Note that this patch also leaves out the spurious IRQ warning
for omap3.
This warning should no longer be needed as the interrupt handlers
for various devices have implemented the necessayr read-back of

Currently, omap_display_init() maintains arrays for hwmod name(oh_name) and the
correspnding platform_device name(dev_name) needed by omap_device_build().
A variable oh_count keeps a track of the number of devices to build from oh_name
based on what omap revision it is.
Clean this up by maintaining an array of omap_dss_hwmod_data struct which is
defined for each omap revision as suggested by Tomi Valkeinen. Assign the
corresponding omap_dss_hwmod_data array struct to the pointer curr_dss_hwmod in
omap_display_init().

In commit 7538e3db6e (PM: add support
for device power domains) a better way for handling platform-specific
power hooks was introduced.
Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.
Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)
[rjw: Rebased on top of a previous change modifying the handling of
power domains by the PM core so that power domain callbacks take
precendence over subsystem-level PM callbacks.]

Blindly setting 1.2V in the initial structure may not even match the
default voltages stored in the voltage table which are supported for
the domain. For example, OMAP3430 core domain does not use 1.2V and
ends up generating a warning on the first transition.
Further, since omap2_set_init_voltage is called as part of the pm
framework's initialization sequence to configure the voltage required
for the current OPP, the call does(and has to) setup the system
voltage(curr_volt as a result) using the right mechanisms appropriate
for the system at that point of time. This also overrides
initialization we are currently doing in voltage.c making it
redundant. So, remove the wrong and redundant initialization.

As per OMAP3 erratum (i671), ROM code adds extra latencies while
restoring CM_AUTOIDLE_PLL register, if AUTO_PERIPH_DPLL is equal to 1.
This patch stores 0's in scratchpad content area corresponding to
AUTO_PERIPH_DPLL, to prevent ROM code to try to lock per DPLL, since
it won't respect proper programing scheme.
This register is then stored in prcm context. The saving and restore
is now done by kernel side.
Here follow the erratum description
DESCRIPTION
After OFF mode transition, among many restorations, the ROM Code restores the
CM_AUTOIDLE_PLL register, and after that, it tries to relock the PER DPLL.
In case the restoration data stored in scratchpad memory contains a field
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL = 1, then the way the ROM Code restores and
locks the PER DPLL does not respect the PER DPLL programming scheme.
In that case, the DPLL might not lock. Meanwhile, when trying to lock the PER
DPLL, the ROM Code does not hang. Only extra latencies are introduced at
wake-up.
WORKAROUND
When saving the context-restore structure in scratchpad memory, in order to
respect the PER DPLL programming scheme, it is advised to store 0 in the
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL field of the saved structure.
After wake-up, the application should store in CM_AUTOIDLE_PLL register the
right desired value.

DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and
running, and also to get the pixel clock's source clock rate from the
fck.
On OMAP4 the clock data is set up in a different way, as there's no ick,
dss_fck points to a fake clock which just affects DSS's MODULEMODE, and
dss_dss_clk if the DSS_FCK.
>From DSS driver's point of view the dss_fck sounds like an ick, and
dss_dss_clk is the fck. While this is not entirely correct from HW point
of view, especially for the ick, configuring the clock aliases that way
makes DSS "just work" with OMAP4's clock setup.
In the (hopefully near) future DSS driver will be reworked to use
pm_runtime support which should clean up the clock code.

Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h
