  • 776bbb97e   video: Kconfig: move drm and fb into separate menus ... Browse Code »
    5

    At the moment the "Device Drivers / Graphics support" kernel config page
    looks rather messy, with DRM and fbdev driver selections on the same
    page, some on the top level Graphics support page, some under their
    respective subsystems.

    If I'm not mistaken, this is caused by the drivers depending on other
    things than DRM or FB, which causes Kconfig to arrange the options in
    not-so-neat manner.

    Both DRM and FB have a main menuconfig option for the whole DRM or FB
    subsystem. Optimally, this would be enough to arrange all DRM and FB
    options under the respective subsystem, but for whatever reason this
    doesn't work reliably.

    This patch adds an explicit submenu for DRM and FB, making it much
    clearer which options are related to FB, and which to DRM.

  • 19757fc84   fbdev: move fbdev core files to separate directory ... Browse Code »
    5

    Instead of having fbdev framework core files at the root fbdev
    directory, mixed with random fbdev device drivers, move the fbdev core
    files to a separate core directory. This makes it much clearer which of
    the files are actually part of the fbdev framework, and which are part
    of device drivers.

  • f7018c213   video: move fbdev to drivers/video/fbdev ... Browse Code »
    18

    The drivers/video directory is a mess. It contains generic video related
    files, directories for backlight, console, linux logo, lots of fbdev
    device drivers, fbdev framework files.

    Make some order into the chaos by creating drivers/video/fbdev
    directory, and move all fbdev related files there.

    No functionality is changed, although I guess it is possible that some
    subtle Makefile build order related issue could be created by this
    patch.

    Avoid colision with regmap's struct reg_field definition by renaming
    omapdss's struct reg_field to dispc_reg_field, and moving it inside
    dispc.c as that's the only place it is used.

  • 0925afc9a   OMAPDSS: fix shared irq handlers ... Browse Code »
    5

    DSS uses shared irq handlers for DISPC and DSI, because on OMAP3, the
    DISPC and DSI share the same irq line.

    However, the irq handlers presume that the hardware is enabled, which,
    in theory, may not be the case with shared irq handlers. So if an
    interrupt happens while the DISPC/DSI is off, the kernel will halt as
    the irq handler tries to access the DISPC/DSI registers.

    In practice that should never happen, as both DSI and DISPC are in the
    same power domain. So if there's an IRQ for one of them, the other is
    also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will
    generate a spurious IRQ, which then causes the problem.

    This patch adds an is_enabled field for both DISPC and DSI, which is
    used to track if the HW is enabled. For DISPC the code is slightly more
    complex, as the users of DISPC can register the interrupt handler, and
    we want to hide the is_enabled handling from the users of DISPC.

    FB driver uses lowlevel controls for LCD powering and contrast changing.
    Since LCD class cannot be used as an optional feature and should be
    compiled for using in the driver, this patch selects LCD_CLASS_DEVICE

    "clk: divider: fix rate calculation for fractional rates" patch (and
    similar for TI specific divider) fixes the clk-divider's rounding. This
    patch updates the DSS driver to round the rates accordingly.

    This fixes the DSS's warnings about clock rate mismatch, and also fixes
    the wrong fclk rate being set.
