Save a useful amount of code by removing the custom cache implementation
for wm8400 and using the regmap cache. Also simplify things by not
separately reseting the CODEC registers, this is a sufficiently infrequent
operation that we can simply invalidate the entire cache when this happens.Signed-off-by: Mark Brown

The tps65910_parse_dt() prototype for !CONFIG_OF was not correct, leading to:

During regmap initialization, we do not provide the default value and
hence in place of caching register during regmap_init(), cache it
when actually we need it i.e. after reading of that register.Signed-off-by: Laxman Dewangan

twl-regulator has a collection of feature flags, some defined
in twl-core.c and one defined in i2c/twl.h.
This is confusing for anyone adding a new feature flag.So collect them together and place them in twl.h immediately
after the structure in which they are initially set.Signed-off-by: NeilBrown

This change removes the read/write callback functions in favor of common
regmap accessors inside the header file. This change also makes use of
regmap_read/write for single register access which maps better onto what this
driver actually needs.Signed-off-by: Rhyland Klein

Hierarchical interrupt is supported since ab8500 V2.
However, it is not implemented in the ab8500-core driver.
With the current implementation, when an ab9540 interrupt
occurs, 17 Latch registers are read through i2c. With
hierarchical interrupt implementation, there are only 4 i2c
accesses.Signed-off-by: Maxime Coquelin

twl6040 has three power supply source:
VBAT needs to be connected to VBAT, VIO, and V2V1.
Add regulator support for the VIO, V2V1 supplies.

Most of the interrupts that come through this line should trigger
wakeups:
power button
RTC alarm
power available
usb plug/unplugso mark the interrupt as a wakeup interrupt.
This is particularly important for when the interrupt arrives during
the late suspend phase. Without this setting it will be ignored.Signed-off-by: NeilBrown

Since it's not like we will re-arrange the keys at run-time, it

This patch will enable probing to occur during a Device Tree enabled

from the DT itself. We also prevent any of the db8500 regulators
from being registered here, as they will be enabled via DT instead.Signed-off-by: Lee Jones

The removal of mach/io.h from most ARM platforms also set the range of
valid IO ports to be empty for most platforms when previously any 32
bit integer had been valid. This makes it impossible to add IO resources
as the added range is smaller than that of the root resource for IO ports.Since we're not really using IO memory at all fix this by defining our
own root resource outside the normal tree and make that the parent of
all IO resources. This also ensures we won't conflict with read IO ports
if we ever run on a platform which happens to use them.Signed-off-by: Mark Brown

A warning was being generated by the reference from tps65910_i2c_probe()
to tps65910_sleepinit() since the latter was annotated as __init but the
former was unannotated. Since these functions can only be called during
device init make them both __devinit, and while we're at it also annotate
tps65910_i2c_remove() __devexit for symmetry.Signed-off-by: Mark Brown
