    > QUP from version 2.1.1 onwards, supports a new format of i2c command
    > tags.
    > Tag codes instructs the controller to perform a operation like read/write.
    > This new tagging version is required for adding bam dma capabilities.
    > V2 tags supports transfer of more than 256 bytes in a single i2c
    transaction.
    > Also adding bam dma support facilitates transferring each i2c_msg in
    > i2c_msgs without a 'stop' bit in between which is required for some of the
    > clients.

    > [V6] Added review tags and fixed a checkpatch warning in patch 4/6.

    > [V5] Addressed few more comments from Ivan T. Ivanov.
    > Squashed patch 2 and 3 as no point in having only few lines of
    > common code between v1 and v2 tags for increased complexity.
    > Couple of non functional review comments fixes in patch 3, 4.
    > Added a change in patch 4 to have proper transfer completion in
    > a corner case. patch 5, 6 unchanged.
    >
    > [V4] Added a patch to factor out some common code.
    > Removed support for freq > 400KHZ as per comments.
    > Addressed comments from Ivan T. Ivanov to keep the code for
    > V2 support in a separate path.
    > Changed the authorship of V2 tags support patch.
    >
    > [V3] Added support to coalesce each i2c_msg in i2c_msgs for fifo and
    > block mode in Patch 2. Also addressed further code comments.

    Wolfram, Does the first 4 patches looks good to be picked up ?
