    A component master may have both OF based and non-OF based components to be
    bound with. This patch adds a helper drm_of_component_probe_with_match()
    similar to drm_of_component_probe() so that the new helper may get an
    additional provided match pointer(contains match entries for non-OF based
    components) to support this case.

  • 528d06d41   drm: of: Fix linking when CONFIG_OF is not set ... Browse Code »

    The new helper drm_of_lvds_get_dual_link_pixel_order() introduced in
    commit 6529007522de has a fallback stub when CONFIG_OF is not set, but
    the stub is declared in drm_of.h without a static inline. This causes
    multiple definitions of the function to be linked when the CONFIG_OF
    option isn't set. Fix it by making the stub static inline.

    An LVDS dual-link connection is made of two links, with even
    pixels transitting on one link, and odd pixels on the other
    link. The device tree can be used to fully describe dual-link
    LVDS connections between encoders and bridges/panels.
    The sink of an LVDS dual-link connection is made of two ports,
    the corresponding OF graph port nodes can be marked
    with either dual-lvds-even-pixels or dual-lvds-odd-pixels,
    and that fully describes an LVDS dual-link connection,
    including pixel order.

    drm_of_lvds_get_dual_link_pixel_order is a new helper
    added by this patch, given the source port nodes it
    returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source
    port nodes belong to an LVDS dual-link connection, with even
    pixels expected to be generated from the first port, and odd
    pixels expected to be generated from the second port.
    If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS,
    odd pixels are expected to be generated from the first port,
    and even pixels from the other port.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

    Core drm shouldn't depend on anything in drm-kms-helper, or the drm

    This function is the pendant of drm_of_find_panel_or_bridge()
    to remove a previously allocated panel_bridge.
    Given a specific port and endpoint it remove the panel bridge.
    Since drm_panel_bridge_remove() will check that bridge parameter
    is not NULL and is a real drm_panel_bridge and no a simple bridge
    it is safe to call it directly.

    Many drivers have a common pattern of searching the OF graph for either an
    attached panel or bridge and then finding the DRM struct for the panel
    or bridge. Also, most drivers need to handle deferred probing when the
    DRM device is not yet instantiated. Create a common function,
    drm_of_find_panel_or_bridge, to find the connected node and the
    associated DRM panel or bridge device.
