The behavior of the MMP platform code depends on whether the
CPU_PXA168/CPU_PXA910/CPU_MMP2 symbols are enabled or not.
I believe the intention here was that these can be left disabled for
a pure DT-only build, but it's not clear if that actually works. At
the minimum, the cpu_is_pxa168() and cpu_is_pxa910() checks behave
differently, which causes changes in the power management code.
For the moment, make the behavior depend on whether CONFIG_ATAGS is set
or not, to make it easier to bisect the removal of the old code later.

As a result, revert the previous fix, and rearrange the code that

simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.

After commit b5aaaa666a85 ("ARM: pxa: add Kconfig dependencies for

As a side-effect of this, the PXA310 and PXA320 support is not built

long as the symbols are enabled. As Robert points out, there are dts

treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following
commands:
