dts: am335x-bone*: Fix model name and update compatibility information
  ARM: dts: omap4-panda: Fix model and SoC family details
  + Linux 3.17-rc3
