  • ab22e77cd   [media] media framework: rename pads init function to media_entity_pads_init() ... Browse Code »

    With the MC next gen rework, what's left for media_entity_init()
    is to just initialize the PADs. However, certain devices, like
    a FLASH led/light doesn't have any input or output PAD.

    So, there's no reason why calling media_entity_init() would be
    mandatory. Also, despite its name, what this function actually
    does is to initialize the PADs data. So, rename it to
    media_entity_pads_init() in order to reflect that.

    The media entity actual init happens during entity register,
    at media_device_register_entity(). We should move init of
    num_links and num_backlinks to it.

  • 180951071   [media] media: get rid of unused "extra_links" param on media_entity_init() ... Browse Code »

    Currently, media_entity_init() creates an array with the links,
    allocated at init time. It provides a parameter (extra_links)
    that would allocate more links than the current needs, but this
    is not used by any driver.

    As we want to be able to do dynamic link allocation/removal,
    we'll need to change the implementation of the links. So,
    before doing that, let's first remove that extra unused
    parameter, in order to cleanup the interface first.

  • b5dcee225   [media] include/media: split I2C headers from V4L2 core ... Browse Code »

    Currently, include/media is messy, as it contains both the V4L2 core
    headers and some driver-specific headers on the same place. That makes
    harder to identify what core headers should be documented and what
    headers belong to I2C drivers that are included only by bridge/main
    drivers that would require the functions provided by them.

    Let's move those i2c specific files to its own subdirectory.

    The files to move were produced via the following script:
    mkdir include/media/i2c
    (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
    (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
    for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

    And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
    for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
    n=`basename $j`
    git grep -l $n
    done
    done|sort|uniq >files && (
    echo "Handling files..." >&2;
    echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
    (
    cd include/$MAIN_DIR;
    for j in $DIRS; do
    for i in $(ls $j); do
    echo "perl -ne 's,(include [\\\"\\&2;
    echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
    (
    cd include/$MAIN_DIR;
    for j in $DIRS; do
    for i in $(ls $j); do
    echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
    done;
    done;
    echo "cat > a && mv a \$i; done"
    );
    ) >script && . ./script

    Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

  • f7234138f   [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config ... Browse Code »

    If a subdevice pad op is called from a bridge driver, then there is
    no v4l2_subdev_fh struct that can be passed to the subdevice. This
    made it hard to use such subdevs from a bridge driver.

    This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
    pointer in the pad ops. This allows bridge drivers to use the various
    try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
    along to the pad op.

    The v4l2_subdev_get_try_* macros had to be changed because of this, so
    I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
    functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
    'git grep v4l2_subdev_get_try_format' you will actually find the header
    where it is defined.

    One remark regarding the drivers/staging/media/davinci_vpfe patches: the
    *_init_formats() functions assumed that fh could be NULL. However, that's
    not true for this driver, it's always set. This is almost certainly a copy
    and paste from the omap3isp driver. I've updated the code to reflect the
    fact that fh is never NULL.

    In order to have subsytem agnostic media bus format definitions we've
    moved media bus definitions to include/uapi/linux/media-bus-format.h and
    prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.

    Replace all references to the old definitions in i2c drivers.

  • fd9fdb78a   [media] of: move graph helpers from drivers/media/v4l2-core to drivers/of ... Browse Code »

    This patch moves the parsing helpers used to parse connected graphs
    in the device tree, like the video interface bindings documented in
    Documentation/devicetree/bindings/media/video-interfaces.txt, from
    drivers/media/v4l2-core/v4l2-of.c into drivers/of/base.c.

    This allows to reuse the same parser code from outside the V4L2
    framework, most importantly from display drivers.
    The functions v4l2_of_get_next_endpoint, v4l2_of_get_remote_port,
    and v4l2_of_get_remote_port_parent are moved. They are renamed to
    of_graph_get_next_endpoint, of_graph_get_remote_port, and
    of_graph_get_remote_port_parent, respectively.
    Since there are not that many current users yet, switch all of
    them to the new functions right away.
