  • a38bb793e   OMAPDSS: fix regression with display sysfs files ... Browse Code »

    omapdss's sysfs directories for displays used to have 'name' file,
    giving the name for the display. This file was later renamed to
    'display_name' to avoid conflicts with i2c sysfs 'name' file. Looks like
    at least xserver-xorg-video-omap3 requires the 'name' file to be
    present.

    To fix the regression, this patch creates new kobjects for each display,
    allowing us to create sysfs directories for the displays. This way we
    have the whole directory for omapdss, and there will be no sysfs file
    clashes with the underlying display device's sysfs files.

    We can thus add the 'name' sysfs file back.

  • 96976c3d9   drm/exynos: Add DECON driver ... Browse Code »

    This patch is based on exynos-drm-next branch of Inki Dae's tree at:
    git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git

    DECON(Display and Enhancement Controller) is the new IP
    in exynos7 SOC for generating video signals using pixel data.

    DECON driver can be used to drive 2 different interfaces on Exynos7:
    DECON-INT(video controller) and DECON-EXT(Mixer for HDMI)

    The existing FIMD driver code was used as a template to create
    DECON driver. Only DECON-INT is supported as of now, and
    DECON-EXT support will be added later.

    The current version of the driver supports video mode displays.

    Changelog v2:
    - Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.

    On some monitors, high resolution modes are not working, exhibiting
    pixel column truncation problems (for example, 1280x1024 displays as
    1280x1022).

    The function ipu_di_adjust_videomode() aims to fix these issues by
    adjusting a passed videomode to IPU restrictions. The function can
    be called from the drm_crtc_helper_funcs->mode_fixup() methods.

  • ef691ff48   OMAPDSS: DT: Get source endpoint by matching reg-id ... Browse Code »

    In omapdss_of_find_source_for_first_ep, we retrieve a source endpoint's DT node,
    and then see what omapdss output has the matching device_node pointer in
    omap_dss_find_output_by_node.

    For all DPI and SDI outputs, the device_node pointer is set as the parent's DSS
    device_node pointer. If the source is one of these outputs, the above method
    won't work.

    To get the correct output for ports within DSS(and in other cases in the future,
    where multiple ports might be under one device), we require additional
    information which is exclusive to the output port.

    We create a new field in omap_dss_device called 'port_num', this provides port
    number of the output port corresponding to this device. When searching for the
    source endpoint in DT, we extract the 'reg' property from the port corresponding
    to the endpoint source. From the list of registered outputs, we pick out that
    output which has both dev->of_node and port_num matching with the device_node
    pointer and 'reg' of the source endpoint node from DT.

    For encoder blocks(the ones which have both an input and output port), we need
    to set the port_num as the 'reg' property for the output port as defined in the
    DT bindings. We set port_num to 1 in the tfp410 and tpd12s015 encoder drivers.

  • 422b67e0b   videomode: provide dummy inline functions for !CONFIG_OF ... Browse Code »

    If CONFIG_OF is disabled but we build any driver that tries to
    use of_get_display_timing, we get this link error:

    ERROR: "of_get_display_timing" [drivers/gpu/drm/rcar-du/rcar-du-drm.ko] undefined!

    This adds an empty inline function as an alternative, to avoid changing
    each driver using this function when we want to build them without
    CONFIG_OF.

    Pull ARM SoC cleanups from Olof Johansson:
    "This merge window brings a good size of cleanups on various platforms.
    Among the bigger ones:

    - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
    have lacked active support for quite a while, and after asking
    around nobody showed interest in keeping them around. If needed,
    they could be resurrected in the future but it's more likely that
    we would prefer reintroduction of them as DT and
    multiplatform-enabled platforms instead.

    - OMAP4 controller code register define diet. They defined a lot of
    registers that were never actually used, etc.

    - Move of some of the Tegra platform code (PMC, APBIO, fuse,
    powergate) to drivers/soc so it can be shared with 64-bit code.
    This also converts them over to traditional driver models where
    possible.

    - Removal of legacy gpio-samsung driver, since the last users have
    been removed (moved to pinctrl)

    Plus a bunch of smaller changes for various platforms that sort of
    dissapear in the diffstat for the above. clps711x cleanups, shmobile
    header file refactoring/moves for multiplatform friendliness, some
    misc cleanups, etc"

    - Uses "lcd_sys" as an IRQ resource and sets relevant IRQ configuration.
    - Sets LCD block configuration for I80 interface.
    - Sets ideal(pixel) clock is 2 times faster than the original one
    to generate frame done IRQ prior to the next TE signal.
    - Implements trigger feature that transfers image data if there is page
    flip request, and implements TE handler to call trigger function.
