Use the dev_err_probe() helper, instead of open-coding the same operation. This also adds a nice hint in /sys/kernel/debug/devices_deferred. Reviewed-by:

Decomposing fence containers don't seem to make any sense here. So just remove the function entirely and call dma_fence_wait() directly. Signed-off-by:

Following the previous patch, let's introduce a generic panel-lvds binding that documents the panels that don't have any particular constraint documented. Reviewed-by:

The lvds.yaml file so far was both defining the generic LVDS properties (such as data-mapping) that could be used for any LVDS sink, but also the panel-lvds binding. That last binding was to describe LVDS panels simple enough, and had a number of other bindings using it as a base to specialise it further. However, this situation makes it fairly hard to extend and reuse both the generic parts, and the panel-lvds itself. Let's remove the panel-lvds parts and leave only the generic LVDS properties.

When we have the entire DRM state, retrieving the connector state only requires the drm_connector pointer. Fortunately for us, we have allocated it as a part of the vc4_hdmi structure, so we can retrieve get a pointer by simply accessing our field in that structure. Signed-off-by:

Even though we have the other drm_display_info fields reset, the DC modes are missing. This shouldn't be an issue since it's explicitly reset every time a new EDID is parsed. Suggested-by:

Mark screen buffers in system memory with FBINFO_VIRTFB. Otherwise, fbdev deferred I/O marks mmap'ed areas of system memory with VM_IO. (There's an inverse relationship between the two flags.)

Recently we added generic "edp-panel"s probed by EDID. To support panels in this way we look at the panel ID in the EDID and look up the panel in a table that has power sequence timings. If we find a panel that's not in the table we will still attempt to use it but we'll use conservative timings. While it's likely that these conservative timings will work for most nearly all panels, the performance of turning the panel off and on suffers. We'd like to be able to reliably detect the case that we're using the hardcoded timings without relying on parsing dmesg. This allows us to implement tests that ensure that no devices get shipped that are relying on the conservative timings. Let's add a new sysfs entry to panel devices. It will have one of: * UNKNOWN - We tried to detect a panel but it wasn't in our table. * HARDCODED - We're not using generic "edp-panel" probed by EDID. * A panel name - This is the name of the panel from our table.

If only linear modifier is advertised, since there are many drivers that only linear supported, the DRM core should handle this rather than open-coding in every driver. However, there are legacy drivers such as radeon that do not support modifiers but infer the actual layout of the underlying buffer. Therefore, a new flag fb_modifiers_not_supported is introduced for these legacy drivers, and allow_fb_modifiers is replaced with this new flag. v3: - change the order as follows: 1. add fb_modifiers_not_supported flag 2. add default modifiers 3. remove allow_fb_modifiers flag - add a conditional disable in amdgpu_dm_plane_init() v4: - modify kernel docs v5: - modify kernel docs Signed-off-by:

pm_runtime_get_sync() will increase the rumtime PM counter even when it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error. Besides, a matching decrement is needed on the error handling path to keep the counter balanced. Signed-off-by:
