    Subject[PATCH V2 00/20] dmaengine/amba-pl08x updates
    Hi Linus,

    This patchset contains patches for ARM's pl08x DMA controller driver.
    Main changes introduced by this patchset are:
    - Formatting fixes
    - Logical Fixes
    - Support for Peripheral as flow controller
    - Support for sg_len to be greater than 1 for slave transfers
    - Schedule tasklet for error interrupts
    - remove pl08x_pre_boundary() routine
    - support for runtime PM
    - etc

    This patchset is tested on SPEAr600 for following tests:
    - memory to memory copy (using drivers/dma/dmatest, upto 16 threads per channel)
    - peripheral to memory and vice versa (Peripheral: JPEG)

    This was rebased on Vinod's slave-dma.git/next, over following patch:

    commit 1ae105aa7416087f2920c35c3cd16831d0d09c9c
    Merge: 02f8c6a 5a42fb9
    Author: Vinod Koul <>
    Date: Wed Jul 27 20:43:21 2011 +0530

    Merge branch 'next' into for-linus-3.0

    Changes Since V1:
    - Dropped many formatting fixes which were added earlier, as they made things
    look even bad.
    - Fixed tabbing issues in PATCH "Add prep_single_byte_llis() routine"
    - Many comments are updated throughout the patchset.
    - Fixed interrupt handler to report spurious interrupt for channels which are
    not used.
    - Clk enabling/disabling done via runtime PM
    - Complete mask of flow controller is not passed from platform data now,
    direction is decided at runtime.
    - pl08x_free_txd() called with locks.
    - Two new patches are added:
    - Rearrange inclusion of header files in ascending order
    - pass (*ptr) to sizeof() instead of (struct xyz)

    Hope i haven't missed any review comments.
