2023-12-03drm/panel: boe-tv101wum-nl6: Fine tune Himax83102-j02 panel HFP and HBPCong Yang1-4/+4
[ Upstream commit cea7008190ad65b4aaae6e94667a358d2c10a696 ] The refresh reported by modetest is 60.46Hz, and the actual measurement is 60.01Hz, which is outside the expected tolerance. Adjust hporch and pixel clock to fix it. After repair, modetest and actual measurement were all 60.01Hz. Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime /DSI CLK. Assume that the DSI controller could not make the mode that we requested(presumably it's PLL couldn't generate the exact pixel clock?). If you use a different DSI controller, you may need to readjust these parameters. Now this panel looks like it's only used by me on the MTK platform, so let's change this set of parameters.

2023-10-12drm/panel: Move AUX B116XW03 out of panel-edp back to panel-simpleDouglas Anderson2-29/+35
In commit 5f04e7ce392d ("drm/panel-edp: Split eDP panels out of panel-simple") I moved a pile of panels out of panel-simple driver into the newly created panel-edp driver. One of those panels, however, shouldn't have been moved. As is clear from commit e35e305eff0f ("drm/panel: simple: Add AUO B116XW03 panel support"), AUX B116XW03 is an LVDS panel. It's used in exynos5250-snow and exynos5420-peach-pit where it's clear that the panel is hooked up with LVDS. Furthermore, searching for datasheets I found one that makes it clear that this panel is LVDS. As far as I can tell, I got confused because in commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on") Jitao Shi added "DRM_MODE_CONNECTOR_eDP". That seems wrong. Looking at the downstream ChromeOS trees, it seems like some Mediatek boards are using a panel that they call "auo,b116xw03" that's an eDP panel. The best I can guess is that they actually have a different panel that has similar timing. If so then the proper panel should be used or they should switch to the generic "edp-panel" compatible. When moving this back to panel-edp, I wasn't sure what to use for .bus_flags and .bus_format and whether to add the extra "enable" delay from commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on"). I've added formats/flags/delays based on my (inexpert) analysis of the datasheet. These are untested. NOTE: if/when this is backported to stable, we might run into some trouble. Specifically, before 474c162878ba ("arm64: dts: mt8183: jacuzzi: Move panel under aux-bus") this panel was used by "mt8183-kukui-jacuzzi", which assumed it was an eDP panel. I don't know what to suggest for that other than someone making up a bogus panel for jacuzzi that's just for the stable channel.

2023-10-10drm/panel: boe-tv101wum-nl6: Completely pull GPW to VGL before TP termRuihai Zhou1-3/+1
The sta_himax83102 panel sometimes shows abnormally flickering horizontal lines. The front gate output will precharge the X point of the next pole circuit before TP(TouchPanel Enable) term starts, and wait until the end of the TP term to resume the CLK. For this reason, the X point must be maintained during the TP term. In abnormal case, we measured a slight leakage at point X. This because during the TP term, the GPW does not fully pull the VGL low, causing the TFT to not be closed tightly. To fix this, we completely pull GPW to VGL before entering the TP term. This will ensure that the TFT is closed tightly and prevent the abnormal display.

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.

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 Raynal1-0/+81
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.

2023-08-01drm/panel: sitronix-st7789v: add Inanbo T28CP45TN89 supportSebastian Reichel1-0/+25
UNI-T UTi260b has a Inanbo T28CP45TN89 v17 panel. I could not find proper documentation for the panel apart from a technical drawing, but according to the vendor U-Boot it is based on a Sitronix st7789v chip. I generated the init sequence by modifying the default one until proper graphics output has been seen on the device.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. 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. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
