  • 68c97b92c   spi: sc18is602: 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.

  • b4e275452   spi: sc18is602: Support multiple devices on a single I2C bus if DT is configured ... Browse Code »

    The driver currently only supports a single device per I2C bus since it uses
    the I2C bus number to set the SPI bus number. This makes it impossible to
    connect more than one chip to a single I2C bus.

    We don't want to use dynamic bus numbers unconditionally since this would
    result in every instantiation getting a different bus number starting with
    65,535 counting down unless devicetree is configured. If devicetree is
    configured, however, the SPI bus number is obtained from devicetree
    data. So we can use dynamic SPI bus numbers in this case.

  • 09e99bca8   spi: sc18is602: Convert to let spi core validate transfer speed ... Browse Code »

    Set master->max_speed_hz and master->min_speed_hz then spi core will handle
    checking transfer speed. So we can remove the same checking in this driver.

    This patch also remove testing if hz is 0 because spi->max_speed_hz will be
    default set to master->min_speed_hz if it was not set. So the transfer speed
    will never set to 0.

  • 589f6a90e   spi: sc18is602: Remove sc18is602_setup() because it is done by spi core ... Browse Code »

    The checking for spi->mode is done in the implementation of spi_setup().
    Calling sc18is602_check_transfer(spi, NULL, 0) is pointless because
    the code is equivent to checking if spi->max_speed_hz is 0.
    Note, sc18is602_check_transfer actually allows spi->max_speed_hz is 0
    if t->speed_hz is set. So return error in sc18is602_setup() when
    spi->max_speed_hz is 0 does not make sense.

  • 463654cec   spi: sc18is602: Convert to use bits_per_word_mask ... Browse Code »

    Since commit 543bb25 "spi: add ability to validate xfer->bits_per_word in SPI
    core", the driver can set bits_per_word_mask for the master then the SPI core
    will reject transfers that attempt to use an unsupported bits_per_word value.
    So we can remove the bits_per_word checking in sc18is602_check_transfer() and
    let SPI core handle the checking.

  • 23061f1eb   spi: Remove duplicate code to set default bits_per_word setting ... Browse Code »

    The implementation in spi_setup() already set spi->bits_per_word = 8 when
    spi->bits_per_word is 0 before calling spi->master->setup.
    So we don't need to do it again in setup() callback.
