    Using result = (value + divisor/2) / divisor is rounding values up and only
    works well for positive values. Instead use DIV_ROUND_CLOSEST which does
    the correct thing.

    Also remove pcf2123_delay_trec. This claimed to add a 30ns delay to SPI
    writes, but I could not see any reference to this requirement in the
    datasheet. Closest thing I could find to a requirement are timings for the
    SPI chip enable line, which cannot be controlled by this driver (the ndelay
    came after the call to spi_write_then_read, which means it would sleep
    after CE has already gone inactive). Things seem to work fine without it.

  • fa5691131   rtc: remove useless DRV_VERSION ... Browse Code »

    Many drivers are defining a DRV_VERSION. This is often only used for
    MODULE_VERSION and sometimes to print an info message at probe time. This
    is kind of pointless as they are all versionned with the kernel anyway.
    Also the core will print a message when a new rtc is found.

  • f07fa9242   rtc: pcf2123: avoid resetting the clock if possible ... Browse Code »

    pcf2123 data sheet recommends a software reset when the chip
    is first powered on. This change avoids resetting the chip
    every time the driver is loaded, which has some negative effects.

    There are several registers including a clock rate adjustment that really
    should survive a reload of the driver (or reboot).

    In addition, stopping and restarting the clock to verify the chip is
    there is not a good thing once the time is set.

    According to the data sheet, the seconds register has a 1 in
    the high bit when the voltage has gotten low. We check for this
    condition, as well as whether the time retrieved from the chip is
    valid. We reset the rtc only if the time is not reliable and valid.
    This is sufficient for checking for the presence of the chip,
    as either all zeros or all 0xff will result in an invalid time/date

  • 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.

  • 6c3fb5579   drivers/rtc/: remove redundant spi driver bus initialization ... Browse Code »

    In ancient times it was necessary to manually initialize the bus field of
    an spi_driver to spi_bus_type. These days this is done in
    spi_driver_register(), so we can drop the manual assignment.

    The patch was generated using the following coccinelle semantic patch:
    //
    @@
    identifier _driver;
    @@
    struct spi_driver _driver = {
    .driver = {
    - .bus = &spi_bus_type,
    },
    };
