2013-04-26drm/edid: Check both 60Hz and 59.94Hz when looking for a CEA modeVille Syrjälä1-3/+24
drm_match_cea_mode() should be able to match both the 60Hz version, and the 59.94Hz version of modes. We only store one pixel clock value per mode in edid_cea_modes, so the other value must be calculated. Depending on the mode, edid_cea_modes contains the pixel clock for either the 60Hz version or the 59.94Hz version, so a bit of care is needed so that the calculation produces the correct result.

2013-04-26drm/edid: Populate vrefresh for CEA modesVille Syrjälä1-64/+129
Well have use for the vrefresh information of CEA modes later. Just populate the information into the table to avoid having to calculate it. I'm too lazy to check if someone relies on newly allocated CEA modes having 0 vrefresh, so just clear vrefresh back to 0 when adding the mode to the connector's modelist.

2013-04-26drm/shmobile: Fix race condition between page flip request and handlerLaurent Pinchart1-1/+1
The page flip handler stores the page flip event pointer and then calls drm_vblank_get() to enable the vblank interrupt. Due to the vblank off delay, the vblank interrupt can be enabled in the hardware at that point, even if the vblank reference count is equal to 0. If a vblank interrupt is triggered between storing the event pointer and calling drm_vblank_get(), the page flip completion handler will process the event and call drm_vblank_put() with a reference count equal to 0. This will result in a BUG_ON. Fix the race condition by calling drm_vblank_get() before storing the event pointer.

The tilcdc driver fails to be built as a module because of extraneous MODULE_DEVICE_TABLE entries: drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here Since the entire point of these entries is to make the module autoload when one of the devices is present, it's enough to keep the one entry for "ti,am33xx-tilcdc", which should always be there if any of the others are.

2013-04-25drm/gma500: fix backlight hotkeys behaviour on netbooksAnisse Astier1-1/+1
Backlight hotkeys weren't working before on certain cedartrail laptops. The source of this problem is that the hotkeys' ASLE opregion interrupts were simply ignored. Driver seemed to expect the interrupt to be associated with a pipe, but it wasn't. Accepting the ASLE interrupt without an associated pipe event flag fixes the issue, the backlight code is called when needed, making the brightness keys work properly.

into drm-next drm/tegra: Changes for v3.10-rc1 The bulk of this pull-request is the host1x series that has been in the works for a few months. The current implementation looks good and has been tested by several independent parties. So far no issues have been found. To be on the safe side, the new Tegra-specific DRM IOCTLs depend on staging in order to give some amount of flexibility to change them just in case. The plan is to remove that dependency once more userspace exists to verify the adequacy of the IOCTLs. Currently only the 2D engine is supported, but patches are in the works to enable 3D support on top of this framework as well. Various bits of open-source userspace exist to test the 2D and 3D support[0]. This is still a bit immature but it allows to verify that the kernel interfaces work properly. To round things off there are two smaller cleanup patches, one of them adding a new pixel format and the other removing a redundent Kconfig dependency.
