  • 4053e7499   rtc: s35390a: convert to devm_i2c_new_dummy_device() ... Browse Code »

    I was about to simplify the call to i2c_unregister_device() when I
    realized that converting to devm_i2c_new_dummy_device() will simplify
    the driver a lot. So I took this approach.

  • 21f274327   rtc: s35390a: 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.

  • 3bd32722c   rtc: s35390a: improve irq handling ... Browse Code »

    On some QNAP NAS devices the rtc can wake the machine. Several people
    noticed that once the machine was woken this way it fails to shut down.
    That's because the driver fails to acknowledge the interrupt and so it
    keeps active and restarts the machine immediatly after shutdown. See
    https://bugs.debian.org/794266 for a bug report.

    Doing this correctly requires to interpret the INT2 flag of the first read
    of the STATUS1 register because this bit is cleared by read.

    Note this is not maximally robust though because a pending irq isn't
    detected when the STATUS1 register was already read (and so INT2 is not
    set) but the irq was not disabled. But that is a hardware imposed problem
    that cannot easily be fixed by software.

  • 8e6583f1b   rtc: s35390a: implement reset routine as suggested by the reference ... Browse Code »

    There were two deviations from the reference manual: you have to wait
    half a second when POC is active and you might have to repeat
    initialization when POC or BLD are still set after the sequence.

    Note however that as POC and BLD are cleared by read the driver might
    not be able to detect that a reset is necessary. I don't have a good
    idea how to fix this.

    Additionally report the value read from STATUS1 to the caller. This
    prepares the next patch.

  • f87e904dd   rtc: s35390a: fix reading out alarm ... Browse Code »

    There are several issues fixed in this patch:

    - When alarm isn't enabled, set .enabled to zero instead of returning
    -EINVAL.
    - Ignore how IRQ1 is configured when determining if IRQ2 is on.
    - The three alarm registers have an enable flag which must be
    evaluated.
    - The chip always triggers when the seconds register gets 0.

    Note that the rtc framework however doesn't handle the result correctly
    because it doesn't check wday being initialized and so interprets an
    alarm being set for 10:00 AM in three days as 10:00 AM tomorrow (or
    today if that's not over yet).

  • fbae3fb15   i2c: Remove all i2c_set_clientdata(client, NULL) in drivers ... Browse Code »

    I2C drivers can use the clientdata-pointer to point to private data. As I2C
    devices are not really unregistered, but merely detached from their driver, it
    used to be the drivers obligation to clear this pointer during remove() or a
    failed probe(). As a couple of drivers forgot to do this, it was agreed that it
    was cleaner if the i2c-core does this clearance when appropriate, as there is
    no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
    This feature was added to the core with commit
    e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

    As there is no need anymore to clear the clientdata-pointer, remove all current
    occurrences in the drivers to simplify the code and prevent confusion.

  • 60b129d7b   i2c: Match dummy devices by type ... Browse Code »

    As the old driver_name/type matching scheme is going away soon, change
    the dummy device mechanism to use the new matching scheme.

    This has the downside that dummy i2c clients can no longer choose
    their name, they'll all appear as "dummy" in sysfs and in log
    messages. I don't think it is a problem in practice though, as there
    is little reason to use these i2c clients to log messages.

    Based on earlier work by Jon Smirl and Jochen Friedrich.

    Update most new-style i2c drivers to use standard module aliasing
    instead of the old driver_name/type driver matching scheme. I've
    left the video drivers apart (except for SoC camera drivers) as
    they're a bit more diffcult to deal with, they'll have their own
    patch later.
