  • 0c4eae665   rtc: convert drivers/rtc/* to use module_platform_driver() ... Browse Code »

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

  • 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.

    This adds support for the RTC provided by the Maxim 8998 chip. This
    driver was tested on a GONI board by using the rtc-test application from
    the Documentation/rtc.txt.
