regulator: anatop: Constify anatop_core_rops
anatop_core_rops is not modified and can therefore be made const which
allows the compiler to put it in read-only memory.

regulator: anatop: Lower error message level for -EPROBE_DEFER
devm_regulator_register() could return -EPROBE_DEFER when trying to
get init data and NOT all resources are available at that time, for
this case, error message is better to be present for debug level ONLY.

regulator: anatop: Remove unneeded fields from struct anatop_regulator
These fields are only used in anatop_regulator_probe() so use local
variables instead. The *initdata is not used so can be removed.
The *anatop is renamed to *regmap for better readability.
Use u32 instead of int for the variables used as third argument of
of_property_read_u32().

Javier Martinez Canillas 072e78b12b regulator: of: Add regulator desc param to of_get_regulator_init_data()
The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).

Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.

of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

Remove checking control_reg in [set|get]_voltage_sel and then convert to use
regulator_[set|get]_voltage_sel_regmap for [set|get]_voltage_sel callbacks.

The anatop-reg-offset property is a required property rather than optional
property. So the question is what is the meaning of setting anatop-reg-offset
to 0? If 0 is a valid setting for anatop-reg-offset and it has special meaning,
we had better document it in the binding document. Otherwise, remove the testing
for control_reg in the driver.

No anatop voltage regulator node in the dts files set anatop-reg-offset to 0.
So I think it's safe to remove testing if control_reg is 0.

Since bypass and power gating modes are not configured

For cpufreq example, it takes 13 steps (25 mV for one step) to increase
vddcore from 0.95 V to 1.275 V, and the time of 64 clock cycles at
24 MHz for one step is ~2.67 uS, so the total delay time would be
~34.71 uS.  But the current calculation in the driver gives 39 uS.
Change the formula to have the addition of 1 be the last step, so that
we can get a more precise delay time.  For example above, the new
formula will give 35 uS.

This change removes the use of __devinit, __devexit_p, __devinitdata,

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Linus Torvalds 578f1ef91a MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
 
 - TI LP8788
 - TI OMAP USB TLL
 - Maxim MAX8907
 - SMSC ECE1099
 - Dialog Semiconductor DA9055
 - A simpler syscon driver that allow us to get rid of the anatop one.
 
 Drivers are also gradually getting Device Tree and IRQ domain support.
 
 The following drivers got DT support:
 - palmas, 88pm860x, tc3589x and twl4030-audio
 
 And those ones now use the IRQ domain APIs:
 - 88pm860x, tc3589x, db8500_prcmu
 
 Also some other interesting changes:
 - Intel's ICH LPC now supports Lynx Point
 - TI's twl4030-audio added a GPO child
 - tps6527 enabled its backlight subdevice
 - The twl6030 pwm driver moved to the new PWM subsystem
 
 And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
 ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 "MFD bits for the 3.7 merge window.

  As usual we have a few new drivers:

   - TI LP8788
   - TI OMAP USB TLL
   - Maxim MAX8907
   - SMSC ECE1099
   - Dialog Semiconductor DA9055
   - A simpler syscon driver that allow us to get rid of the anatop one.

  Drivers are also gradually getting Device Tree and IRQ domain support.

  The following drivers got DT support:
   - palmas, 88pm860x, tc3589x and twl4030-audio

  And those ones now use the IRQ domain APIs:
   - 88pm860x, tc3589x, db8500_prcmu

  Also some other interesting changes:
   - Intel's ICH LPC now supports Lynx Point
   - TI's twl4030-audio added a GPO child
   - tps6527 enabled its backlight subdevice
   - The twl6030 pwm driver moved to the new PWM subsystem

  And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
  palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."

Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.

Guys, DON'T REBASE!

We need to do left shift anatop_reg->vol_bit_shift bits for the correct mask.

     ST-E's STAX211, Samsung's MAX77693 and TI's LM3533.

   * Device tree support for the twl6040, tps65910, da9502 and ab8500
