Add irqdomains for max8925's main irq, wrap irq register operations
into irqdomain's map func. it is necessary for dt support.
Also, add dt support for max8925 driver.

The vexpress_sysreg_init() is a core_initcall() already and it can
trigger the early initialisation if a matching node is found. This patch
allows the SoC code to avoid calling vexpress_sysreg_of_early_init()
explicitly.

Implement different ways of selecting driving capability(a necessary adjustment
along with voltage change). It was origionally in device-independent
mmc/host/rtsx_pci_sdmmc.c. Moving it here to support devices which may have a
different way of adjustment.

1. Schedule card detect work at the end of the ISR
2. Callback function ops->cd_deglitch may delay for a period of time.
It is not proper to call this callback when local irq disabled.
3. Card detect flow can't be executed in parallel with other card reader
operations, so it's better to be protected by mutex.

In function rtsx_pci_switch_clock, some variables, such as min_n, max_n,

obscure for others. It's more proper to use macro definitions here to

The tps65090 mfd driver implement the suspend/resume callbacks
which just disable and enable irqs in suspend/resume respectively.
This operation is already done in irq suspend and irq_resume and
hence it is not require to implement the same in the driver.
Remove this non-require code.

When device is get added through DT then irq_base is 0 (zero)
and in this case regmap_irq_chip_get_base() generates warning.
The interrupt of this device get added through irq_domain_add_linear()
when irq_base is 0.
Hence pass the irq domain in place of base_irq when calling
mfd_add_devices().

Runtime power management does not function during system suspend but the
Arizona devices need to use runtime power management to power up the device
in order to handle interrupts. Try to avoid interrupts firing during
resume by disabling the primary IRQ before interrupts are reenabled on
resume and only reenabling it again during main resume.
The goal is to avoid issues in the situation where an interrupt is asserted
during resume (eg, due to it being the wake source) and the interrupt
handling gets scheduled prior to the device being able to handle runtime
PM.

Palma RTC is capable of generating alarm interrupt. Pass the alarm interrupt
as IRQ_RESOURCE for palmas-rtc sub device driver so that rtc driver can get
irq as platform_get_irq().
Also pass the irq domain in mfd_add_devices() to properly offset the irqs for
sub devices. This is needed when adding device through DT.

Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

From Linus Walleij:
Removal of the <mach/id.h> include from ux500
- First an ACKed MFD patch deleting the only consumer
of these cpu_is* functions outside of mach-ux500
- Introduce a new local cpu_is_u8580() in this patch
set to avoid clashing with other patch sets.
- Finally de-globalize <mach/id.h>.

This removes the file <mach/id.h> from the global kernel include
scope, making it a pure mach-ux500 detail. All ASIC specifics
needed by drivers shall henceforth be passed from either platform
data or the device tree.
