Use devm_ioremap_resource and devm_kzalloc to simplify error
paths and reduce lines of code. Also use dev_err() to keep
consistency and drop the .remove function because the devm
functions take care of what it's doing besides the now obsolete
platform_set_drvdata() which we can just drop. Finally, use
module_platform_driver() to save some more lines.

The genirq IRQ wake method will default to failure if the irq_chip
does not provide a set_wake method. However, for TWL4030 sub-chip
IRQs, we want the wake enable to succeed even though we don't provide
a set_wake method. This allows sub-chip IRQs to still be flagged as
wakeup capable, and allow them to wakeup from suspend (or abort
suspend if they fire during suspend.)
To fix, use the IRQCHIP_SKIP_SET_WAKE flag in the irq_chip.

The TSC part allows to specify the input lines. The IIO part assumes
that it usues always the last few, that means if IIO has adc-channels
set to 2 it will use channel 6 and 7. However it might make sense to use
only 6.
This patch changes the device property (which was introduced recently
and was never in an official release) in a way that the user can specify
which of the AIN lines should be used. In Addition to this, the name is
now AINx where x is the channel number i.e. for AIN6 we would have 6.
Prior this, it always started counting at 0 which is confusing. In
addition to this, it also checks for correct step number during reading
and does not rely on proper FIFO depth.

The mfd driver creates platform data for the child devices and it is the
ti_tscadc_dev struct. This struct is copied for the two devices.
The copy of the structure makes a common lock in this structure a little
less usefull. Therefore the platform data is not a pointer to the
structure and the same structure is used.
While doing the change I noticed that the suspend/resume code assumes
the wrong pointer for ti_tscadc_dev and this has been fixed as well.

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core. It only is useful
for cpufreq drivers for their internal purposes.
Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0. If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.
Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.
To reduce overall code bloat, make the changes described above.

It's bigger than I would like, most of it is due to the big ab/db8500 merge
that went through during the 3.10 merge window.
So we have:
- Some build fixes for the tps65912 and ab8500 drivers.
- A couple of build fixes for the the si476x driver with pre 4.3 gcc
compilers.
- A few runtime breakage fixes (probe failures or oopses) for the ab8500
and db8500 drivers.
- Some sparse or regular gcc warning fixes for the si476x, ab8500 and
cros_ec drivers.

Previously the DSI PLL divider rate was initialised statically and
assumed to be 1. Before the common clock framework was enabled for
ux500, a call to clk_set_rate() would always update the HW registers
no matter what the current setting was.
This patch makes sure the actual hw settings and the sw assumed
settings are matched.

AB8500 sysctrl driver implements a pm_power_off handler, but that is
currently not registered until a specific platform data field is
enabled.
This patch drops the platform data field and always registers
ab8500_power_off if no other pm_power_off handler was defined before,
and also introduces the necessary cleanup code in the driver's remove
function.

When booting with Device Tree enabled the MFD core uses each device's
compatible string to find and allocate its associated of_node pointer,
which in turn is passed to the driver via the platform_device struct.
Without it, the driver won't be able to interrogate the Device Tree or
locate suitable regulators and will most likely fail to probe.

The MFD subsystem requires drivers to state the size of any platform
data passed, or it will fail to assign it to the device. This will
culminate in a NULL platform_data attribute and normally a failure to
probe() or a kernel Oops.

When we're using Device Tree to enable GPIO drivers we're forced to be
OS agnostic, thus we are forbidden use names like pinctrl as they are
specific only to Linux, at least for the time being. However, when we
are registering devices using internal systems such as MFD or platform
registration, we can use such terminology. In this case we can and
should use the platform device ID mechanism to specify which device we
wish to utilise by detailing pinctrl-<device_name>.
This patch fixes a regression that when booting with Device Tree
enabled the ABx500 GPIO/Pinctrl devices are not probed.

The AB8500 debug code which was merged in parallell with the
multiplatform work incidentally introduced a new instance using
the <mach/irqs.h> header which is now deleted, causing this
build regression:
drivers/mfd/ab8500-debugfs.c:95:23:
fatal error: mach/irqs.h: No such file or directory
compilation terminated.
make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1
The code most certainly never worked with device tree either
since that does not rely on this kind of hard-coded interrupt
numbers.
Fix the problem at the root by passing it as a named resource
from the ab8500-core driver. Use an untyped resource to
stop the MFD core from remapping this IRQ relative to the
AB8500 irqdomain.

this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was a
patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then.

platform devices yet. After this stage is complete we can then
fill in the inadequacies, such as specific clock support at a

all platforms into a common device structure and the remaining
ones into a platform specific one.

For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

AB8500 asserts LATCH bits for masked out interrupts. This patch
explicitly masks those out using the cached mask value to prevent
handle_nested_irq() being called for masked IRQ on the same register as
unmasked ones.

Twelve Kconfig symbols, all related to WM8350, WM8351, and WM8352, are
unused. Commit 19d57ed5a3 ("mfd: Remove
custom wm8350 cache implementation") removed all their (actual) users.
Remove these symbols too.

This patch changes the irq state from high to the now default low.
Because the default PMIC irq state of DA9055 got changed from high to low.
This change should not affect any of the existing users since all of them
use active low state.
This patch has been tested on smdkv6410.
