Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"We've got a fairly large cleanup branch this time. The bulk of this
is removal of non-DT platforms of several flavors:
- Atmel at91 platforms go full-DT, with removal of remaining
board-file based support
- OMAP removes legacy board files for three more platforms
- removal of non-DT mach-msm, newer Qualcomm platforms now live in
mach-qcom
- Freescale i.MX25 also removes non-DT platform support"
Most of the rest of the changes here are fallout from the above, i.e. for
example removal of drivers that now lack platforms, etc.
