2022-02-21drm/panel: Rename Sony ACX424 to Novatek NT35560Linus Walleij
A code drop from Sony Mobile reveals that the ACX424 panels are built around the Novatek NT35560 panel controllers so just bite the bullet and rename the driver and all basic symbols so that we can modify this driver to cover any other panels also using the Novatek NT35560 display controller.

2022-02-15drm/panel-edp: Allow querying the detected panel via debugfsDouglas Anderson
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 debugfs 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.

2022-02-09spi: make remove callback a void functionUwe Kleine-König
The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2021-10-14drm/panel: Delete panel on mipi_dsi_attach() failureBrian Norris
Many DSI panel drivers fail to clean up their panel references on mipi_dsi_attach() failure, so we're leaving a dangling drm_panel reference to freed memory. Clean that up on failure. Noticed by inspection, after seeing similar problems on other drivers. Therefore, I'm not marking Fixes/stable.

2021-10-14drm/panel: innolux-p079zca: Delete panel on attach() failureBrian Norris
If we fail to attach (e.g., because 1 of 2 dual-DSI controllers aren't ready), we leave a dangling drm_panel reference to freed memory. Clean that up on failure. This problem exists since the driver's introduction, but is especially relevant after refactored for dual-DSI variants.
