drm/panel: boe-tv101wum-nl6: Completely pull GPW to VGL before TP term

2023-10-19T21:11:00+00:00

[ Upstream commit 258dd5e6e65995ee85a941eed9a06708a36b1bfe ] 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.

drm/panel: simple: Fix AUO G121EAN01 panel timings according to the docs

2023-08-14T12:50:47+00:00

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.

The driver can be built as a module, however the lack of the MODULE_DEVICE_TABLE macro prevents it from being automatically probed from the DT in such case. Add the missed macro to make sure the module can load automatically.
