Merge tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

2013-07-10T18:10:27+00:00

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")

drivers/rtc/rtc-max8998.c: remove empty function

2013-07-03T23:07:53+00:00

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

rtc: rtc-max8998: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:51+00:00

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.

mfd: max8998: Add support for Device Tree

mfd: max8998: Add irq domain support

2013-06-30T21:29:44+00:00

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.

drivers/rtc/rtc-max8998.c: check for pdata presence before dereferencing

2013-05-24T23:22:53+00:00

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.

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02+00:00

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.

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53+00:00

This patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

rtc: max8998: Initialize drvdata before registering device

2011-05-07T01:02:02+00:00

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.
