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 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.
