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.

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>

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.

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.

Disable autoidle on all clocks during clock framework initialization.
(If CONFIG_PM is set, autoidle is re-enabled for all clocks later in
the boot process.)
The principle behind this patch, and some similar patches, is that the
kernel should start with all power management features disabled.
Later in the boot process, the PM code, if compiled in with CONFIG_PM,
enables or re-enables power management features.

On OMAP4, the dpll post divider outputs (MX outputs)
along with clockout_x2 output provide a way to allow/deny
hardware level autogating.
Allowing autoidle would mean that the hw would autogate
this clock when there is no dependency for it.
Denying idle would mean that this clock output will be
forced to stay enabled.
Add dpll api's to read/allow/deny idle control
for these dpll mx postdividers.
NOTE: The gatectrl bit set to 0 allows gatectrl,
and the bit set to 1 denies gatectrl.

Attempt to enable autoidle for as many clocks as possible in the
OMAP2+-common CONFIG_OMAP_RESET_CLOCKS code. Currently, this only
enables DPLL autoidle for OMAP3/4 DPLLs; but future patches will
enable autoidle for other clocks and the OMAP2 DPLL/APLLs.
In the long run, we should probably get rid of
CONFIG_OMAP_RESET_CLOCKS, and unconditionally run the code that it
selects. Otherwise, the state of the clock tree won't match the
hardware state - this could result in clocks being enabled or disabled
unpredictably.
Based on a patch by Rajendra Nayak <rnayak@ti.com> that did this in
the pm34xx.c/pm44xx.c code.
