Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"Again we have a sizable (but not huge) cleanup branch with a net delta
of about -3k lines.
Main contents here is:
- A bunch of development/cleanup of a few PXA boards
- Removal of bockw platforms on shmobile, since the platform has now
gone completely multiplatform. Whee!
- move of the 32kHz timer on OMAP to a proper timesource
- Misc cleanup of older OMAP material (incl removal of one board
file)
- Switch over to new common PWM lookup support for several platforms
There's also a handful of other cleanups across the tree, but the
above are the major pieces"
