The drivers current default configuration drives the pixel data on rising edge of the pixel clock. However, most display sample data on rising edge... This leads to color shift artefacts visible especially at edges. This patch changes the relevant defines to be useful and actually set the bits, and changes pixel clock polarity to drive the pixel data on falling edge by default. The patch also adds an explicit pixel clock polarity flag to the display introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b") using the new bus_flags field to retain the initial behavior.

Introduce bus_flags to specify display bus properties like signal polarities. This is useful for parallel display buses, e.g. to specify the pixel clock or data enable polarity. Suggested-by:

Don't just free the connector when we get the destroy callback. Drop a reference to it, and set it's mst_port to NULL so no more mst work is done on it. v2: core mst accepts NULLs fine. Cleanup EDID code properly. v3: drop the extra reference we were taking. Reviewed-by:

Take a reference when setting a crtc on a connecter, also take one when duplicating if a crtc is set, and drop one on destroy if a crtc is set. v2: take Daniel Stone's advice and simplify the ref/unref dances, also take care of NULL as connector to state reset. v3: remove need for connector NULL check.

This just takes a reference on the connector when we set a mode in the non-atomic paths. v2: Follow Daniel Stone's suggestions on when to take/drop references. Reviewed-by:

This takes a reference count when fbdev adds the connector, and drops it when it removes the connector. It also drops the now unneeded code to find connectors and remove the from the modeset as they are reference counted. v2: drop references when removing all connectors at end. Reviewed-by:

This uses the previous changes to add reference counts to drm connector objects. v2: move fbdev changes to their own patch. add some kerneldoc Reviewed-by:

Ofc I promise just a few leftovers for drm-misc and somehow it's the biggest pull. But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation. Keeps the udl hack, and qxl is tested by Gerd. * tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel: (47 commits) drm: Fixup locking WARN_ON mistake around gem_object_free_unlocked drm/etnaviv: Use lockless gem BO free callback drm/imx: Use lockless gem BO free callback drm/radeon: Use lockless gem BO free callback drm/amdgpu: Use lockless gem BO free callback drm/gem: support BO freeing without dev->struct_mutex MAINTAINERS: Add myself for the new VC4 (RPi GPU) graphics driver.

Finally all the core gem and a lot of drivers are entirely free of dev->struct_mutex depencies, and we can start to have an entirely lockless unref path. To make sure that no one who touches the core code accidentally breaks existing drivers which still require dev->struct_mutex I've made the might_lock check unconditional. While at it de-inline the ref/unref functions, they've become a bit too big. v2: Make it not leak like a sieve. v3: Review from Lucas: - drop != NULL in pointer checks. - fixup copypasted kerneldoc to actually match the functions. v4: Add __drm_gem_object_unreference as a fastpath helper for drivers who abolished dev->struct_mutex, requested by Chris. v5: Fix silly mistake in drm_gem_object_unreference_unlocked caught by intel-gfx CI - I checked for gem_free_object instead of gem_free_object_unlocked ...

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Summary: - Support for pipeline clock between KMS drivers. . Exynos SoC is required to control clocks across KMS drivers according to Exynos SoC version. So this patch refactos some relevant codes and provides generic solution for it. - Add Exynos5433 SoC support to HDMI parts - HDMI and DECON-TV. - Add HW trigger mode support to CRTC drivers. .
