2023-08-16drm/panel: simple: Fix Innolux G156HCE-L01 LVDS clockLuca Ceresoli
This panel has been implemented in commit eae7488814b5 ("drm/panel-simple: Add Innolux G156HCE-L01 panel entry") with a higher clock than the typical one mentioned on the documentation to avoid flickering on the unit tested. Testing on a different unit shows that the panel actually works with the intended 70.93 MHz clock and even lower frequencies so the flickering is likely caused either by a defective unit or by other different components such as the bridge.

2023-08-14drm/panel: simple: Fix AUO G121EAN01 panel timings according to the docsLuca Ceresoli
Commit 03e909acd95a ("drm/panel: simple: Add support for AUO G121EAN01.4 panel") added support for this panel model, but the timings it implements are very different from what the datasheet describes. I checked both the G121EAN01.0 datasheet from [0] and the G121EAN01.4 one from [1] and they all have the same timings: for example the LVDS clock typical value is 74.4 MHz, not 66.7 MHz as implemented. Replace the timings with the ones from the documentation. These timings have been tested and the clock frequencies verified with an oscilloscope to ensure they are correct. Also use struct display_timing instead of struct drm_display_mode in order to also specify the minimum and maximum values.

2023-08-01drm/panel: sitronix-st7789v: Check display IDMiquel Raynal
A very basic debugging rule when a device is connected for the first time is to access a read-only register which contains known data in order to ensure the communication protocol is properly working. This driver lacked any read helper which is often a critical piece for speeding-up bring-ups. Add a read helper and use it to verify the communication with the panel is working as soon as possible in order to inform the user early if this is not the case. As this panel may work with no MISO line, the check is discarded in this case. Upon error, we do not fail probing but just warn the user, in case the DT description would be lacking the Rx bus width (which is likely on old descriptions) in order to avoid breaking existing devices.

As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

I have no idea what the prior magic values mean, and I have no idea what my replacement (extracted from [1]) magic values mean. What I do know, is that these new values result in a much better picture, where the blacks are really black (as you would expect on an AMOLED display) instead of grey-ish.

2023-06-08drm/panel: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the drm panel drivers from always returning zero in the remove callback to the void returning variant.
