This reverts commit 904464b91eca8c665acea033489225af02eeb75a.
The problem pointed out by commit 904464b91eca ("ARM: 7655/1:
smp_twd: make twd_local_timer_of_register() no-op for nosmp")
doesn't exist anymore.
We can safely boot with nosmp and the warning won't show up.

Hi,
with these patches AM437x devices can use TWD/global timers.
At least TWD is now used as sched_clock() which gives better latency as seen
below. Keep in mind that while I ran cyclictest to have a feel for avg latency
this test was not against an RT kernel, so results should be taken with a

AM437x-based boards, can use omap4_local_timer_init()
just fine. Let's use that instead.

AM437x devices sport SCU, TWD and Global timers,
let's add them to DTS so they have a chance to
probe and be used by Linux.

all users of omap4_local_timer_init() are already
DT-only, so we can remove the check for having
DTB or not.
While at that, fix a typo in comment.

Make sure to tell the kernel that AM437x has
TWD and global timers.

The patch adds rtc hwmod. This is present on gp and sk evm and not on
epos evm. Hence adding it selectively using a seprate list.

Enables rtc. RTC can be used to wake up system from suspend
when used with external clock source.

The SoCs on am43x-epos-evm are named am438x.
Hence add the compatiblity string and remove the am4372 string.

The series brings multiple fixes needed to get rtc ticking
on am437x-gp-evm.
This is tested on top of omap-for-v4.3/dt-v2 branch. Boot tested on
AM437X-GP-EVM also tested rtc ticking via sysfs nodes.
The series is on top of this patch:
http://comments.gmane.org/gmane.linux.drivers.devicetree/131
EPOS evms are fitted with a separate family of am43xx SoCs and are named
am438x series. Adding a separate soc_is function to identify that
particular series of SoCs. This can be done to avoid unnecessarily
registering hwmods like rtc when not needed on EPOS evms.

Switch to external clock source during suspend and switch back
to internal source on resume. This helps rtc ticking across suspend.
