2017-02-02	drm: Rely on mode_config data for fb_helper initialization	Gabriel Krisman Bertazi	1	-1/+1
	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. // <smpl> @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; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

2016-12-15	drm: Nuke fb->pixel_format	Ville Syrjälä	1	-1/+1
	Replace uses of fb->pixel_format with fb->format->format. Less duplicated information is a good thing. Note that coccinelle failed to eliminate the "/* fourcc format /" comment from drm_framebuffer.h, so I had to do that part manually. @@ struct drm_framebuffer FB; expression E; @@ drm_helper_mode_fill_fb_struct(...) { ... - FB->pixel_format = E; ... } @@ struct drm_framebuffer FB; expression E; @@ i9xx_get_initial_plane_config(...) { ... - FB->pixel_format = E; ... } @@ struct drm_framebuffer FB; expression E; @@ ironlake_get_initial_plane_config(...) { ... - FB->pixel_format = E; ... } @@ struct drm_framebuffer FB; expression E; @@ skylake_get_initial_plane_config(...) { ... - FB->pixel_format = E; ... } @@ struct drm_framebuffer a; struct drm_framebuffer b; @@ ( - a->pixel_format + a->format->format \| - b.pixel_format + b.format->format ) @@ struct drm_plane_state a; struct drm_plane_state b; @@ ( - a->fb->pixel_format + a->fb->format->format \| - b.fb->pixel_format + b.fb->format->format ) @@ struct drm_crtc CRTC; @@ ( - CRTC->primary->fb->pixel_format + CRTC->primary->fb->format->format \| - CRTC->primary->state->fb->pixel_format + CRTC->primary->state->fb->format->format ) @@ struct drm_mode_set *set; @@ ( - set->fb->pixel_format + set->fb->format->format \| - set->crtc->primary->fb->pixel_format + set->crtc->primary->fb->format->format ) @@ @@ struct drm_framebuffer { ... - uint32_t pixel_format; ... }; v2: Fix commit message (Laurent) Rebase due to earlier removal of many fb->pixel_format uses, including the 'fb->format = drm_format_info(fb->format->format);' snafu v3: Adjusted the semantic patch a bit and regenerated due to code changes Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> (v1) Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Link: http://patchwork.freedesktop.org/patch/msgid/1481751175-18463-1-git-send-email-ville.syrjala@linux.intel.com
2016-12-14	drm: mxsfb: drm_dev_alloc() returns error pointers	Dan Carpenter	1	-2/+2
	We should be checking for IS_ERR() instead of NULL because drm_dev_alloc() returns error pointers.

2016-12-08	drm: mxsfb: Select DRM_PANEL	Marek Vasut	1	-0/+1
	Select DRM_PANEL, since the MXSFB driver depends on it. Otherwise, we get the following error when compiling: drivers/built-in.o: In function `mxsfb_probe': core.c:(.text+0x9ce9c): undefined reference to `drm_panel_attach' core.c:(.text+0x9cff0): undefined reference to `drm_panel_detach' drivers/built-in.o: In function `mxsfb_panel_connector_destroy': core.c:(.text+0x9d614): undefined reference to `drm_panel_detach' drivers/built-in.o: In function `mxsfb_create_output': core.c:(.text+0x9d68c): undefined reference to `of_drm_find_panel' make: *** [Makefile:962: vmlinux] Error 1 Signed-off-by: Marek Vasut <marex@denx.de> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Dave Airlie <airlied@redhat.com> Reported-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-12-06	drm: Add new driver for MXSFB controller	Marek Vasut	7	-0/+1004
	Add new driver for the MXSFB controller found in i.MX23/28/6SX . The MXSFB controller is a simple framebuffer controller with one parallel LCD output. Unlike the MXSFB fbdev driver that is used on these systems now, this driver uses the DRM/KMS framework.
