2013-02-22drm: Add some missing forward declarationsThierry Reding1-1/+2
The drm_file and drm_clip_rect structures are used throughout the file but they are never declared nor pulled in through an include. Add forward declarations to make them available.

2013-02-22drm: Move mode tables to drm_edid.cThierry Reding2-781/+746
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.

2013-02-22drm: Remove duplicate drm_mode_cea_vic()Thierry Reding5-29/+12

2013-02-22gma500: Fix n, m1 and m2 clock limits for sdvo and lvdsPatrik Jakobsson1-6/+6
The values of n, m1 and m2 needs to be subtracted by 2 before writing them to the FP register. The dot clock calculation already thinks of these values in register form so we must also specify them as such.

2013-02-21drm/exynos: implement display-mode-check callback in mixer driverRahul Sharma1-0/+26
This patch adds the implementation of check_timing callback in the mixer driver. Based on the mixer version, correct set of restrictions will be exposed by the mixer driver.

2013-02-21drm/exynos: add display-mode-check operation to exynos_mixer_ops structRahul Sharma3-8/+22
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. Both, mixer check-mode and hdmi check-timing callbacks are called one after another and ANDed result is returned back.

2013-02-21drm/exynos: fix wrong pointer access at vm close.YoungJun Cho1-12/+21
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. So this patch uses mutex lock properly to resolve this issue.

2013-02-20drm/nv50-/disp: move DP link training to core and train from supervisorBen Skeggs15-555/+570
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>
