regulator: palmas: Remove *rdev[PALMAS_NUM_REGS] from struct palmas_pmic
This driver is using devm_regulator_register() so it is not necessary
to save *rdev for clean up. Actually the pmic->rdev[id] is not used now.

Keerthy 572ff4d560 mfd: palmas: Assign the right powerhold mask for tps65917
The powerhold mask for TPS65917 is different when comapred to
the other palmas versions. Hence assign the right mask that enables
power off of tps65917 pmic correctly.

Chanwoo Choi 176aa36012 extcon: Split out extcon header file for consumer and provider device
The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect the
   state/properties of external connector. Also, it notifies the
   state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
   from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API for
both provider and consumer device driver. To clarify the meaning of
header file and to remove the wrong use-case on consumer device,
this patch separates into extcon.h and extcon-provider.h.

[Description for include/linux/{extcon.h|extcon-provider.h}]
- extcon.h includes the extcon API and data structure for extcon consumer
  device driver. This header file contains the following APIs:
  : Register/unregister the notifier to catch the change of extcon device
  : Get the extcon device instance
  : Get the extcon device name
  : Get the state of each external connector
  : Get the property value of each external connector
  : Get the property capability of each external connector

- extcon-provider.h includes the extcon API and data structure for extcon
  provider device driver. This header file contains the following APIs:
  : Include 'include/linux/extcon.h'
  : Allocate the memory for extcon device instance
  : Register/unregister extcon device
  : Set the state of each external connector
  : Set the property value of each external connector
  : Set the property capability of each external connector

 - A conversion to the dev_get_platdata() API for all MFD drivers.
 
 - A removal of non-DT (legacy) support for the twl6040 driver.

Linus Torvalds aa7054f5a5 Bulk pin control changes for the v3.12 series:
- Refactorings for generic pin config handling in the core.
 
 - Factor out a set of device tree utilities for use in all
   drivers, to parse and allocate maps from the device tree.
 
 - Some fixes to the core such as more nitpicky locking.
 
 - Pushed down config array iteration into the drivers.
   This patch is necessary for drivers that want to iterate
   over configs and pile up a stack of alterations to the
   same register(s), or if the driver wants to take a local
   spinlock when committing the configuration.
 
 - A new driver for the Texas Instruments Palmas PMIC by
   Laxman Dewangan. This is used on the Tegra systems.
 
 - A major cleanup and modernization of the PFC (Super Hitachi
   and ARM SHmobile) pin controller and subdrivers.
 
 - Support for the A20 and A31 sunxi (AllWinner) SoCs.
 
 - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han
   Dan Carpenter, Julia Lawall and Sachin Kamat did an
   excellent job here.

Merge tag 'pinctrl-v3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control changes from Linus Walleij:
 "Here is the bulk of pin control changes for the v3.12 series.  Most of
  the relevant information is in the tag.

  I merged in v3.11-rc7 last week to get rid of a largeish conflict
  within the sunxi (AllWinner) driver in linux-next and fix up the
  non-trivial merge the right way.  That driver had a rather large fix
  adding locking late in the release cycle.

  Overall the bulk changes this time is cleanups and refactorings and
  not much new features, which is nice.

   - Refactorings for generic pin config handling in the core.

   - Factor out a set of device tree utilities for use in all drivers,
     to parse and allocate maps from the device tree.

   - Some fixes to the core such as more nitpicky locking.

   - Pushed down config array iteration into the drivers.

     This patch is necessary for drivers that want to iterate over
     configs and pile up a stack of alterations to the same register(s),
     or if the driver wants to take a local spinlock when committing the
     configuration.

   - A new driver for the Texas Instruments Palmas PMIC by Laxman
     Dewangan.  This is used on the Tegra systems.

   - A major cleanup and modernization of the PFC (Super Hitachi and ARM
     SHmobile) pin controller and subdrivers.

   - Support for the A20 and A31 sunxi (AllWinner) SoCs.

   - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
     Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

The Palma device like TPS65913 have the mode mask which is also
used for enable/disable the rails. The mode bits are defined as
	00: OFF
	01: AUTO
	10: ECO
	11: Forced PWM

and modes are set accordingly as
	REGULATOR_MODE_NORMAL: AUTO
	REGULATOR_MODE_IDLE: ECO
	REGULATOR_MODE_FAST: PWM

Two issue observed:
1. If client calls following sequence:
	regulator_enable(),
	regulator_set_mode(FAST),
	regulator_disable()

	and again the regulator_enable() then the mode is reset
	to NORMAL inplace of keeping the mode as FAST.

	Fixing this by storing the current mode configured by client
	and restoring modes when enable() is called after disable().

2. In following sequence, the regulator get enabled:
	regulator_disable()
	regulator_set_mode(FAST),

	Fixing this by updating new mode in register only if it is
	enabled.

Laxman Dewangan 28d1e8cd67 regulator: palma: add ramp delay support through regulator constraints
Currently Palma regulator driver support the ramp delay
through rail specific platform data.

As regulator framework support the configuration of ramp
delay through regulator constraint, using the framework
method and removing the platform specific data approach.

Laxman Dewangan 17c11a7603 regulator: palmas: add support for LDO8 tracking mode
LDO8 of Palma device like tps65913 support the tracking mode
on which LDO8 track the SMPS45 voltage when SMPS45 is ON
and use the LDO8.VOLTAGE_SEL register when SMPS45 is OFF.

On track mode, the steps of voltage change for LDO8 is 25mV
where in non-tracking mode it is 50mV. Set the steps accordingly.
Number of voltage count is still same for both the cases.

Laxman Dewangan aa07f02793 regulator: palmas: support for external regulator through control outputs
Palmas device have control outputs like REGEN1, REGEN2, REGEN3,
SYSEN1 and SYSEN2. These control outputs can be used for controlling
external voltage switches to enabled/disable voltage outputs.

Add support of these control outputs through regulator framework.

Laxman Dewangan df545d1cd0 mfd: palmas: Provide irq flags through DT/platform data
Currently driver sets the irq type to IRQF_TRIGGER_LOW which is
causing interrupt registration failure in ARM based SoCs as:
[    0.208479] genirq: Setting trigger mode 8 for irq 118 failed (gic_set_type+0x0/0xf0)
[    0.208513] dummy 0-0059: Failed to request IRQ 118: -22

Provide the irq flags through platform data if device is registered
through board file or get the irq type from DT node property in place
of hardcoding the irq flag in driver to support multiple platforms.

Also configure the device to generate the interrupt signal according to
flag type.

Laxman Dewangan 60c185f059 mfd: palmas: Add APIs to access the Palmas' registers
Palmas register set is divided into different blocks (base and offset)
and hence different i2c addresses. The i2c address offsets are derived
from base address of block of registers.

Add inline APIs to access the Palma's registers which takes the base of
register block and register offset. The i2c address offset is  derived
from the base address of register blocks.
