omap3: Prevent SDRC deadlock when L3 is changing frequency
When changing the L3 clock frequency, the CPU is executing from internal RAM
and the SDRC clock is disabled. During this time accesses made to external
DDR are stalled. If the ARM subsystem attempts to access the DDR while the
SDRC clock is disabled this will stall the CPU until the access to the SDRC
timeouts. A timeout on the SDRC should never occur. Once a timeout occurs all
the following accesses will be aborted and the DDR is no longer accessible.
Although the code being executed in the internal RAM does not directly access
the DDR, it was found that the branch prediction logic in the CPU may cause
the CPU to prefetch code from a DDR location while the SDRC clock is disabled.
This was causing an SDRC timeout which resulted in a system hang.
This patch fixes this problem by ensuring the branch prediction logic is
disabled while changing the L3 clock frequency. The branch prediction logic
is disabled by clearing the Z-bit in the ARM CTRL register.
Disabling the branch prediction logic does not have any noticable impact
on the execution time of this code section. The hardware observability
signals were used to monitor the sdrc idle time with and without this
patch when operating at different CPU frequencies (150MHz, 500MHz and
600MHz) and the total sdrc idle time when changing frequenct was in
the range of 9-11us. This was measured on an omap3430 SDP running the
omapzoom p-android-omap-2.6.29 branch.

The explaination from the TRM for the idlest bits on OMAP4 is as
below for quick reference
Module idle state:
0x0 func: Module is fully functional, including OCP
0x1 trans: Module is performing transition: wakeup, or sleep, or sleep
abortion
0x2 idle: Module is in Idle mode (only OCP part). It is functional if
using separate functional clock
0x3 disabled: Module is disabled and cannot be accessed

OMAP: omap_device: Fix to support multiple hwmods for a single device
Currently there is a bug in the existing omap_device core code when
extracting the hwmod structures passed to omap_device_build_ss(). This bug
gets exposed only when passing multiple hwmod structures to
omap_device_build_ss() resulting in incorrect extraction from second hwmod
structure.
This fix uses the pointer to pointer to omap_hwmod structure (array of
pointers to omap_hwmod structure) passed to omap_device_build_ss() to
correctly extract the appropriate omap_hwmod structure.
This patch has been created and tested on lo/master and mainline.

In the idle path, we just do a single clk_disable() of the bank's
debounce clock. If there are multiple debounce-enabled GPIOs in the
bank, that clocks usage count will be > 1, so the clk_disable() will
not actually disable the clock.
So the fix is to clk_disable() for every debounce-enabled GPIO in the
bank (and an equivalent clk_enable() of course.)

OMAP4: pm: Change l3_main to l3_main_1 during bus device init
The OMAP4 L3 interconnect is split in 3 part for power saving reason.
Because of that there is no l3_main like on OMAP2 & 3 but 3 differentes
l3_main_X instances.
In the case of OMAP4, query only the l3_main_1 part. The clock and
voltage are shared across the 3 instances.

OMAP: omap_device: make all devices a child of a new parent device
In order to help differentiate omap_devices from normal
platform_devices, make them all a parent of a new common parent
device.
Then, in order to determine if a platform_device is also an
omap_device, checking the parent is all that is needed.
Users of this feature are the runtime PM core for OMAP, where we need
to know if a device being passed in is an omap_device or not in order
to know whether to call the omap_device API with it.
In addition, all omap_devices will now show up under /sys/devices/omap
instead of /sys/devices/platform

Revert "OMAP: omap_device: add omap_device_is_valid()"
This reverts commit
0007122ad85cc36b1c18c0b59344093ca210d206.
The dereference method of checking for a valid omap_device when
wrapping a platform_device is rather unsafe and dangerous.
Instead, a better way of checking for a valid omap-device is
to use a common parent device for all omap_devices, then a check
can simply be made using the device parent. The only user of this
API was the initial version of the runtime PM core for OMAP. This
has now been switched to check device parent, so there are no more
users of this API.

OMAP clockdomain: initialize clockdomain registers when the clockdomain layer starts
When the clockdomain layer initializes, place all clockdomains into
software-supervised mode, and clear all wakeup and sleep dependencies
immediately, rather than waiting for the PM code to do this later.
This fixes a major bug where critical sleep dependencies added by the
hwmod code are cleared during late PM init.
As a side benefit, the _init_{wk,sleep}dep_usecount() functions are no
longer needed, so remove them.
Kevin Hilman <khilman@deeprootsystems.com> did all the really hard work on
this, identifying the problem and finding the bug.
