Subject: [PATCH v9 0/4] 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
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.
