2013-02-22video: Add generic HDMI infoframe helpersThierry Reding
Add generic helpers to pack HDMI infoframes into binary buffers. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
2013-02-22drm: Move mode tables to drm_edid.cThierry Reding
The modes are only used from within drm_edid.c so we move them there to avoid creating duplicates by multiple inclusion of drm_edid_modes.h. As a side-effect we can also get rid of a few variables that keep track of the number of entries in the tables and use ARRAY_SIZE() instead.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next The summary: . Add display mode check operaion to mixer driver - Mixer IP also can put certain restrictions on the proposed display modes and these restrictions need to be considered during mode negotiation, which happens immediately after edid parsing. . Set correct mode for range of resolutions - With this patch, the mixer driver could find the correct mode for the range of resolutions upto 1080 vertical lines. . Support extra resolution for hdmi - This patch programs the core and timing generator registers using the timing data provided in drm_display_mode without hard-coded configurations. So this patch adds additional PHY configs to allow us to support more permissible resolutions and refresh rates. . Add device tree support for g2d - This patch adds just the compatible string for exynos5250 SoC so that with device tree enabling, this driver can be probed. . And bug fixes and code cleanups. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: Add device tree based discovery support for G2D drm/exynos: hdmi: support extra resolutions using drm_display_mode timings drm/exynos: mixer: set correct mode for range of resolutions drm/exynos: implement display-mode-check callback in mixer driver drm/exynos: add display-mode-check operation to exynos_mixer_ops struct drm/exynos: release resources properly when fb creation is failed. drm/exynos: fix wrong pointer access at vm close. drm/exynos: Add missing braces around sizeof drm/exynos: consider exception case to fb handle creation drm/exynos: fix iommu address allocation order

This patch adds the display mode check operation to exynos_mixer_ops in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions on the proposed display modes. These restriction needs to be considered during mode negotiation, which happens immediately after edid parsing.

This patch fixes wrong pointer access issue to filp->f_op and filp->private_data. The exynos_drm_gem_mmap_ioctl() changes filp->f_op and filp->private_data temporarily and restore them to use original ones in exynos_drm_gem_mmap_buffer() but there was no lock between the changing and the restoring so wrong pointer access to filp->f_op and filp->private_data was induced by vm close callback.

2013-02-20drm/nv50-/disp: move DP link training to core and train from supervisorBen Skeggs
We need to be able to do link training for PIOR-connected ANX9805 from the third supervisor handler (due to script ordering in the bios, can't have the "user" call train because some settings are overwritten from the modesetting bios scripts). This moves link training for SOR-connected DP encoders to the second supervisor interrupt, *before* we call the modesetting scripts (yes, different ordering from PIOR is necessary). This is useful since we should now be able to remove some hacks to workaround races between the supervisor and link training paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
