There is no point in completing probe if platform data is missing so
let's abort loading early.Also, use kcalloc when allocating several instances of the same data
structure and mark setup_regulators() as __devinit since it is only
called from lp3971_i2c_probe() which is __devinit.Signed-off-by: Dmitry Torokhov

Add __devinit/__devexit markings to probe and remove methids of the

Probe and remove methods should not be marked as __init/__exit but
rather __devinit/__devexit so that the needed sections stay in memory
in presence of CONFIG_HOTPLUG. This is needed even on non hotpluggable
buses.Signed-off-by: Dmitry Torokhov

This is no REMAP register on twl6030, instead there is a STATE register
to drive a resource to a given state.
The state register can be used to specify what state the resource should
enter when its associated with a GRP.
Register Bit field description is as below. The patch programmes the
corresponding STATE registers for all LDO's to turn ON when assocaited
with GRP_P1.STATE REG:
Bit7 |Bit6 |Bit5 |Bit4 |Bit3 |Bit2 |Bit1 |Bit0
P3_GRP |P2_GRP |P1_GRP |RES |RES |RES |State1 |State0State can be specified as below

In order to ease transitions with drivers are boards start using regulators
provide an option to cause all regulator_get() calls to succeed, with a
dummy always on regulator being supplied where one has not been configured.
A warning is printed whenever the dummy regulator is used to aid system
development.This regulator does not implement any regulator operations but will allow
simple consumers which only do enable() and disable() calls to run. It
is kept separate from the fixed voltage regulator to avoid Kconfig
confusion on the part of users when it is extended to allow boards to
explicitly use the dummy regulator to simplify cases where the majority
of supplies are from fixed regulators without software control.This option is currently only effective for systems which do not specify
full constriants. If required an override could also be provided to allow
these systems to use the dummy regulator, though it is likely that
unconfigured supplies on such systems will lead to error due to
regulators being powered down more aggressively when not in use.Signed-off-by: Mark Brown

If a regulator driver does not provide a way to query if the driver is
enabled then assume that it is enabled. This is very likely to reflect

GPO regulators are digital outputs that can be enabled or disabled by a
dedicated bit in mc13783 POWERMISC register.
In this family can be count in also Power Gates (PWGT1 and 2): enabled by
a dedicated pin a Power Gate is an hardware driven supply where the output
(PWGTnDRV) follow this law:Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV | Read Back
0 = default | | | PWGTxSPIEN
---------------+-------------+----------+------------
1 | x | Low | 0
0 | 0 | High | 1
0 | 1 | Low | 0As read back value of control bit reflects the PWGTxDRV state (not the
control value previously written) and mc13783 POWERMISC register contain
only regulator related bits, a dedicated function to manage these bits is
created here with the aim of tracing the real value of PWGTxSPIEN bits
and reproduce it on next writes.All POWERMISC users _must_ use the new function to not accidentally
disable Power Gates supplies.v2 changes:
-Better utilization of abstraction layers.
-Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator
with voltage value of 3.1V and 5.5V respectively.Signed-off-by: Alberto Panizzo

Regulators may sometimes take longer to enable than the control operation
used to do so, either because the regulator has ramp rate control used to
limit inrush current or because the control operation is very fast (GPIO
being the most common example of this). In order to ensure that consumers
do not rely on the regulator before it is enabled provide an enable_time()
operation and have the core delay for that time before returning to the
caller.This is implemented as a function since the ramp rate may be specified in
voltage per unit time and therefore the time depend on the configuration.
In future it would be desirable to allow the bulk operations to run the
delays for multiple enables in parallel but this is not currently supported.Signed-off-by: Mark Brown

The intended use case is for drivers which disable regulators to save
power but need to do some work to restore the hardware state when
restarting. If the supplies are not actually disabled due to board
limits or sharing with other active devices this notifier allows the
driver to avoid unneeded reinitialisation, particularly when used with
runtime PM.Signed-off-by: Mark Brown

This patch, complete the mc13783 regulator subsystem driver with
voltage selecting capability.
Main Switches (SW1AB, SW2AB) are not supported yet.version 2 diffs:
- delete the "Switchers PLL" enable and multiplication factor value
selecting capability because it is not a voltage or current regulator.
This will be a part of Main switcher supporting task.

In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
