  • 8ad0f5b68   rtc: ds1672, max6900, max8998: Add MODULE_DEVICE_TABLE ... Browse Code »

    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

    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")

  • 43c523bff   drivers/rtc/rtc-max8998.c: check for pdata presence before dereferencing ... Browse Code »

    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.

  • 5a167f454   Drivers: rtc: remove __dev* attributes. ... Browse Code »

    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.

  • 03cf7c477   rtc: max8998: Initialize drvdata before registering device ... Browse Code »

    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.

  • 337ce5d1c   mfd: Support LP3974 RTC ... Browse Code »

    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.
