  • 395cf9691   doc: fix broken references ... Browse Code »

    There are numerous broken references to Documentation files (in other
    Documentation files, in comments, etc.). These broken references are
    caused by typo's in the references, and by renames or removals of the
    Documentation files. Some broken references are simply odd.

    Fix these broken references, sometimes by dropping the irrelevant text
    they were part of.

  • 8348c259d   arm/pxa2xx: reorgazine SSP and SPI header files ... Browse Code »

    The PXA-SPI driver relies on some files / defines which are arm specific
    and are within the ARM tree. The CE4100 SoC which is x86 has also the
    SPI core.
    This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
    include/linux where the CE4100 can access them.

    This move got verified by building the following defconfigs:
    cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
    imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
    raumfeld_defconfig magician_defconfig

  • f1f640a9c   pxa2xx_spi: fix chip_info defaults and documentation. ... Browse Code »

    Make the chip info structure data optional by providing reasonable
    defaults. Improve corresponding documentation, and highlight the drawback
    of not providing explicit chipselect control.

    DMA can determine appropriate dma_burst_size and thresholds automatically
    so use DMA even if dma_burst_size is not specified.

  • 96de0e252   Convert files to UTF-8 and some cleanups ... Browse Code »

    * Convert files to UTF-8.

    * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

    * Correct town names (Goettingen -> Göttingen)

    * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

  • 7053acbd7   [ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX ... Browse Code »

    This patch removes the unnecessary bit number from CKENnn_XXXX
    definitions for PXA, so that

    CKEN0_PWM0 --> CKEN_PWM0
    CKEN1_PWM1 --> CKEN_PWM1
    ...
    CKEN24_CAMERA --> CKEN_CAMERA

    The reasons for the change of these defitions are:

    1. they do not scale - they are currently valid for pxa2xx, but
    definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
    instead of bit 24

    2. they are unnecessary - the peripheral name within the definition
    has already announced its usage, we don't need those bit numbers
    to know which peripheral we are going to enable/disable clock for

    3. they are inconvenient - think about this: a driver programmer
    for pxa has to remember which bit in the CKEN register to turn
    on/off

    Another change in the patch is to make the definitions equal to its
    clock bit index, so that

    #define CKEN_CAMERA (24)

    instead of

    #define CKEN_CAMERA (1 << 24)

    this change, however, will add a run-time bit shift operation in
    pxa_set_cken(), but the benefit of this change is that it scales
    when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
    and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
    bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
    and so that pxa_set_cken() need minimum change to adapt to that.

  • 8d94cc50a   [PATCH] spi: stabilize PIO mode transfers on PXA2xx systems ... Browse Code »

    Stabilize PIO mode transfers against a range of word sizes and FIFO
    thresholds and fixes word size setup/override issues.

    1) 16 and 32 bit DMA/PIO transfers broken due to timing differences.
    2) Potential for bad transfer counts due to transfer size assumptions.
    3) Setup function broken is multiple ways.
    4) Per transfer bit_per_word changes break DMA setup in pump_tranfers.
    5) False positive timeout are not errors.
    6) Changes in pxa2xx_spi_chip not effective in calls to setup.
    7) Timeout scaling wrong for PXA255 NSSP.
    8) Driver leaks memory while busy during unloading.

    Known issues:

    SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled.

    Testing:

    This patch has been test against the "random length, random bits/word,
    random data (verified on loopback) and stepped baud rate by octaves
    (3.6MHz to 115kHz)" test. It is robust in PIO mode, using any
    combination of tx and rx thresholds, and also in DMA mode (which
    internally computes the thresholds).

    Much thanks to Ned Forrester for exhaustive reviews, fixes and testing.
    The driver is substantially better for his efforts.

  • e0c9905e8   [PATCH] SPI: add PXA2xx SSP SPI Driver ... Browse Code »

    This driver turns a PXA2xx synchronous serial port (SSP) into a SPI master
    controller (see Documentation/spi/spi_summary). The driver has the following
    features:

    - Support for any PXA2xx SSP
    - SSP PIO and SSP DMA data transfers.
    - External and Internal (SSPFRM) chip selects.
    - Per slave device (chip) configuration.
    - Full suspend, freeze, resume support.
