  • a821c4af7   dm: Rename dev_addr..() functions ... Browse Code »

    These support the flat device tree. We want to use the dev_read_..()
    prefix for functions that support both flat tree and live tree. So rename
    the existing functions to avoid confusion.

    In the end we will have:

    1. dev_read_addr...() - works on devices, supports flat/live tree
    2. devfdt_get_addr...() - current functions, flat tree only
    3. of_get_address() etc. - new functions, live tree only

    All drivers will be written to use 1. That function will in turn call
    either 2 or 3 depending on whether the flat or live tree is in use.

    Note this involves changing some dead code - the imx_lpi2c.c file.

  • e160f7d43   dm: core: Replace of_offset with accessor ... Browse Code »

    At present devices use a simple integer offset to record the device tree
    node associated with the device. In preparation for supporting a live
    device tree, which uses a node pointer instead, refactor existing code to
    access this field through an inline function.

    We have standard drivers for panels and backlights which can do most of the
    work for us. Move the tegra20 LCD driver over to use those instead of custom
    code.

    This patch includes device tree changes for the nvidia boards. I have only
    been able to test seaboard. If this patch is applied, these boards will
    also need to be synced with the kernel, and updated to use display-timings:

    - colibri
    - medcom-wide
    - paz00
    - tec

  • 54693cbdc   video: tegra: refuse to bind to disabled dcs ... Browse Code »

    This prevents the following boot-time message on any board where only the
    first DC is in use, yet the DC's DT node is enabled:

    stdio_add_devices: Video device failed (ret=-22)

    (This happens on at least Harmony, Ventana, and likely any other Tegra20
    board with display enabled other than Seaboard).

    The Tegra DC's DT node represents a display controller. It may itself
    drive an integrated RGB display output, or be used by some other display
    controller such as HDMI. For this reason the DC node itself is not
    enabled/disabled in DT; the DC itself is considered a shared resource, not
    the final (board-specific) display output. The node should instantiate a
    display output driver only if the rgb subnode is enabled. Other output
    drivers are free to use the DC if they are enabled and their DT node
    references the DC's DT node. Adapt the Tegra display drivers' bind()
    routine to only bind to the DC's DT node if the RGB subnode is enabled.

    Now that the display driver does the right thing, remove the workaround
    for this issue from Seaboard's DT file.

  • 0f9258228   of: clean up OF_CONTROL ifdef conditionals ... Browse Code »

    We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
    devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
    away the ugly logic in include/fdtdec.h:

    #ifdef CONFIG_OF_CONTROL
    # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
    # define OF_CONTROL 0
    # else
    # define OF_CONTROL 1
    # endif
    #else
    # define OF_CONTROL 0
    #endif

    Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
    CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
    SPL.

    Also, we no longer have to cancel CONFIG_OF_CONTROL in
    include/config_uncmd_spl.h and scripts/Makefile.spl.

    This renames all the Tegra20 pinmux pins and functions so they have a
    prefix which matches the type name.

    The entries in tegra20_pingroups[] are all updated to remove the columns
    which are no longer used.

    All affected code is updated to match.

    lcd_color_fg and lcd_color_bg had to be declared in board specific

    Get rid of the global variables, and use the getter function where
    needed (so far no setter calls are needed).

  • 0c5587549   video: tegra: Update line length to match resolution ... Browse Code »

    Instead of storing the computed line length in a local variable, store
    it in the global lcd_line_length variable to make sure the LCD subsystem
    can properly draw content for the display resolution.

    This probably wasn't noticed yet because the only board where LCD
    support is currently enabled is Seaboard, which runs at a 1366x768
    resolution. As it happens this is the maximum resolution supported and
    also the default that is used to initialize the framebuffer before the
    configuration from DT is available.
