This patch series adds virtual-plane support to omapdrm driver to allow the use of display wider than 2048 pixels. In order to do so we introduce the concept of hw_overlay which can then be dynamically allocated to a plane. When the requested output width exceed what be supported by one overlay a second is then allocated if possible to handle display wider then 2048. This series replaces an earlier series which was DT based and using statically allocated resources. This implementation is inspired from the work done in msm/disp/mdp5 driver. Benoit Parrot (8): drm/omap: Add ability to check if requested plane modes can be supported drm/omap: Add ovl checking funcs to dispc_ops drm/omap: introduce omap_hw_overlay drm/omap: omap_plane: subclass drm_plane_state drm/omap: Add global state as a private atomic object drm/omap: dynamically assign hw overlays to planes drm/omap: add plane_atomic_print_state support drm/omap: Add a 'right overlay' to plane state drivers/gpu/drm/omapdrm/Makefile | 1 + drivers/gpu/drm/omapdrm/dss/dispc.c | 32 +++ drivers/gpu/drm/omapdrm/dss/omapdss.h | 6 + drivers/gpu/drm/omapdrm/omap_drv.c | 196 ++++++++++++++++- drivers/gpu/drm/omapdrm/omap_drv.h | 30 +++ drivers/gpu/drm/omapdrm/omap_fb.c | 33 ++- drivers/gpu/drm/omapdrm/omap_fb.h | 4 +- drivers/gpu/drm/omapdrm/omap_overlay.c | 257 ++++++++++++++++++++++ drivers/gpu/drm/omapdrm/omap_overlay.h | 41 ++++ drivers/gpu/drm/omapdrm/omap_plane.c | 374 ++++++++++++++++++++++++++++----- drivers/gpu/drm/omapdrm/omap_plane.h | 1 + 11 files changed, 922 insertions(+), 53 deletions(-) create mode 100644 drivers/gpu/drm/omapdrm/omap_overlay.c create mode 100644 drivers/gpu/drm/omapdrm/omap_overlay.h
