  • c3544f6f5   rtc: isl1208: Add new style nvmem support to driver ... Browse Code »

    Add support for the RTC's NVRAM using the standard nvmem support that is
    part of the Linux RTC framework.

    This driver already has a sysfs attribute that provides access to the
    RTC's NVRAM as a single 16-bit value. Some chips have more than two
    bytes of NVRAM, so this will not work for them. It's also non-standard.

    This sysfs attribute is left in for backward compatibility, but will only
    be able to read the first two bytes of NVRAM. The nvmem interface will
    allow access to all NVRAM, e.g. eight bytes on the isl1218.

  • 5909b87db   rtc: isl1208: Support more chip variations ... Browse Code »

    Add more support in the driver for dealing with differences in is1208
    compatible chips. Put the 1208, 1209, 1218, and 1219 in the list and
    encode information about nvram size, tamper, and timestamp features.

    This adds support for the isl1209, which has a tamper detect but no
    timestamp feature.

  • ed3c52a07   rtc: isl1208: Introduce driver state struct ... Browse Code »

    This driver has no state of its own, depending entirely on what is in
    the generic rtc device.

    Intoduce a state struct. For now it only contains a pointer to the rtc
    device struct, but future patches will add more data.

  • c8c97a4fb   rtc: isl1208: fix negative digital trim reporting ... Browse Code »

    isl1208_i2c_get_dtr() was returning the dtr value directly, but could
    also return a negative error code. Negative trimming values, e.g. -20,
    would get interpreted as an error code, e.g. -ENOTDIR.

    This patch offsets the dtr value by 100 so it's positive and won't alias
    an error code.

    Also fix check that considered a return value of -1 to be success.

  • 5b9fc795f   rtc: isl1208: Fix unintended clear of SR bits ... Browse Code »

    After successful
    sr = isl1208_i2c_set_regs(client, 0, regs, ISL1208_RTC_SECTION_LEN);
    sr will be 0.
    As a result
    sr = i2c_smbus_write_byte_data(client, ISL1208_REG_SR,
    sr & ~ISL1208_REG_SR_WRTC);
    is equal to
    sr = i2c_smbus_write_byte_data(client, ISL1208_REG_SR, 0);
    which clears all flags in SR.

    Add an additional read of SR, to have value of SR in sr again.

  • 038355040   rtc: isl1208: 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.

  • fa5691131   rtc: remove useless DRV_VERSION ... Browse Code »

    Many drivers are defining a DRV_VERSION. This is often only used for
    MODULE_VERSION and sometimes to print an info message at probe time. This
    is kind of pointless as they are all versionned with the kernel anyway.
    Also the core will print a message when a new rtc is found.

    Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
    bogus threaded irq requests") threaded IRQs without a primary handler
    need to be requested with IRQF_ONESHOT, otherwise the request will fail.

    So pass the IRQF_ONESHOT flag in this case.

    The semantic patch that makes this change is available
    in scripts/coccinelle/misc/irqf_oneshot.cocci

    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.

    This patch allows new-style i2c chip drivers to have alias names using

    point, the old i2c driver binding scheme (driver_name/type) is still
    supported.
