This patch replaces platform_add_devices of DSS with omap_display_init().
This moves away registration of DSS from board files into a common place.

Currently voltage values on opp tables are hardcoded. As these voltage values
are anyway defined in voltage.h as macros, opp table can reuse these values.
This will avoid opp table and voltage layer having conflicting values.

There could be dependencies between various voltage domains for
maintaining system performance or hardware limitation reasons
like VDD<X> should be at voltage v1 when VDD<Y> is at voltage v2.
This patch introduce dependent vdd information structures in the
voltage layer which can be used to populate these dependencies
for a voltage domain. This patch also adds support to scale
the dependent vdd and the scalable devices belonging to it
during the scaling of a main vdd through omap_voltage_scale.
As part of this, some of the voltage layer structure definitions are moved from
voltage.c to voltage.h as it needs to be used in the dvfs layer for dependency
voltage handling.

This patch introduces an API to perform DVFS for a given voltage domain.
It takes omap_vdd_dvfs_info pointer as input parameter, computes the highest
requested voltage for that vdd and scales all the devices in that vdd to the
requested frequency along with voltage scaling.

This patch extends the omap_device structure to contain pointers to scale the
operating rate of the device and to retrieve the operating rate of the device.
This patch also adds the three new APIs in the omap device layer
namely omap_device_set_rate that can be called to set a new operating
rate for a device, omap_device_get_rate that can be called to retrieve
the operating frequency for a device and omap_device_register_dvfs_callbacks
to register the device specific set_rate and get_rate functions.
The omap_device_set_rate and omap_device_get_rate does some routine error
checks and finally calls into the device specific set_rate
and get_rate APIs populated through omap_device_populate_rate_fns.

This patch introduces accessory APIs for DVFS.
Data structures added:
1. omap_dev_user_list: This structure maintains list of frequency requests per
device basis. When a device needs to be scaled to a particular frequency,
This list is searched to find the maximum request for a given device.
If noone has placed any request, device frequency is obtained from device
opp table.
2. omap_vdd_dev_list: This strcucture stores device list per vdd basis.
Whenever a device is registered with a vdd, it is added to this list.
3. omap_vdd_user_list: User list of devices associated with each voltage domain
instance. The user list is implemented using plist structure with priority
node populated with the voltage values.
4. omap_vdd_dvfs_info: This structure is used to abstract DVFS related
information per VDD basis. It holds pointer to corresponding vdd's
voltagedomain instance and pointer to user list.
Following APIs have been added to operate on above data structures:
1. omap_dvfs_add_vdd_user - API to add a user into omap_vdd_user_list
2. omap_vdd_user_list - API to remove a user from omap_vdd_user_list
3. omap_dvfs_register_device - API to register a device with vdd
4. omap_dvfs_add_freq_request - API to add a frequency request into
omap_dev_user_list
5. omap_dvfs_remove_freq_request - API to remove a frequency request from
omap_dev_user_list
6. omap_dvfs_find_voltage - API to find the opp corresponding to given voltage
DVFS layer is initialized and basic data structures are allocated and
initialized as part of this.
This patch is based on Thara's previous DVFS implementation, but with major
rework.

Voltage control on TWL can be done using VMODE/I2C1/I2C_SR.
Since almost all platforms use I2C_SR on omap3, omap3_twl_init by
default expects that OMAP's I2C_SR is plugged in to TWL's I2C
and calls omap3_twl_set_sr_bit. On platforms where I2C_SR is not connected,
the board files are expected to call omap3_twl_set_sr_bit(false) to
ensure that I2C_SR path is not set for voltage control and prevent
the default behavior of omap3_twl_init.

Expose clock debug information to debugfs, which makes it easier for clock
system debug by using tools like powerdebug developed by Linaro power
management group.
For long term, this can go into common clock framework, but so far it depends
on the process of common clk API development. Once the common clk API is
ready in upstream, the clock debug information will be based on it too.
The implementation based on common clk API had also been finished and
reviewed with Jeremy.

We need to delay freeing any mapped page on SMP and ARMv7 systems to
ensure that the data is not accessed by other CPUs, or is used for
speculative prefetch with ARMv7. This includes not only mapped pages
but also pages used for the page tables themselves.
This avoids races with the MMU/other CPUs accessing pages after they've
been freed but before we've invalidated the TLB.

When SMP_ON_UP is used and the spinlocks are inlined, we end up with
inline spinlocks in the exit code, with references from the SMP
alternatives section to the exit sections. This causes link time
errors. Avoid this by placing the exit sections in the init-discarded
region.

Commit 18991197b4b588255ccabf472ebc84db7b66a19c added --build-id
linker option when toolchain supports it. ARM one does, but for some
reason places the section at 0 when linker script doesn't mention it
explicitly.
The 1e621a8e3752367d4aae78a8ab00a18fb2793f34 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.
This problem was discussed here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.
This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).
It is enough to place it correctly in vmlinux (so debuggers are happy):
Section Headers:
[11] .data PROGBITS c07ce000 7ce000 020fc0 00 WA 0 0 32
[12] .notes NOTE c07eefc0 7eefc0 000024 00 AX 0 0 4

This reverts commit 9b29050f8f75916f974a2d231ae5d3cd59792296.
It has caused hibernate regressions, for example Juri Sladby's report:
"I'm unable to hibernate 2.6.37.1 unless I rmmod tpm_tis:

and Rafael points out that some of the new conditionals in that commit
seem to make no sense. This commit needs more work and testing, let's

broadcasted operation
On versions of the Cortex-A9 prior to r3p0, an interrupted ICIALLUIS
operation may prevent the completion of a following broadcasted
operation if the second operation is received by a CPU before the
ICIALLUIS has completed, potentially leading to corrupted entries in
the cache or TLB.
This workaround sets a bit in the diagnostic register of the Cortex-A9,
causing CP15 maintenance operations to be uninterruptible.
