    Subject[PATCH v10 0/6] drm: LogiCVC display controller support
    Date
    This series introduces support for the LogiCVC display controller.
    The controller is a bit unusual since it is usually loaded as
    programmable logic on Xilinx FPGAs or Zynq-7000 SoCs.
    More details are presented on the main commit for the driver.

    More information about the controller is available on the dedicated
    web page: https://www.logicbricks.com/Products/logiCVC-ML.aspx

    Note that this driver has rather simple connector management, which was
    not converted to drm_panel_bridge to keep the ability to enable the panel
    at first vblank but also to support DVI.

    Changes since v9:
    - Added common compatibles for major logicvc versions;
    - Add support for logicvc-5;
    - Rebased on latest drm-misc next.

    Changes since v8:
    - Rebased on top of the latest drm-misc-next;
    - Dropped useless phandle-based syscon regmap support;
    - Switched to a single-port graph description;
    - Updated the device-tree schema to the port schema and added a
    description for the port.

    Change since v7:
    - Replaced DRM_INFO/DRM_ERROR/DRM_DEBUG_DRIVER with fashions using drm_device;
    - Fixed yaml binding alignment issue;
    - Renamed logicvc-display name to the generic "display" name;
    - Added patternProperties match for display in the parent mfd binding;
    - Used drm_atomic_get_new_crtc_state when needed;
    - Checked mode in mode_valid instead of atomic_check;
    - Switched to drmm_mode_config_init;
    - Removed useless logicvc_connector_destroy wrapper;
    - Removed useless drm_dev_put calls;
    - Removed atomic_commit_tail that enables the panel and streamlined the logic;
    - Reworked Makefile cosmetics;
    - Fixed checkpatch issues.

    Changes since v6:
    - Updated to the latest DRM internal API changes;
    - Used an enum to index dt properties instead of the name string.

    Changes since v5:
    - Subclass DRM device and use devm_drm_dev_alloc for allocation;
    - Removed call to drm_mode_config_cleanup (done automatically with devm);
    - Some related code cleanups;
    - Bring back not-for-merge patch adding colorkey support.

    Changes since v4:
    - Updated to internal DRM API changes (rebased on drm-misc-next);
    - Added Kconfig dependency on OF;
    - Added MAINTAINERS entry;
    - Used drm_err and dev_err instead of DRM_ERROR where possible;
    - Various cosmetic changes.

    Changes since v3:
    - Rebased on latest drm-misc;
    - Improved event lock wrapping;
    - Added collect tag;
    - Added color-key support patch (not for merge, for reference only).

    Changes since v2:
    - Fixed and slightly improved dt schema.

    Changes since v1:
    - Switched dt bindings documentation to dt schema;
    - Described more possible dt parameters;
    - Added support for the lvds-3bit interface;
    - Added support for grabbing syscon regmap from parent node;
    - Removed layers count property and count layers child nodes instead.
