Subject[PATCH v12 0/1] [READY FOR MERGE] drm: LogiCVC display controller support
Date
Please consider merging this driver for the next merge window.

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 v11:
- Removed not-for-merge patch;
- Rebased on top of latest drm-misc-next.

Changes since v10:
- Removed common compatibles for major logicvc versions;
- Switched caps detection to use the version registers instead of
the compatible;
- Added support for major version 5 of the unit;
- Used FIELD_GET from bitfield.h and removed local equivalents;
- Updated copyright year;

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.
