  • 92d9d0dfb   i2c: busses: constify i2c_algorithm structures ... Browse Code »

    Declare i2c_algorithm structures as const as they are only stored in the
    algo field of an i2c_adapter structure. This field is of type const, so
    i2c_algorithm structures having this property can be made const too.

  • 32250e4a5   Merge branch 'i2c/for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux ... Browse Code »

    Pull i2c updates from Wolfram Sang:
    "Quite some driver updates:
    - piix4 can now handle multiplexed adapters
    - brcmstb, xlr, eg20t, designware drivers support more SoCs
    - emev2 gained i2c slave support
    - img-scb and rcar got bigger refactoring to remove issues
    - lots of common driver updates

    i2c core changes:
    - new quirk flag when an adapter does not support clock stretching,
    so clients can be configured to avoid that if possible
    - added a helper function to retrieve timing parameters from firmware
    (with rcar being the first user)
    - "multi-master" DT binding added so drivers can adapt to this
    setting (like disabling PM to keep arbitration working)
    - RuntimePM for the logical adapter device is now always enabled by
    the core to ensure propagation from childs to the parent (the HW
    device)
    - new macro builtin_i2c_driver to reduce boilerplate"

  • fcdd5f09c   i2c: st: add include for pinctrl ... Browse Code »

    The driver uses pinctrl directly and thus should include the appropriate
    header. Sort the headers while we are here to have a better view what is
    included and what is not.

  • 52976fa74   i2c: st: Update i2c timings ... Browse Code »

    The i2c timing values specified in the driver are the minimun values
    defined in the I2C specifications. The I2C specification does not
    specify any default or maximum values.

    Some I2C devices are out of spec, such as the HDMI link of the Toshiba
    19AV600 TV, and might not work properly with minimum values.

    This patch adds a 10% margin on all the timings in both Normal and Fast modes.

    Trial and error method have been used to find the minimum margin necessary to
    have the out-of-spec device working, and a security margin has been added.

    This patch adds support to SSC (Synchronous Serial Controller)
    I2C driver. This IP also supports SPI protocol, but this is not
    the aim of this driver.

    This IP is embedded in all ST SoCs for Set-top box platorms, and
    supports I2C Standard and Fast modes.
