  • fed9b1861   rtc: remove VLA usage ... Browse Code »

    In preparation to enabling -Wvla, remove VLA and replace it
    with a fixed-length array instead.

    >From a security viewpoint, the use of Variable Length Arrays can be
    a vector for stack overflow attacks. Also, in general, as the code
    evolves it is easy to lose track of how big a VLA can get. Thus, we
    can end up having segfaults that are hard to debug.

    Also, fixed as part of the directive to remove all VLAs from
    the kernel: https://lkml.org/lkml/2018/3/7/621

  • 36138c70e   rtc: bq32k: Add OF device ID table ... Browse Code »

    The driver doesn't have a struct of_device_id table but supported devices
    are registered via Device Trees. This is working on the assumption that a
    I2C device registered via OF will always match a legacy I2C device ID and
    that the MODALIAS reported will always be of the form i2c:.

    But this could change in the future so the correct approach is to have an
    OF device ID table if the devices are registered via OF.

  • 4c466872d   rtc: bq32000: add support to enable disable the trickle charge FET bypass ... Browse Code »

    The bq32000 includes a trickle charge circuit to maintain the charge of the
    backup supply when a super capacitor is used.

    You can enable the charging circuit by setting 'trickle-resistor-ohms',
    additionally you can set TCFE to 1 to bypass the internal diode and boost
    the charge voltage of the backup supply. You might want to enable/disable
    the TCFE switch from userspace (e.g when device is only connected to a
    battery)

    This patch introduces a new sysfs entry to enable and disable this FET
    form userspace.

    Fix register value in bq32000 trickle charging.

    Mike reported that I'm using wrong value in one trickle-charging case,
    and after checking docs, I must admit he's right.

    BQ32000 devices have "trickle chargers". Introduce a code to enable the
    charger, based on device tree.

    Without charger, RTC does not keep time after power off.

  • 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.
