3aa78e0cb5 For the 3.11 merge we only have one new MFD driver for the Kontron PLD.
But we also have:
 
 - Support for the TPS659038 PMIC from the palmas driver.
 
 - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver.
 
 - RTL8411B support from the rtsx driver.
 
 - More DT support for the Arizona, max8998, twl4030-power and the
   ti_am335x_tsadc drivers.
 
 - The SSBI driver move under MFD.
 
 - A conversion to the devm_* API for most of the MFD drivers.
 
 - The twl4030-power got split from twl-core into its own module.
 
 - A major ti_am335x_adc cleanup, leading to a proper DT support.
 
 - Our regular arizona and wm* updates and cleanups from the Wolfson
   folks.
 
 - A better error handling and initialization, and a regulator subdevice
   addition for the 88pm80x driver.
 
 - A bulk platform_set_drvdata() call removal that's no longer need since
   commit 0998d063.

This patch makes driver to use uV/us as units of ramp_delay. It makes driver
in compliance with regulator framework and make ramp rate precise.

This patch also sets default ramp rate in regulator descriptor which can be
used in case if case ramp rate is not set in regulator constraints.

ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

8c7e7ddf31 regulator: max77693: Remove NULL test for rmatch[i].init_data
The implementation in of_regulator_match() already ensures match->init_data is
not NULL for all matched cases if the return value of of_regulator_match() > 0.

Thus remove NULL test for rmatch[i].init_data.

This patch also fixes the condition for loop iteration.
The for loop should iterate "matched" times rather than ARRAY_SIZE(regulators)
because we only allocate "matched" number of entries for rdata.
Though in most cases, "matched" == ARRAY_SIZE(regulators).

42dc30231b regulator: max8973: initial DT support
This patch adds primitive DT support to the max8973 regulator driver. None
of the configuration parameters, supported in the platform data are yet
available in DT, therefore no configuration is performed if booting with
no platform data. This means, that DT instantiation can only be used on
boards, where no run-time configuration of the chip is required. In such
cases the driver can be used to scale its output voltage. In the future
support for configuration parameters should be added.

Currently the max8973 regulator driver uses a single static struct of
regulator operations for all chip instances, but can overwrite some of its
members depending on configuration. This will affect all other MAX8973
instances on the system. This patch fixes this bug by allocating a separate

The TWL6025 was never released beyond sample form and was replaced by
the PhoenixLite range of chips - TWL6032. Change the references to
reference the TWL6032 class and name the registers to twl6032 in line with
an actual released chip name to avoid confusion.

Currently there are no users of TWL6025 in the code.

While at it, remove the error message as devm_ioremap_resource prints a similar

Commit "i2c: core: make it possible to match a pure device tree driver"
changed semantics of the i2c probing for device tree devices.
Device tree probed devices now get a NULL i2c_device_id pointer.
This caused kernel panics due to NULL dereference.

ce6f5ea3a7 regulator: ab8500: Provide supply names for the AUX regulators
On some platforms the AUX[1|2|3] regulators are supplied voltage by
a separate regulator. For example on Snowball these are provided by
the EXT3. If we list them here, we can supply voltage to them by
simply listing them in as a consumer of EXT3 in the Snowball case.

5a49b4a527 regulator: ab8500-ext: Register as a device in its own right
Some platforms don't support the AB8500 external regulators, so instead
of having a list of is_<platform>() calls prior to calling
ab8500_ext_regulator_init() from ab8500_regulator_probe(), we can only
register as a platform device on platforms which require them. It means
we also have more control over them when booting with Device Tree.

33fb880249 regulator: ab8500-ext: Provide a set_voltage call-back operation
When registering regulators which have a single voltage through Device
Tree, the framework insists that the specified voltage is actually set.
Well in order to do that we need to provide this call-back, where we
check that the value is sane and return without error. Not that the
selector isn't populated, but in our case list_voltage doesn't actually
use it, so we're good.

This patch changes the order in which the AB8500 regulator drivers are
registered and subsequently probed. It saves a lot of -EPROBE_DEFEER
nonsense and bootlog noise, as some AB8500 core regulators depend on
the external ones for supply voltage.

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.

This patch removes the unneeded include of linux/delay.h in regulator drivers.
