2016-12-01drm: Make the connector .detect() callback optionalLaurent Pinchart2-14/+0
Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

2016-10-20drm/sun4i: Add compatible strings for A31/A31s display pipelinesChen-Yu Tsai2-0/+4
The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It also has new display enhancement blocks, such as the DRC (Dynamic Range Controller), the DEU (Display Enhancement Unit), and the CMU (Color Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels. The A31s display pipeline is almost the same, just without MIPI DSI. Only the TCON seems to be different, due to the missing mux for MIPI DSI.

The A31 TCON has mux controls for how TCON outputs are routed to the HDMI and MIPI DSI blocks. Since the A31s does not have MIPI DSI, it only has a mux for the HDMI controller input.

The highest 3bits of the 4 layers buffers are all part of the same register.

Lots of drivers don't properly compile without this when CONFIG_FB=n. It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when it's disabled I think it makes sense to add it to drm_fb_helper.h. Long term we probably need to rethink all the logic to unload firmware framebuffer drivers, at least if we want to be able to move away from CONFIG_FB and fbcon. v2: Unfortunately just stubbing out remove_conflicting_framebuffers in drm_fb_helper.h upset gcc about static vs. non-static declarations, so a new wrapper it needs to be.

Suddenly everyone shows up with their trivial patch series! - piles of if (!ptr) check removals from Markus Elfring - more of_node_put fixes from Peter Chen - make fbdev support really optional in all drivers (except vmwgfx), somehow this fell through the cracks when we did all the hard prep work a while ago. Patches from Tobias Jakobi. - leftover patches for the connector reg/unreg cleanup (required that I backmerged drm-next) from Chris - last vgem fence patch from Chris - fix up warnings in the new sphinx gpu docs build - misc other small bits * tag 'topic/drm-misc-2016-07-22' of git://anongit.freedesktop.org/drm-intel: (57 commits) GPU-DRM-Exynos: Delete an unnecessary check before the function call "vunmap" GPU-DRM-sun4i: Delete an unnecessary check before drm_fbdev_cma_hotplug_event() drm/atomic: Delete an unnecessary check before drm_property_unreference_blob() drm/rockchip: analogix_dp: add missing clk_disable_unprepare() on error drm: drm_connector->s/connector_id/index/ for consistency drm/virtio: Fix non static symbol warning drm/arc: Remove redundant dev_err call in arcpgu_load() drm/arc: Fix some sparse warnings drm/vgem: Fix non static symbol warning drm/doc: Spinx leftovers drm/dp-mst: Missing kernel doc drm/dp-mst: Remove tx_down_in_progress drm/doc: Fix missing kerneldoc for drm_dp_helper.c drm: Extract&Document drm_irq.h drm/doc: document all the properties in drm_mode_config drm/drm-kms.rst: Remove unused drm_fourcc.h include directive drm/doc: Add kerneldoc for @index drm: Unexport drm_connector_unregister_all() drm/sun4i: Remove redundant call to drm_connector_unregister_all() drm/ttm: Delete an unnecessary check before the function call "ttm_tt_destroy" ...

Linux 4.7 As requested by Daniel Vetter as the conflicts were getting messy.
2016-07-20GPU-DRM-sun4i: Delete an unnecessary check before drm_fbdev_cma_hotplug_event()Markus Elfring1-2/+1
The drm_fbdev_cma_hotplug_event() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2016-07-19drm/sun4i: Remove redundant call to drm_connector_unregister_all()Chris Wilson1-1/+0
drm_connector_unregister_all() is automatically called by drm_dev_unregister() and so the manual call can be dropped.

Linux 4.7-rc5 The fsl-dcu pull needs -rc3 so go to -rc5 for now.
2016-06-30drm/sun4i: Send vblank event when the CRTC is disabledMaxime Ripard1-0/+8
So far, we were missing to send the vblank event when disabling the CRTC, making us never report the last vblank event. This was causing a time out on the page flip, which should be solved now. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2016-06-30drm/sun4i: Report proper vblankMaxime Ripard1-1/+1
The sun4i display engine doesn't have any vblank counter. Use the proper helper for that. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2016-06-22drm/sun4i: Remove open-coded drm_connector_register_all()Chris Wilson1-34/+0
drm_dev_register() will now register all known connectors, so we no longer have to do so manually.

2016-06-21drm: Don't call drm_dev_set_unique from platform driversDaniel Vetter1-4/+0
Since commit e112e593b215c394c0303dbf0534db0928e87967 Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org> Date: Fri Dec 11 11:20:28 2015 +0100 drm: use dev_name as default unique name in drm_dev_alloc() we're using a reasonable default which should work for everyone. Only mtk, rcar-du and sun4i are affected, and as kms-only drivers without any rendering support no one should ever care about the unique name v2: Rebase on top of mediatek.
