The backlight 1st update was in the otm8009a_prepare() function for a bad reason: backlight was not working in video mode and the otm8009a_prepare() is in command mode for the init sequence. As the backlight is now fixed (no low-power mode), it is good to put it back in the otm8009a_enable() function, avoiding also image glitches visible on some "slow" devices.

Backlight updates was not working anymore since the good implementation of the DSI low-power mode in the DSI host driver. After a longer analysis, the backlight updates in DSI video mode require the DSI high- speed mode. Note: it is important to keep the DSI low-power mode for the rest of the driver as init sequence, sleep in/out... DSI commands work in low-power mode.

Add device_link from panel device (supplier) to DRM device (consumer) when drm_panel_attach() is called. This patch should protect the master DRM driver if an attached panel driver unbinds while it is in use. The device_link should make sure the DRM device is unbound before the panel driver becomes unavailable. The device_link is removed when drm_panel_detach() is called. The drm_panel_detach() should be called by the consumer DRM driver, not the panel driver, otherwise both drivers are racing to delete the same link.

Remove all drm_panel_detach() calls from all panel drivers and update the kerneldoc for drm_panel_detach(). Setting the connector and drm to NULL when the DRM panel device is going away hardly serves any purpose. Usually the whole memory structure is freed right after the remove call. However, calling the detach function from the master DRM device, and setting the connector pointer to NULL, has the logic of marking the panel again as available for another DRM master to attach. The usual situation would be the same DRM master device binding again.

Added encoding of drm content_type property from drm_connector_state within AVI infoframe in order to properly handle external HDMI TV content-type setting. This requires also manipulationg ITC bit, as stated in HDMI spec. v2: * Moved helper function which attaches content type property to the drm core, as was suggested. Removed redundant connector state initialization. v3: * Removed caps in drm_content_type_enum_list. After some discussion it turned out that HDMI Spec 1.4 was wrongly assuming that IT Content(itc) bit doesn't affect Content type states, however itc bit needs to be manupulated as well. In order to not expose additional property for itc, for sake of simplicity it was decided to bind those together in same "content type" property. v4: * Added it_content checking in intel_digital_connector_atomic_check. Fixed documentation for new content type enum. v5: * Moved patch revision's description to commit messages. v6: * Minor naming fix for the content type enumeration string. v7: * Fix parameter name for documentation and parameter alignment in order not to get warning. Added Content Type description to new HDMI connector properties section. v8: * Thrown away unneeded numbers from HDMI content-type property description.

Maxime Ripard authored
The vc4 HVS uses an internal RGB888 representation of the frames, and will by default expand formats using a lower depth using zeros. This causes an issue when we try to use other compositing software such as pixman that fill the missing bits by repeating the higher significant bits. As such, we can't check the display output in a reliable way by doing a software composition and an hardware one and compare both. To prevent this, force the same behaviour so that we can do such things.

Current DRM layer functions don't parse aspect ratio information while converting a user mode->kernel mode or vice versa. This causes modeset to pick mode with wrong aspect ratio, eventually causing failures in HDMI compliance test cases, due to wrong VIC. This patch adds aspect ratio information in DRM's mode conversion and mode comparision functions, to make sure kernel picks mode with right aspect ratio (as per the VIC). Background: This patch was once reviewed and merged, and later reverted due to lack of DRM cap protection. This is a re-spin of this patch, this time with DRM cap protection, to avoid aspect ratio information, when the client doesn't request for it.

We parse the EDID and add all the modes in the connector's modelist. This adds CEA modes with aspect ratio information too, regardless of whether user space requested this information or not. This patch: -prunes the modes with aspect-ratio information, from the drm_mode_get_connector modelist supplied to the user, if the user-space has not set the aspect ratio DRM client cap. However if such a mode is unique in the list, it is kept in the list, with aspect-ratio flags reset. -prepares a list of exposed modes, which is used to find unique modes if aspect-ratio is not allowed. -adds a new list_head 'exposed_head' in drm_mode_display, to traverse the list of exposed modes.

Instead of straight away pruning such a mode, the mode is retained with aspect ratio bits set to zero, provided it is unique. V4: rebase V5: Addressed review comments from Ville: -used a pointer to store last valid mode. -avoided, modifying of picture_aspect_ratio in kernel mode, instead only flags bits of user mode are reset (if aspect-ratio is not supported). V6: As suggested by Ville, corrected the mode pruning logic and elaborated the mode pruning logic and the assumptions taken. V7: rebase V8: rebase V9: rebase V10: rebase V11: Fixed the issue caused in kms_3d test, and enhanced the pruning logic to correctly identify and prune modes with aspect-ratio, if aspect-ratio cap is not set. V12: As suggested by Ville, added another list_head in drm_mode_display to traverse the list of exposed modes and avoided duplication of modes. V13: Minor modifications, as suggested by Ville. v14: As suggested by Daniel Vetter and Ville Syrjala, corrected the pruning logic to avoid any dependency in the order of mode with aspect-ratio.

If the user-space does not support aspect-ratio, and requests for a modeset with mode having aspect ratio bits set, then the given user-mode must be rejected. Secondly, while preparing a user-mode from kernel mode, the aspect-ratio info must not be given, if aspect-ratio is not supported by the user. This patch: 1. rejects the modes with aspect-ratio info, during modeset, if the user does not support aspect ratio. 2. does not load the aspect-ratio info in user-mode structure, if aspect ratio is not supported. 3. adds helper functions for determining if aspect-ratio is expected in user-mode and for allowing/disallowing the aspect-ratio, if its not expected. Signed-off-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> V3: Addressed review comments from Ville: Do not corrupt the current crtc state by updating aspect-ratio on the fly. V4: rebase V5: As suggested by Ville, rejected the modeset calls for modes with aspect ratio, if the user does not set aspect-ratio cap. V6: Used the helper functions for determining if aspect-ratio is expected in the user-mode. V7: rebase V8: rebase V9: rebase V10: Modified the commit-message V11: rebase V12: Merged the patch for adding aspect-ratio helper functions with this patch. V13: Minor modifications as suggested by Ville. V14: Removed helper functions, as they were used only once in legacy modeset path, as suggested by Daniel Vetter.
