Add support for generic electronic privacy screen properties, that can be added by systems that have an integrated EPS. Changes in v2 (Hans de Goede) - Create 2 properties, "privacy-screen sw-state" and "privacy-screen hw-state", to deal with devices where the OS might be locked out of making state changes - Write kerneldoc explaining how the 2 properties work together, what happens when changes to the state are made outside of the DRM code's control, etc. Changes in v3 (Hans de Goede) - Some small tweaks to the kerneldoc describing the 2 properties Changes in v4 (Hans de Goede) - Change the "Enabled, locked" and "Disabled, locked" hw-state enum value names to "Enabled-locked" and "Disabled-locked". The xrandr command shows all possible enum values separated by commas in its output, so having a comma in an enum name is not a good idea. - Do not add a privacy_screen_hw_state member to drm_connector_state since this property is immutable its value must be directly stored in the obj->properties->values array Signed-off-by:

If drm_modeset_lock() returns -EDEADLK, the caller is supposed to drop all currently held locks using drm_modeset_backoff(). Failing to do so will result in warnings and backtraces on the paths trying to lock a contended lock. Add support for optionally printing the backtrace on the path that hit the deadlock and didn't gracefully handle the situation. For example, the patch [1] inadvertently dropped the return value check and error return on replacing calc_watermark_data() with intel_compute_global_watermarks(). The backtraces on the subsequent locking paths hitting WARN_ON(ctx->contended) were unhelpful, but adding the backtrace to the deadlock path produced this helpful printout: <7> [98.002465] drm_modeset_lock attempting to lock a contended lock without backoff: drm_modeset_lock+0x107/0x130 drm_atomic_get_plane_state+0x76/0x150 skl_compute_wm+0x251d/0x2b20 [i915] intel_atomic_check+0x1942/0x29e0 [i915] drm_atomic_check_only+0x554/0x910 drm_atomic_nonblocking_commit+0xe/0x50 drm_mode_atomic_ioctl+0x8c2/0xab0 drm_ioctl_kernel+0xac/0x140 Add new CONFIG_DRM_DEBUG_MODESET_LOCK to enable modeset lock debugging with stack depot and trace.

Components further up in the chain might ask us for supported formats. Without this MEDIA_BUS_FMT_FIXED is assumed which then breaks display output with mxsfb since it can't determine a proper bus format. We handle the bus formats that correspond to the DSI formats the bridge can potentially output (see chapter 13.6 of the i.MX 8MQ reference manual) - which matches what xsfb can input.

This tablet display is unique and hence must be added to documentation. Unfortunately, it's real make and number is not known due to obscure and missing documentation and lack of writing on the display assembly itself. So the natural alternative that came to mind is to name the panel after the device that contained it (an Android tablet). Hopefully that isn't an issue. I can confirm that the parameters that I've obtained are correct since they came from a dump of the original Android OS. Signed-off-by:

dp-aux-bus.yaml says we can list an eDP panel as a child of an eDP controller node to represent the fact that the panel is connected to the controller's DP AUX bus. Let's add it to the ps8640 bindings. Signed-off-by:
