2017-05-23drm/gma500/psb: Actually use VBT mode when it is foundPatrik Jakobsson
With LVDS we were incorrectly picking the pre-programmed mode instead of the prefered mode provided by VBT. Make sure we pick the VBT mode if one is provided. It is likely that the mode read-out code is still wrong but this patch fixes the immediate problem on most machines.

2016-12-01drm: Make the connector .detect() callback optionalLaurent Pinchart
Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

No one looks at it, only i915/gma500 lvds even bother to fill it out.

2016-07-22GPU-DRM-GMA500: Delete unnecessary checks before two function callsMarkus Elfring
The functions pci_dev_put() and psb_intel_i2c_destroy() test whether their argument is NULL and then return immediately. Thus the tests around their calls are not needed.

2014-03-24drm/gma500: add locking to fixed panel edid probingDaniel Vetter
With the recent addition of locking checks in commit 62ff94a5492175759546f8bc61383189d6b49122 Author: Daniel Vetter <daniel.vetter@ffwll.ch> AuthorDate: Thu Jan 23 22:18:47 2014 +0100 drm/crtc-helper: remove LOCKING from kerneldoc drm_add_edid_modes started to WARN about the mode_config.mutex not being held in the lvds and dp initialization code. Now since this is init code locking is fairly redudant if it wouldn't be for the drm core registering sysfs files a bit early. And the locking WARNINGs nicely enforce that indeed all access to the mode lists are properly protected. And a full audit shows that only i915 and gma500 touch the modes lists at init time. Hence I've opted to wrap up this entire mode detection sequence for fixed panels with the mode_config mutex for both lvds and edp outputs.

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.

2012-03-10intel, gma500, lvds: Fix use after free and mem leak in psb_intel_lvds_init()Jesper Juhl
In psb_intel_lvds_init(), if we fail to allocate memory for 'psb_intel_connector' we free the memory we previously allocated for 'psb_intel_encoder', but we then proceed to use that free'd pointer when we do 'psb_intel_encoder->dev_priv = lvds_priv;'. We may also leak the memory we allocated for 'psb_intel_encoder' if we 'goto failed_connector;' and the variable goes out of scope. While I was there anyway, I also removed the pointless 'if (psb_intel_connector)' before freeing it at the 'failed_connector:' label - kfree() deals gracefully with NULL pointers, so it is not needed.

2011-11-16gma500: Add Poulsbo supportAlan Cox
This provides the specific code for Poulsbo, some of which is also used for the later chipsets. We support the GTT, the 2D engine (for console), and the display setup/management. We do not support 3D or the video overlays. In theory enough public info is available to do the video overlay work but that represents a large task. Framebuffer X will run nicely with this but do *NOT* use the VESA X server at the same time as KMS. With a Dell mini 10 things like Xfce4 are nice and usable even when compositing as the CPU has a good path to the memory.
