Now that the GIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static.

In preparation of moving gic code to drivers/irqchip, remove the direct
platform dependencies on gic_raise_softirq. Move the setup of
smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask
function to trigger wake-up IPIs.

Pull ARM SoC fixes from Olof Johansson:
"People are back from the holiday breaks, and it shows. Here are a
bunch of fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups, a few
__init annotation fixes and some error handling improvement in
their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to
see here, mostly from the OMAP PM changes, but nothing overly crazy."

The IRQ array must be terminated by -1 and not by -1+OMAP_INTC_START
This led to having a resource list of 100s of IRQs.
Looks like this was caused by commit a2cfc509 (ARM: OMAP3+: hwmod: Add
AM33XX HWMOD data) that probably had some search and replace updates
done for the patch for sparse irq support.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc2/fixes
Some OMAP PRCM and sparse fixes against v3.8-rc1. A basic set of test
logs are available here:
http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/
The 3730 Beagle XM here has an intermittent failure mounting SD root,
but the suspicion right now is that this is due to a failing SD card,
rather than any change introduced by these patches.
This second version includes a few changes requested by Tony Lindgren.

On OMAP2xxx chips, the register bitfields for the
PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are
different than those used on OMAP3/4. The order is reversed. So, for
example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0
indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on
OMAP3/4, 0x3 indicates 'ON'.
To fix this, we treat the OMAP3/4 values as the powerdomain API
values, and create new low-level powerdomain functions for the
OMAP2xxx chips which translate between the OMAP2xxx values and the
OMAP3/4 values.
Without this patch, the conversion of the OMAP2xxx PM code to the
functional powerstate code results in a non-booting kernel.

The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order
to access the ETM/ETB hardware. The emu_src_ck should enable the EMU
clock domain so that the ETM/ETB hardware is accessible. However,
currently when enabling the emu_src_ck the EMU clock domain is not
being enabled and so the ETM/ETB drivers are failing. Add enable/disable
clock functions to enable the EMU clock domain when enabling the
emu_src_ck.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

"From Tony Lindgren:
Here are few more patches to finish the omap changes for multiplatform

Then there are several trivial fixes for typos and few minimal

Commit 2ac29a1 (ARM: PMU: fix runtime PM enable) moved the call to
pm_runtime_enable() from the OMAP2+ PMU code into the ARM PERF core
code. However, header for pm_runtime which should have been removed
from the OMAP2+ PMU code was not. It is no longer necessary to include
this header in the OMAP2+ PMU code and so remove it.

The cpu_is_omap macros are now local to arch/arm/mach-omap2
in soc.h and plat/cpu.h can finally be dropped for omap2+.
Thanks everybody for help with fixing the drivers.
Note that we can now also remove the unused plat/cpu.h from
smartreflex.c and isp.c as they will cause compile errors
with ARCH_MULTIPLATFORM enabled.

Looks like we missed plat-omap/fb.c for cpu_is_omap usage
mach-omap2. This is the last user of cpu_is_omap, so let's
quickly fix it up so we can finally remove plat/cpu.h for
omap2lus.
We want to limit cpu_is_omap macro usage to mach-omap2 only so
we can make plat/cpu.h private. After this we can finally drop
plat/cpu.h for omap2+.

Commit 787314c35fbb ("Merge tag 'iommu-updates-v3.8' of
git://git./linux/kernel/git/joro/iommu") did not account for the changed
header location.
The headers were made local to mach-omap2 as they are specific to omap2+
only, and we wanted to get most of the #include <plat/*.h> headers fixed
up anyways for the ARM multiplatform support.
We attempted to avoid this kind of merge conflict early on by setting up
a minimal git branch shared by the arm-soc tree and the iommu tree, but
looks like we still hit a merge issue there as the branches got merged
as various topic branches.

Pull IOMMU updates from Joerg Roedel:
"A few new features this merge-window. The most important one is
probably, that dma-debug now warns if a dma-handle is not checked with
dma_mapping_error by the device driver. This requires minor changes
to some architectures which make use of dma-debug. Most of these
changes have the respective Acks by the Arch-Maintainers.
Besides that there are updates to the AMD IOMMU driver for refactor
the IOMMU-Groups support and to make sure it does not trigger a
hardware erratum.
The OMAP changes (for which I pulled in a branch from Tony Lindgren's
tree) have a conflict in linux-next with the arm-soc tree. The
conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is
deleted in the arm-soc tree. It is safe to delete the file too so
solve the conflict. Similar changes are done in the arm-soc tree in
the common clock framework migration. A missing hunk from the patch
in the IOMMU tree will be submitted as a seperate patch when the
merge-window is closed."

This prevents hwmod _enable_clocks...omap2_dflt_clk_enable path
from enabling modulemode inside CLKCTRL using its clk->enable_reg
field. Instead is left to _omap4_enable_module though soc_ops, as
the one in charge of this setting.
According to comments received[1] for related patches the idea is
to get rid of leaf clocks in future. So remove these two while at it.

Use runtime PM functionality interfaced with hwmod enable/idle
functions, to replace direct clock operations and sysconfig
handling.
Due to reset sequence, pm_runtime_[get|put]_sync must be used, to
avoid possible operations with the module under reset. Because of
this and given that the driver uses spin_locks to protect their
critical sections, we must use pm_runtime_irq_safe in order for the
runtime ops to be happy, otherwise might_sleep_if checks in runtime
framework will complain.
The remaining pm_runtime out of iommu_enable and iommu_disable
corresponds to paths that can be accessed through debugfs, some of
them doesn't work if the module is not enabled first, but in future
if the mmu is idled withouth freeing, these are needed to debug.

Use hwmod data and device attributes to build and register an
omap device for iommu driver.
- Update the naming convention in isp module.
- Remove unneeded check for number of resources, as this is now
handled by omap_device and prevents driver from loading.
- Now unused, remove platform device and resource data, handling
of sysconfig register for softreset purposes, use default
latency structure.
- Use hwmod API for reset handling.

Pull ARM SoC fixes from Olof Johansson:
"This is a batch of fixes for arm-soc platforms, most of it is for OMAP
but there are others too (i.MX, Tegra, ep93xx). Fixes warnings, some
broken platforms and drivers, etc. A bit all over the map really."
There was some concern about commit 68136b10 ("RM: sunxi: Change device
tree naming scheme for sunxi"), but Tony says:
"Looks like that's trivial to fix as needed, no need to rebuild the
branch to fix that AFAIK.
The fix can be done once Olof is available online again.
Linus, I suggest that you go ahead and pull this if there are no other
issues with this branch."

Instead of using cpu_is_omap..() macros in the device driver we
rely on information provided in the platform data.
The only information we need is whether the USB Host module has
a single ULPI bypass control bit for all ports or individual bypass
control bits for each port. OMAP3 REV2.1 and earlier have the former.

Ethernet is not currently working on the OMAP2420 H4 board. In commit
f604931 (ARM: OMAP: abstract debug card setup (smc, leds)) the function
h4_init_smc91x() that initialised the ethernet controller was renamed to
h4_init_debug() but was never called when initialising the board.
Adding a call to h4_init_debug() fixes ethernet support, however,
instead of using the legacy H4 code migrate the H4 to use the
gpmc_smc91x_init() function instead and remove the legacy H4 code.

It is not correct for following platforms:
2430 - gpio mux mode 3
44xx - gpio mux mode 3
54xx - gpio mux mode 6
Patch reserves first 3 bits in partition flags for storing gpio mux
mode in same format as stored in control pad register.
Modified OMAP_MODE_GPIO() macro to handle all possible cases of gpio mux mode.
Modified omap_mux_init() flags of omap34xx to include OMAP_MUX_GPIO_IN_MODE4.

The i2c handling in tfp410 driver, which handles converting parallel RGB
to DVI, was changed in 958f2717b84e88bf833d996997fda8f73276f2af
(OMAPDSS: TFP410: pdata rewrite). The patch changed what value the
driver considers as invalid/undefined. Before the patch, 0 was the
invalid value, but as 0 is a valid bus number, the patch changed this to
-1.
However, the fact was missed that many board files do not define the bus
number at all, thus it's left to 0. This causes the driver to fail to
get the i2c bus, exiting from the driver's probe with an error, meaning
that the DVI output does not work for those boards.
This patch fixes the issue by changing the i2c_bus number field in the
driver's platform data from u16 to int, and setting the bus number to -1
in the board files for the boards that did not define the bus. The
exception is devkit8000, for which the bus is set to 1, which is the
correct bus for that board.
The bug exists in v3.5+ kernels.

This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove
CONFIG_OMAP_32K_TIMER) where the omap2_sync32k_clocksource_init() is no
longer referenced by the timer initialisation function for the AM335x

Fix this by adding the "__maybe_unused" compiler directive to the
omap2_sync32k_clocksource_init() function to indicate that this function
may be used for certain configurations.

In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time
counter), the function realtime_counter_init() was added. However, if
the kernel configuration option CONFIG_SOC_OMAP5 is not selected then
the following compiler warning is observed.
CC arch/arm/mach-omap2/timer.o
arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’
defined but not used [-Wunused-function]
Commit fa6d79d also introduced the kernel configuration option
CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the
a stub function for realtime_counter_init() is defined.
For non-OMAP5 devices, there is no realtime counter and so
realtime_counter_init() function and stub function are not used for
these devices. Therefore, fix this warning by only allowing the kernel
configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for
OMAP5 devices.

Commit d043d87 (ARM: OMAP2+: clockdomain: bypass clockdomain handling
when disabling unused clks) skips the decrementing of a clock-domains
use count if the clocks use count is zero. However, for OMAP4 devices
this is causing the EMU clock-domain to be stuck ON as the use count is
not getting decremented correctly.
The scenario that leads to this problem is described below ...
omap_hwmod_setup_all
--> _setup
--> clkdm_hwmod_enable
--> EMU clock domain usecount = 1
--> _enable_clocks
--> clk_enable
--> trace_clk_div_div usecount = 1
--> clkdm_hwmod_enable
--> EMU clock domain usecount = 2
--> _idle
--> _disable_clocks
--> clk_disable
--> trace_clk_div_div usecount = 0
--> clkdm_hwmod_disable
--> skips decrement of EMU clock domain usecount
because trace_clk_div_div is 0!
--> EMU clock domain usecount = 2
--> clkdm_hwmod_disable
--> EMU clock domain usecount = 1
Hence, due to the order that a clocks use count is decremented and the
clock domain is disabled, it is possible that the clock domain can have
a non-zero use count when the actual clock has a use count of 0.
Therefore, we should only bypass the clock-domain handling when both the
clock-domain and clock in the clock-domain have a use count of 0 and
warn when the clock-domain has a zero use count and the clock has a
non-zero use count.

With the latest mainline u-boot bootloader (v2012.10), timers (5-8) in
the ABE power domain are failing to turn-on. The timers never come out
of the disabled state when setting the module-mode field to enable.
The problem was exposed when u-boot was updated to NOT configure and
lock the ABE DPLL on start-up. If the ABE DPLL is configured and locked
by u-boot the problem does not occur. However, if the ABE DPLL is in the
idle low-power bypass state and we attempt to enable a timer in the ABE
power domain, it remains stuck in the disabled state. It appears to be a
problem the timer interface clock as this comes from the ABE DPLL.
If we place the ABE DPLL in the MN-bypass state and not the idle
low-power state, then this problem is not seen.
This problem only appears to occur on OMAP4460 and not OMAP4430.
Workaround this problem by locking the ABE DPLL for OMAP4460 in the
kernel on boot. By locking the ABE DPLL, when clocks from the ABE DPLL
are not being requested the DPLL will transition into a low-power stop
mode.

On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can
be enabled or disabled in addition to the standard configurable
multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X
multiplier is accounted for by checking to see whether it is enabled or
not. However, when calculating a new rate we only check to see if the
rate can be achieved with the current setting for the 4X multiplier.
Enhance the round_rate() function for such DPLLs to see if the rate
can be achieved with the 4X multiplier if it cannot be achieved without
the 4X multiplier.
This change is necessary, because when using the 32kHz clock as the
source clock for the ABE DPLL, the default DPLL frequency for the ABE
DPLL cannot be achieved without enabling the 4X multiplier.
When using the 32kHz clock as the source clock for the ABE DPLL and
attempting to lock the DPLL to 98.304MHz (default frequency), it was
found that the DPLL would fail to lock if the low-power mode for the DPLL
was not enabled. From reviewing boot-loader settings that configure the
ABE DPLL it was found that the low-power mode is enabled when using the
32kHz clock source, however, the documentation for OMAP does not state
that this is a requirement. Therefore, introduce a new function for
OMAP4 devices to see if low-power mode can be enabled when calculating a
new rate to ensure the DPLL will lock.
New variables for the last calculated 4X multiplier and low-power
setting have been added to the dpll data structure as well as variables
defining the bit mask for enabling these features via the DPLL's
control_reg. It is possible that we could eliminate these bit masks from
the dpll data structure as these bit masks are not unique to OMAP4, if
it is preferred.
The function omap3_noncore_program_dpll() has been updated to avoid
passing the calculated values for the multiplier (M) and divider (N) as
these are stored in the clk structure.

Currently all OMAP4 non-core DPLLs use the same function table for
configuring DPLLs. For these DPLLs, the function
omap4_dpll_regm4xen_recalc() is used to recalculate the DPLL rate and
the function omap4_dpll_regm4xen_round_rate() is used to calculate the
closest rate to that requested. However, these omap4_dpll_regm4xen_xxx()
functions are only applicable to the ABE DPLL and not the other non-core
DPLLs. Therefore, add a new function table for non-core DPLLs that do
not include the 4X-multiplier (M4X).
Please note that using these omap4_dpll_regm4x_xxx() function works for
the non-M4X DPLLs today because we only check to see if the 4X
multiplier is enabled when calculating the rate. However, it is planned
that the dpll functions will be enhanced to enable the 4X multiplier as
necessary (in order to achieve the requested rate) and so calling these
functions for non-M4X dplls will no longer work.

Commit "ARM: dts: OMAP4: Update timer addresses" updated the device-tree
names of the OMAP4 timers 5-7 because the default address for the timers
was changed from the L3 address to the MPU private address. When booting
with device-tree, this introduces a regression when attempting to set
the parent clock of timers 5-7 to the sys_clk_div_ck. Therefore, update
the clock aliases for timer 5-7 to reflect the updated device-tree name
for the timers.
