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.

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.

In the AB8500 IRQ mask and unmask functions, we rely on testing for
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to
physically mask and unmask the correct interrupt lines. In order
for us to do that, the trigger needs to be set in the associated
flags. However, unless a irq_set_type() function pointer is passed
when registering the IRQ chip, the IRQ subsystem will refuse to do
it. For that reason, we're providing one.

The patch:
"mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly"
altered the AB8500 IRQ mask/unmask functions such that they
would handle masking on/off the falling edge IRQ if this was
requested by the consumer. However the bit mask for hwirqs
43 and 44 was shifting the bit mask incorrectly, resulting in
the wrong IRQ being mased/unmasked.
Further while the patch would mask/unmask the correct line,
when the interrupt actually came in, it would still be treated
as a valid hwirq. The offsetting applied when masking/unmasking
was not applied when handling the IRQ, i.e. the falling edge
lines were not routed back to the rising edge lines.
This fixes both cases. The end result has been tested with
the SIM detect IRQ, GPIO12, hwirq 46 and 62.

In an upcoming patch, the gpio-ab8500 driver will relinquish all
IRQ handling capability and pass it back into the AB8500 core
driver. This will aid in reducing massive code duplication within
the kernel. Also, most of the functionality is already in the
AB8500 core driver, as the GPIO IRQs are actually sandwiched
between lots of other IRQs which the core driver already handles.
All we're doing here is providing the core driver with knowledge
that each GPIO has two IRQs assigned to it; one for rising and
a separate one for falling.

If the twl4030_write_script function gets called with
a zero length argument, its return value does not
get set. We know that all scripts have a nonzero
length, but returning an error in case they ever
do is probably appropriate.
Without this patch, building omap2plus_defconfig results in:
drivers/mfd/twl4030-power.c: In function 'load_twl4030_script':

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.
The failure case is where this unwanted write transfers incorrect data to
a critical register.
This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.
