  • d0ab4a4d5   rtc/hctosys: only claim the RTC provided the system time if it did ... Browse Code »

    Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys
    contains a 1 (meaning "This rtc was used to initialize the system clock")
    even if reading the time at bootup failed.

    Moreover change error handling in rtc_hctosys() to use goto and so reduce
    the indention level.

  • 779d20892   rtc_hctosys expects RTCs in UTC (doc) ... Browse Code »

    The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local
    time (e.g. PST). Say so in Kconfig and in the kernel message.

    (Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's
    not worth going into here. Goofing timezones means clocks are wrong by many
    hours; the POSIX-v-UTC differences just cost seconds.)

    This patch removes class_device from the programming interface that the RTC
    framework exposes to the rest of the kernel. Now an rtc_device is passed,
    which is more type-safe and streamlines all the relevant code.

  • 0c86edc0d   [PATCH] RTC subsystem: class ... Browse Code »

    Add the basic RTC subsystem infrastructure to the kernel.

    rtc/class.c - registration facilities for RTC drivers
    rtc/interface.c - kernel/rtc interface functions
    rtc/hctosys.c - snippet of code that copies hw clock to sw clock
    at bootup, if configured to do so.
