This patchset reworks the udl driver's modesetting code. Patches #1 to #5 improve the connector code with various updates. Patches #6 to #10 improve the modesetting code. Patch #7 replaces the simple-KMS helpers with the regular atomic helpers. Patch #9 adds DRM hot-unplugging. The driver had some unplugging support via USB functions, the DRM side was probably not prepared yet. Patch #10 changes damage updates to the damage iterator. This minimizes the amount of data to send over USB. Patches #11 to #16 add protocol constants for the various UDL display operations. Tested with X11, console and Weston. v2: * use FIELD_GET macros when programming scanout address (Javier) * improve commit messages (Javier) * drop empty atomic_disable plane helper Thomas Zimmermann (16): drm/udl: Rename struct udl_drm_connector to struct udl_connector drm/udl: Test pixel limit in mode-config's mode-valid function drm/udl: Use USB timeout constant when reading EDID drm/udl: Various improvements to the connector drm/udl: Move connector to modesetting code drm/udl: Remove udl_simple_display_pipe_mode_valid() drm/udl: Convert to atomic-modesetting helpers drm/udl: Simplify modesetting in CRTC's enable function drm/udl: Support DRM hot-unplugging drm/udl: Use damage iterator drm/udl: Move register constants to udl_proto.h drm/udl: Add constants for display-mode registers drm/udl: Add register constants for color depth drm/udl: Add register constants for video locks drm/udl: Add register constants for framebuffer scanout addresses drm/udl: Add constants for commands drivers/gpu/drm/udl/Makefile | 2 +- drivers/gpu/drm/udl/udl_connector.c | 139 ------- drivers/gpu/drm/udl/udl_connector.h | 15 - drivers/gpu/drm/udl/udl_drv.h | 42 +-- drivers/gpu/drm/udl/udl_modeset.c | 563 ++++++++++++++++++---------- drivers/gpu/drm/udl/udl_proto.h | 68 ++++ drivers/gpu/drm/udl/udl_transfer.c | 7 +- 7 files changed, 451 insertions(+), 385 deletions(-) delete mode 100644 drivers/gpu/drm/udl/udl_connector.c delete mode 100644 drivers/gpu/drm/udl/udl_connector.h create mode 100644 drivers/gpu/drm/udl/udl_proto.h -- 2.37.3
