The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.

The device table is required to load modules based on modaliases.
After adding MODULE_DEVICE_TABLE, below entries will be added to
modules.alias:
alias i2c:ds1672 rtc_ds1672
alias i2c:max6900 rtc_max6900
alias platform:lp3974-rtc rtc_max8998

Pull MFD update from Samuel Ortiz:
"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 0998d0631001 ("device-core: Ensure drvdata = NULL when
no driver is bound")

After the switch to devm_ functions and the removal of
rtc_device_unregister(), the 'remove' function does not do anything.

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound"). Thus, it is not needed to manually
clear the device driver data to NULL.

This patch adds irq domain support for max8998 interrupts.
To keep both non-DT and DT worlds happy, simple domain is used, which is
linear when no explicit IRQ base is specified and legacy, with static
mapping, otherwise.

Currently the driver can crash with a NULL pointer dereference if no
pdata is provided, despite of successful registration of the MFD part.
This patch fixes the problem by adding a NULL check before dereferencing
the pdata pointer.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
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.

Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") uncovered
an issue in a number of RTC drivers, where the drivers call
rtc_device_register before initializing the device or platform drvdata.
This frequently results in null pointer dereferences when the
rtc_device_register immediately makes use of the rtc device, calling
rtc_read_alarm.
The solution is to ensure the drvdata is initialized prior to registering
the rtc device.

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.
