In probe() we create the drm_device, and then register the MHI controller. In remove(), we should unregister the controller first, then remove the drm_device. Update the remove() operations to match. Signed-off-by:

Offload the balancing of init and destroy calls to DRM managed APIs. mutex destroy for ->cntl_mutex is not called during device release and destroy workqueue is not called in error path of create_qdev(). So, use DRM managed APIs to manage the release of resources and avoid such problems. Signed-off-by:

These panels are used by Mediatek MT8173 Chromebooks, and they used to work with the downstream v4.19 kernel without any specified delay. Back in the v4.19 kernel, they used the "little white lie" approach, which is making the devicetree claim a specific panel's compatible string for many different panels. That was a common solution before the generic edp-panel driver. After we uprevved the device to a newer kernel and used the edp-panel driver, we saw multiple devices reporting warnings of using an unknown panel and falling back to the conservative timings, which means that they turn on/off much more slowly than they should. We tried to fill in the timings for those panels, but we failed to find all the data sheets for them. Therefore, instead of having them use the default conservative timings, update them with less-conservative timings from other panels of the same vendor. The panels should still work under those timings, and we can save some delays and suppress the warnings. Signed-off-by:

Add the support of powered_on_to_enable delay as the minimum time that needs to have passed between the panel powered on and enable may begin. This delay is seen in BOE panels as the minimum delay of T3+T4+T5+T6+T8 in the eDP timing diagrams. Signed-off-by:

The original rationale for commit cd456f8d ("drm: Restrict stackdepot usage to builtin drm.ko") was that depot_save_stack() (which is what we used back then) wasn't exported. stack_depot_save() (which is what we use now) is exported however, so relax the dependency allow CONFIG_DRM_MM_DEBUG with DRM=m.

The current documentation of drm_atomic_state says that it's the "global state object". This is confusing since, while it does contain all the objects affected by an update and their respective states, if an object isn't affected by this update it won't be part of it. Thus, it's not truly a "global state", unlike object state structures that do contain the entire state of a given object. Reviewed-by:

Commits 63e83c1d ("drm: Consolidate connector arrays in drm_atomic_state"), b8b5342b ("drm: Consolidate plane arrays in drm_atomic_state") and 5d943aa6 ("drm: Consolidate crtc arrays in drm_atomic_state") moved the object pointer and their state pointer to an intermediate structure storing both. The CRTC commit didn't update the doc of the crtcs field to reflect that, and the doc for the planes and connectors fields mention that they are pointers to an array of structures with per-$OBJECT data. The private_objs field was added later on by commit b430c27a ("drm: Add driver-private objects to atomic state") reusing the same sentence than the crtcs field, probably due to copy and paste. While these fields are indeed pointers to an array, each item of that array contain a pointer to the object structure affected by the update, and its old and new state. There's no per-object data there, and there's more than just a pointer to the objects. Let's rephrase those fields a bit to better match the current situation. Acked-by:

Some fields of drm_atomic_state have been documented in-line, but some were documented in the main kerneldoc block before the structure. Since the former is the preferred option in DRM, let's move all the fields to an inline documentation. Acked-by:

The pm_runtime_enable function increases the power disable depth, which means that we must perform a matching decrement on the error handling path to maintain balance within the given context. Additionally, we need to address the same issue for pm_runtime_get_sync. We fix this by invoking pm_runtime_disable and pm_runtime_put_sync when error returns.
