The following commit: 38698be:
OMAP2+: clockevent: set up GPTIMER clockevent hwmod right before timer init

Fixed properly the issue with early init for the timer1

So reverts commit 3b03b58dab that is now

4621d5f8cb OMAP: adapt hsmmc to hwmod framework
OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.

Changes involves:
1) Remove controller reset in devices.c which is taken care of
   by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
   hwmod data file for base address, dma channel number, Irq_number,
   device attribute.
3) Update the driver to use dev_attr to find whether controller
   supports dual volt cards

e08016d0f4 omap: mmc: split out init for 2420
The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.

Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings
for OMAP2420.

38698bef54 OMAP2+: clockevent: set up GPTIMER clockevent hwmod right before timer init
Set up the GPTIMER hwmod used for the clockevent source immediately
before it is used.  This avoids the need to set up all of the hwmods
until the boot process is further along.  (In general, we want to defer
as much as possible until late in the boot process.)

This second version fixes a bug pointed out by Santosh Shilimkar
<santosh.shilimkar@ti.com>, that would cause the kernel to use an
incorrect timer hwmod name if the selected GPTIMER was not 1 or 12 -
thanks Santosh.  Also, Tarun Kanti DebBarma <tarun.kanti@ti.com>
pointed out that the original patch did not apply cleanly; this has
now been fixed.

a2debdbd1a OMAP2+: hwmod: add ability to setup individual hwmods
Add omap_hwmod_setup_one(), which is intended for use early in boot to
selectively setup the hwmods needed for system clocksources and
clockevents, and any other hwmod that is needed in early boot.
omap_hwmod_setup_all() can then be called later in the boot process.
The point is to minimize the amount of code that needs to be run
early.

48d54f3fd2 OMAP2+: hwmod: ignore attempts to re-setup a hwmod
Previously, if a hwmod had already been set up, and the code attempted
to set up the hwmod again, an error would be returned.  This is not
really useful behavior if we wish to allow the OMAP core code to setup
the hwmods needed for the Linux clocksources and clockevents before
the rest of the hwmods are setup.  So, instead of generating errors,
just ignore the attempt to re-setup the hwmod.

Move the code that looks for the MPU initiator hwmod to run during
the individual hwmod _register() function.  (Previously, it ran after
all hwmods were registered in the omap_hwmod_late_init() function.)

This is done so code can late-initialize a few individual hwmods --
for example, for the system timer -- before the entire set of hwmods is
initialized later in boot via omap_hwmod_late_init().

There's no longer any reason why we should prevent multiple
calls to omap_hwmod_init().  It is now simply used to register an
array of hwmods.

This should allow a subset of hwmods (e.g., hwmods
handling the system clocksource and clockevents) to be registered
earlier than the remaining mass of hwmods.

51c404b2c5 omap4: prcm: Fix the CPUx clockdomain offsets
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base.
The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power
domain control register

Fix the same.

The autogen scripts is fixed thanks to Benoit Cousson

With the old value, the clockdomain code would access the
*_PWRSTCTRL.POWERSTATE field when it thought it was accessing the
*_CLKSTCTRL.CLKTRCTRL field.  In the worst case, this could cause
system power management to behave incorrectly.

3cf32bba8c OMAP: McBSP: Convert McBSP to platform device model
Implement McBSP as platform device and add support for
registering through platform device layer using resource
structures.

Later in this patch series, OMAP2+ McBSP driver would be modified to
use hwmod framework after populating the omap2+ hwmod database.

cd5038024d OMAP: hwmod: allow hwmod to provide address space accessible from SDMA
Adds support for resource API to get address space info other than just MPU.
The drivers can now use platform_get_resource_byname() to get resource of
type 'IORESOURCE_MEM' by name.

69dbf857c8 OMAP: mailbox: build device using omap_device/omap_hwmod
Remove static platform_device and resource data within
omap mailbox driver; use the one defined in the hwmod
database along with omap_device framework for device
build and registration.

Add device latency functions to be used, so clock can be
enabled and sysconfig is configured.

cbc9438075 OMAP2+: clocksource: fix crash on boot when !CONFIG_OMAP_32K_TIMER
OMAP2+ kernels built without CONFIG_OMAP_32K_TIMER crash on boot after the
2.6.38 sched_clock changes:

[    0.000000] OMAP clockevent source: GPTIMER1 at 13000000 Hz
[    0.000000] Unable to handle kernel NULL pointer dereference at virtual address 00000000
[    0.000000] pgd = c0004000
[    0.000000] [00000000] *pgd=00000000
[    0.000000] Internal error: Oops: 80000005 [#1] SMP
[    0.000000] last sysfs file:

[    0.000000] CPU: 0    Not tainted  (2.6.38-rc5-00057-g04aa67d #152)
[    0.000000] PC is at 0x0
[    0.000000] LR is at sched_clock_poll+0x2c/0x3c

Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and
clocksource resolution about three orders of magnitude higher than
with CONFIG_OMAP_32K_TIMER set.  The tradeoff is that the lowest
power consumption states are not available.

Fix by calling init_sched_clock() from the GPTIMER clocksource init code.
