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.

Now there are no users of the return value of the drm_panel_prepare(), drm_panel_unprepare(), drm_panel_enable() and drm_panel_disable() calls. Usually these calls are performed from the atomic callbacks, where it is impossible to return an error. Stop returning error codes and return void instead.

2025-04-22drm: panel: jd9365da: fix reset signal polarity in unprepareHugo Villeneuve
commit a8972d5a49b4 ("drm: panel: jd9365da-h3: fix reset signal polarity") fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare(). It was not done in jadard_unprepare() because of an incorrect assumption about reset line handling in power off mode. After looking into the datasheet, it now appears that before disabling regulators, the reset line is deasserted first, and if reset_before_power_off_vcioo is true, then the reset line is asserted. Fix reset polarity by inverting gpiod_set_value() second argument in in jadard_unprepare().

2025-03-30drm/panel/sharp-ls043t1le01: Use _multi variantsAnusha Srivatsa
Move away from using deprecated API and use _multi variants if available. Use mipi_dsi_msleep() and mipi_dsi_usleep_range() instead of msleep() and usleep_range() respectively. Used Coccinelle to find the _multi variant APIs,replacing mpi_dsi_msleep() where necessary and for returning dsi_ctx.accum_err in these functions. mipi_dsi_dcs_write() does not have a corresponding _multi() variant. Replacing it with mipi_dsi_dcs_write_seq_multi() instead. This change is manual. The Coccinelle script is the same as the one in commit c8ba07caaecc ("drm/panel/synaptics-r63353: Use _multi variants") v2: Use mipi_dsi_write_buffer_multi() in place of mipi_dsi_dcs_write(). (Dmitry) v3: add commit details where the same coccinelle script is used and remove the actual script from commit log. Use mipi_dsi_dcs_write_seq_multi() for mipi_dsi_dcs_write() (Doug) Cc: Maxime Ripard <mripard@kernel.org> Cc: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Cc: Tejas Vipin <tejasvipin76@gmail.com> Cc: Doug Anderson <dianders@chromium.org> Signed-off-by: Anusha Srivatsa <asrivats@redhat.com> Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Link: https://lore.kernel.org/r/20250326-b4-panel-ls043t1le01-v3-1-96c554c0ea2b@redhat.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>
