2019-06-11drm/gma500/cdv: Check vbt config bits when detecting lvds panelsPatrik Jakobsson
commit 7c420636860a719049fae9403e2c87804f53bdde upstream. Some machines have an lvds child device in vbt even though a panel is not attached. To make detection more reliable we now also check the lvds config bits available in the vbt.

2016-08-16drm: Remove display_info->min/max_(h|v)maxDaniel Vetter
No one looks at it, only i915/gma500 lvds even bother to fill it out. I guess a very old plan was to use this for filtering modes, but that's already done within the edid parser. v2: Move misplaced hunk to this patch.

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. This issue was detected by using the Coccinelle software.

2014-04-01drm: Replace crtc fb with primary plane fb (v3)Matt Roper
Now that CRTC's have a primary plane, there's no need to track the framebuffer in the CRTC. Replace all references to the CRTC fb with the primary plane's fb. This patch was generated by the Coccinelle semantic patching tool using the following rules: @@ struct drm_crtc C; @@ - (C).fb + C.primary->fb @@ struct drm_crtc *C; @@ - (C)->fb + C->primary->fb v3: Generate patch via coccinelle.

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.
