* drm/gma500: Increase max resolution for mode settingPatrik Jakobsson2013-04-25
| | | | | | | | By having a higher max resolution we can now set up a virtual framebuffer that spans several monitors. 4096 should be ok since we're gen 3 or higher and should be enough for most dual head setups. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
* drm/gma500: fix backlight hotkeys behaviour on netbooksAnisse Astier2013-04-25
| | | | | | | | | | | | | | | | | | | | 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.

* drm/gma500: Check connector status before restoring sdvoPatrik Jakobsson2013-04-15
| | | | | | | | | | | | | | | | | | | This patch fixes a bug introduced by: commit 749387dc8d8270b279f27a0a794cdf4f4a4aa774 Author: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Date: Sun Apr 7 16:35:50 2013 +0200 drm/gma500: Fix hibernation problems on sdvo encoders The bug is triggered when we do a mode set on a sdvo encoder with all connectors in the disconnected state. A crtc is considered enabled by drm even though all of its connectors are disconnected. Work around this by adding a check in our sdvo restore function. Also remove the unneeded dpms on. Prepare and Commit will take care of that. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
* gma500:fix build failure for 3.9-rc5Xiong Zhou2013-04-10
| | | | | | | | | | | | | | | | | | Last version of this patch is not clear enough and X86 duplicated. This patch fixes build failure of v3.9-rc5 and rc6. When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure. GMA5/600 needs acpi_video just like nouveau. And some tab type fix by the way.

| * | drm/exynos: fix wrong pointer access at vm close.YoungJun Cho2013-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
