Linus Torvalds a5e1d715a8 ARM: SoC cleanups for v4.4
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.

help
This option enables support for event stream generation based on
the ARM architected timer. It is used for waking up CPUs executing
the wfe instruction at a frequency represented as a power-of-2
divisor of the clock rate.
The main use of the event stream is wfe-based timeouts of userspace
locking implementations. It might also be useful for imposing timeout
on wfe to safeguard against any programming errors in case an expected
event is not generated.
This must be disabled for hardware validation purposes to detect any
hardware anomalies of missing events.
