2013-06-09drm/gma500/cdv: Fix cursor gem obj referencing on cdvPatrik Jakobsson
The internal crtc cursor gem object pointer was never set/updated since it was required to be set in the first place. Fixing this will make the pin/unpin count match and prevent cursor objects from leaking when userspace drops all references to it. Also make sure we drop the gem obj reference on failure. This patch only affects Cedarview chips. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-06-09drm/gma500/cdv: Unpin framebuffer on crtc disablePatrik Jakobsson
The framebuffer needs to be unpinned in the crtc->disable callback because of previous pinning in psb_intel_pipe_set_base(). This will fix a memory leak where the framebuffer was released but not unpinned properly. This patch only affects Cedarview.

2012-08-24gma500/cdv: Fix call to cdv_intel_dp_set_m_nAlan Cox
We should be making this call not praying that the values are right. In addition as noted by Josiah Standing we should be calling this for eDP as well. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-08-24gma500/cdv: Add eDP supportZhao Yakui
Introduce the eDP support into the driver. This has been reworked a bit because kernel driver proper uses encoder/connectors while the legacy Intel driver uses the old output stuff. It also diverges on the backlight handling. The legacy Intel driver adds a panel abstraction based upon the i915 one. It's only really used for backlight bits and we have a perfectly good backlight abstraction which can extend instead.

2012-08-24gma500/cdv: add the bits that don't need the new codeAlan Cox
Based on bits from Yakui <yakui.zhao@intel.com> We can import various little bits of code before we plumb it all in and hopefully this way catch any regressions more easily. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-08-24gma500: Program the DPLL lane based on the selected digitial portZhao Yakui
Based on the spec, the CRT output doesn't use the lane. And the HDMI B output uses the Lane0/1 while the HDMI C output uses the Lane 2/3. But currently it will program all the four lanes for the CRT/HDMI.

2012-08-24gma500: Fix incorrect SR issue when disabling CRTC already in disabled stateZhao Yakui
Currently when trying to call the DPMS off again for one CRTC with DPMS off, it will firstly disable the SR and can't enable it again because of the incorrect check/logic. In such case the self refresh is still disabled although one CRTC pipe is active. This is wrong.

2012-04-27cdv: continue synching up with updated reference codeAlan Cox
In particular clean up the errata handling and correct the crtc masks. We do this a bit differently using our device abstraction for neatness. This doesn't address the ACPI opregion and hotplug plumbing, nor the IRQ related changes that will need. It touches on backlight init but the full backlight support is not in this change set.

2011-12-20drm: Replace pitch with pitches[] in drm_framebufferVille Syrjälä
Otherwise each driver would need to keep the information inside their own framebuffer object structure. Also add offsets[]. BOs on the other hand are driver specific, so those can be kept in driver specific structures.

2011-11-16gma500: Add support for CedarviewAlan Cox
Again this is similar but has some differences so we have a set of plug in support. This does make the driver bigger than is needed in some respects but the tradeoff for maintainability is huge. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
