2013-02-21drm/exynos: Add device tree based discovery support for G2DAjay Kumar1-0/+10
This patch adds device tree match table for Exynos G2D controller. Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-02-21drm/exynos: hdmi: support extra resolutions using drm_display_mode timingsSean Paul1-648/+374
This patch programs the core and timing generator registers using the timing data provided in drm_display_mode and not using hard-coded configurations. Additional PHY configs has been added. This allows us to support more permissible resolutions and refresh rates.

2013-02-21drm/exynos: mixer: set correct mode for range of resolutionsRahul Sharma1-4/+4
With this patch, mixer driver find the correct resolution mode for the range of resolutions, upto 1080 vertical lines. Resolution will be categorized to NTSC SD, PAL SD or HD and the correct mode is set to the mixer configuration register.

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. A resolution will be acceptable only if passes the criteria set by mixer and hdmi IPs.

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>
