Pointer for Markus's image conversion work. We need this so we can merge all the pretty drm graphs for 4.12. Signed-off-by: Daniel Vetter

drm: Create DEFINE_DRM_GEM_CMA_FOPS and roll it out to drivers

2017-03-14T13:38:34+00:00

Less code ftw. This converts all drivers except the tinydrm helper module. That one needs more work, since it gets the THIS_MODULE reference from tinydrm.ko instead of the actual driver module like it should. Probably needs a similar trick like I used here with generating the entire struct with a macro.

drm: zte: fix static checker warning on variable 'fmt'

drm: zte: use vblank hooks in struct drm_crtc_funcs

2017-02-09T08:13:20+00:00

The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead. The functions are moved around to save forward declaration.

drm: remove drm_vblank_no_hw_counter assignment from driver code

2017-02-07T20:43:55+00:00

Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.

drm: Rely on mode_config data for fb_helper initialization

2017-02-02T18:12:00+00:00

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

ZTE DRM driver updates for 4.11: - Add missing selection of VIDEOMODE_HELPERS in Kconfig, since ZTE DRM driver uses drm_display_mode_to_videomode(). - Enable HDMI audio support through SPDIF interface based on generic hdmi-audio-codec driver. - Enable VOU VL (Video Layer) to support overlay plane with scaling function. - Refine zx_vou driver a bit and then add TV Encoder output device support.
