  • dfc657b13   drivers/rtc/rtc-ds1302.c: handle write protection ... Browse Code »

    This chip has a control register and can prevent altering saved clock.
    Without this patch we could have:

    (arm)root@pac14:~# date
    Tue May 21 03:08:27 MSK 2013
    (arm)root@pac14:~# /etc/init.d/hwclock.sh show
    Tue May 21 11:13:58 2013 -0.067322 seconds
    (arm)root@pac14:~# /etc/init.d/hwclock.sh stop
    [info] Saving the system clock.
    [info] Hardware Clock updated to Tue May 21 03:09:01 MSK 2013.
    (arm)root@pac14:~# /etc/init.d/hwclock.sh show
    Tue May 21 11:14:15 2013 -0.624272 seconds

    The patch enables write access to rtc before the driver tries to write
    time and re-disables when time data is written.

    After the switch to devm_ functions and the removal of
    rtc_device_unregister(), the 'remove' function does not do anything.
    Delete it.

  • 844b8a685   rtc: rtc-ds1302: remove unnecessary platform_set_drvdata() ... Browse Code »

    The driver core clears the driver data to NULL after device_release or
    on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
    = NULL when no driver is bound"). Thus, it is not needed to manually
    clear the device driver data to NULL.

  • 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.

  • 72cc8e51c   rtc-ds1302: add some abstraction for new platform support ... Browse Code »

    The current ds1302 driver (or at least the one that lives in /drivers/rtc)
    seems to be designed for memory mapped devices only. This make it quite
    hard to add support for GPIO-based implementations (as this is the case
    for the upcoming Arcom Vulcan).

    This patch moves the direct register access to inline functions with
    explicit names. Still not as good as a proper platform driver, but at
    least neater.

  • b74d2caa6   rtc: fix driver data issues in several rtc drivers ... Browse Code »

    Herton Ronaldo Krzesinski recently raised up, and fixed, an issue with the
    rtc_cmos driver, which was referring to an inconsistent driver data.

    This patch ensures that driver data registration happens before
    rtc_device_register().

  • 739d340db   rtc: ds1302 rtc support ... Browse Code »

    This adds a basic ds1302 RTC driver, which is basically a cleanup and move
    of the in-tree SH SecureEdge5410 code (which is currently located in
    arch/sh/board/snapgear/rtc.c) to drivers/rtc.

    This aims to be a building block that the M32R and CRIS code can be worked
    on top of, so we can get rid of drivers/char/ds1302.c and
    arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is
    needed for this.
