2019-01-17drm/tinydrm: Use damage helper for dirtyfbNoralf Trønnes
This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty handler. All flushing will now happen in the pipe functions. Also enable the damage plane property for all except repaper which can only do full updates. ili9225: This change made ili9225_init() equal to mipi_dbi_init() so use it. v3: Include vblank header (Sam) ili9225 and st7586 can't use mipi_dbi_enable_flush() (David) v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL (kbuild test robot) Cc: David Lechner <david@lechnology.com> Cc: Eric Anholt <eric@anholt.net> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Tested-by: David Lechner <david@lechnology.com> Reviewed-by: David Lechner <david@lechnology.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190115043643.2364-5-noralf@tronnes.org
2019-01-17drm/tinydrm: Use struct drm_rectNoralf Trønnes
This prepares for the switch to drm_atomic_helper_dirtyfb() in the next patch. The damage helper returns a drm_rect so switch to that everywhere including using a pointer in the dirty functions. This is a non-functional change except for the debug print which looks a bit different.

2019-01-09drm/tinydrm: do not reply on drmP.h from drm_gem_cma_helper.hSam Ravnborg
drmP.h was the only header file in the past and a lot of files rely on that drmP.h defines everything. The goal is to one day to delete drmP.h and as a step towards this it will no longer be included in the headers files in include/drm/ To prepare tinydrm/ for this add dependencies that othwewise was pulled in by drmP.h from drm_gem_cma_helper.h To avoid that tinydrm.h became "include everything", push include files to the individual drivers.

2018-11-20drm/tinydrm: Use DRM_GEM_CMA_VMAP_DRIVER_OPSNoralf Trønnes
The CMA helper now has the functionality to ensure a virtual address on imported buffer so use that. While touching all tinydrm drivers, remove the unnecessary inclusion of drm_fb_helper.h in some drivers.

2018-03-28drm/tinydrm: Make fb_dirty into a lower level hookVille Syrjälä
mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the bowels of the .atomic_enable() hook. That prevents us from taking the plane mutex in fb->dirty() unless we also plumb down the acquire context. Instead it seems simpler to split the fb->dirty() into a tinydrm specific lower level hook that can be called from mipi_dbi_enable_flush() and from a generic higher level tinydrm_fb_dirty() helper. As we don't have a tinydrm specific vfuncs table we'll just stick it into tinydrm_device directly for now. v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf) Cc: "Noralf Trønnes" <noralf@tronnes.org> Cc: David Lechner <david@lechnology.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20180323153509.15287-1-ville.syrjala@linux.intel.com Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Tested-by: Noralf Trønnes <noralf@tronnes.org>

Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly. Remove todo entry.
