With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.Acked-by: Linus Walleij

Fix section mismatch that is caused by init code calling exit code:
pmic_remove() cannot be marked as __devexit.WARNING: drivers/regulator/tps6524x-regulator.o(.devinit.text+0x205): Section mismatch in reference from the function pmic_probe() to the function .devexit.text:pmic_remove()
The function __devinit pmic_probe() references
a function __devexit pmic_remove().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
pmic_remove() so it may be used outside an exit section.Signed-off-by: Randy Dunlap

The regulator core had suspend-prepare that turns off the regulators
when entering a system-wide suspend. However, it did not have
suspend-finish that pairs with suspend-prepare and the regulator core
has assumed that the regulator devices and their drivers support
autonomous recover at resume.This patch adds regulator_suspend_finish that pairs with the
previously-existed regulator_suspend_prepare. The function
regulator_suspend_finish turns on the regulators that have always_on set
or positive use_count so that we can reset the regulator states
appropriately at resume.In regulator_suspend_finish, if has_full_constraints, it disables
unnecessary regulators.Signed-off-by: MyungJoo Ham

This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD.
In this initial release, selecting voltages or current-limit
and switching on/off the regulators are supported.Controlling voltages for DVS with GPIOs is not implemented fully
and requires more considerations: it controls multiple bucks (selection
of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO
is activated, we lose the ability to control the voltage of a single
buck regulator independently; i.e., contolling a buck affects other two
bucks. Therefore, using the conventional regulator framework directly
might be problematic. However, in this driver, we try to choose
a setting without such side effect of affecting other regulators and
then try to choose a setting with the minimum side effect (the sum of
voltage changes in other regulators).On the other hand, controlling all the three bucks simultenously based
on the voltage set table may help build cpufreq and similar system
more robust; i.e., all the three voltages are consistent every time
without glitches during transition.Signed-off-by: MyungJoo Ham

The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack. In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.Signed-off-by: Andres Salomon

The variable 'val' is a 'unsigned int', so it can never be less than zero.
This fact makes the "val < 0" part of the test done in BUG_ON() in
mc13xxx_regulator_get_voltage() rather pointles since it can never have
any effect.
This patch removes the pointless test.Signed-off-by: Jesper Juhl

The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.Signed-off-by: MyungJoo Ham
