2025-06-27drm/panel: panel-simple: get rid of panel_dpi hackMaxime Ripard
The empty panel_dpi struct was only ever used as a discriminant, but it's kind of a hack, and with the reworks done in the previous patches, we shouldn't need it anymore. Let's get rid of it.

2025-06-27drm/panel: panel-simple: Add function to look panel data upMaxime Ripard
Commit de04bb0089a9 ("drm/panel/panel-simple: Use the new allocation in place of devm_kzalloc()") moved the call to drm_panel_init into the devm_drm_panel_alloc(), which needs a connector type to initialize properly. In the panel-dpi compatible case, the passed panel_desc structure is an empty one used as a discriminant, and the connector type it contains isn't actually initialized. It is initialized through a call to panel_dpi_probe() later in the function, which used to be before the call to drm_panel_init() that got merged into devm_drm_panel_alloc(). So, we do need a proper panel_desc pointer before the call to devm_drm_panel_alloc() now. All cases associate their panel_desc with the panel compatible and use of_device_get_match_data, except for the panel-dpi compatible. In that case, we're expected to call panel_dpi_probe, which will allocate and initialize the panel_desc for us. Let's create such a helper function that would be called first in the driver and will lookup the desc by compatible, or allocate one if relevant.

2025-06-27drm/panel: panel-simple: Make panel_simple_probe return its panelMaxime Ripard
In order to fix the regession introduced by commit de04bb0089a9 ("drm/panel/panel-simple: Use the new allocation in place of devm_kzalloc()"), we need to move the panel_desc lookup into the common panel_simple_probe() function. There's two callers for that function, the probe implementations of the platform and MIPI-DSI drivers panel-simple implements. The MIPI-DSI driver's probe will need to access the current panel_desc to initialize properly, which won't be possible anymore if we make that lookup in panel_simple_probe(). However, we can make panel_simple_probe() return the initialized panel_simple structure it allocated, which will contain a pointer to the associated panel_desc in its desc field. This doesn't fix de04bb0089a9 ("drm/panel/panel-simple: Use the new allocation in place of devm_kzalloc()") still, but makes progress towards that goal.

2025-06-27drm/panel: panel-simple: make panel_dpi_probe return a panel_descMaxime Ripard
If the panel-simple driver is probed from a panel-dpi compatible, the driver will use an empty panel_desc structure as a descriminant. It will then allocate and fill another panel_desc as part of its probe. However, that allocation needs to happen after the panel_simple structure has been allocated, since panel_dpi_probe(), the function doing the panel_desc allocation and initialization, takes a panel_simple pointer as an argument. This pointer is used to fill the panel_simple->desc pointer that is still initialized with the empty panel_desc when panel_dpi_probe() is called. Since commit de04bb0089a9 ("drm/panel/panel-simple: Use the new allocation in place of devm_kzalloc()"), we will need the panel connector type found in panel_desc to allocate panel_simple. This creates a circular dependency where we need panel_desc to create panel_simple, and need panel_simple to create panel_desc. Let's break that dependency by making panel_dpi_probe simply return the panel_desc it initialized and move the panel_simple->desc assignment to the caller. This will not fix the breaking commit entirely, but will move us towards the right direction.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2024-07-22drm/panel: Avoid warnings w/ panel-simple/panel-edp at shutdownDouglas Anderson
At shutdown if you've got a _properly_ coded DRM modeset driver then you'll get these two warnings at shutdown time: Skipping disable of already disabled panel Skipping unprepare of already unprepared panel These warnings are ugly and sound concerning, but they're actually a sign of a properly working system. That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here.

2024-05-28drm/panel: simple: Add a comment about unprepare+disable at shutdown/removeDouglas Anderson
It's the responsibility of a correctly written DRM modeset driver to call drm_atomic_helper_shutdown() at shutdown time and that should be disabling / unpreparing the panel if needed. Panel drivers shouldn't be calling these functions themselves. A recent effort was made to fix as many DRM modeset drivers as possible [1] [2] [3] and most drivers are fixed now. Unfortunately, it's very difficult to know exactly which DRM modeset drivers are using panel-simple due to the sheer number of panels it handles. For now, we'll leave the calls and just add a comment to keep people from copying this code.
