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
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.
Cheers!
