Subject: [PATCH v6 0/3] drm: LogiCVC display controller support

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!
