  • 189927e71   rtc: pcf8523: set xtal load capacitance from DT ... Browse Code »

    Add support for specifying the xtal load capacitance in the DT node.
    The pcf8523 supports xtal load capacitance of 7pF or 12.5pF.
    If the rtc has the wrong configuration the time will
    drift several hours/week.

    The driver use the default value 12.5pF.

    The DT may specify either 7000fF or 12500fF.
    (The DT uses femto Farad to avoid decimal numbers).
    Other values are warned and the driver uses the default value.

  • bc3bee025   rtc: pcf8523: add support for trimming the RTC oscillator ... Browse Code »

    Add support for reading and writing the RTC offset register, converting
    it to the corresponding parts-per-billion value.

    When setting the drift, the PCF8523 has two modes: one applies the
    adjustment every two hours, the other applies the adjustment every
    minute. We select between these two modes according to which ever
    gives the closest PPB value to the one requested.

  • ede44c908   rtc: pcf8523: properly handle oscillator stop bit ... Browse Code »

    The time and date register of the pcf8223 are undefined after a power
    reset. Properly handle the OS bit and return -EINVAL when that bit is set.

    It is properly removed when setting the time.

    This solves an issue where the time and date may be valid for
    rtc_valid_tm() but is not the current time.

  • fbbf53f70   rtc: pcf8523: refuse to write dates later than 2099 ... Browse Code »

    When the chip increments the YEAR register and it already holds
    bin2bcd(99) it reads as 0 afterwards. With this behaviour the last valid
    day (without trickery) that has a representation is 2099-12-31 23:59:59.
    So refuse to write later dates.

  • f32bc70d5   rtc-pcf8523: add low battery voltage support ... Browse Code »

    Implement reading of the battery voltage low signal for rtc-pcf8523.

    The bit is read-only and cannot be cleared by software, so no
    clear function is implemented.

    Add an RTC driver for PCF8523 chips by NXP Semiconductors. No support is
    currently provided for the alarm and interrupt functions. Only the time
    and date functionality is implemented.
