drm/panel: simple: Add missing display timing flags for KOE TX26D202VM0BWA

2024-07-05T07:38:01+00:00

[ Upstream commit 37ce99b77762256ec9fda58d58fd613230151456 ] KOE TX26D202VM0BWA panel spec indicates the DE signal is active high in timing chart, so add DISPLAY_FLAGS_DE_HIGH flag in display timing flags. This aligns display_timing with panel_desc.

drm/panel: ilitek-ili9881c: Fix warning with GPIO controllers that sleep

2024-07-05T07:37:57+00:00

[ Upstream commit ee7860cd8b5763017f8dc785c2851fecb7a0c565 ] The ilitek-ili9881c controls the reset GPIO using the non-sleeping gpiod_set_value() function. This complains loudly when the GPIO controller needs to sleep. As the caller can sleep, use gpiod_set_value_cansleep() to fix the issue.

drm/panel: simple: Add missing Innolux G121X1-L03 format, flags, connector

[ Upstream commit 11ac72d033b9f577e8ba0c7a41d1c312bb232593 ] The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , add the missing bus_format. Add missing connector type and bus_flags as well. Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is capable of both RGB 18bit/24bit panel, the current configuration uses 18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6. Support for the 24bit mode would require another entry in panel-simple with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which is out of scope of this fix.

[ Upstream commit 5ff5505b9a2d827cae3f95dceba258c963138175 ] Given that failing to find a DSI host causes the driver to defer probe, make use of dev_err_probe() to log the reason.

So far only the Synopsis DSI driver was using this panel and it is always switching to video mode, independent of this flag being set. Other DSI drivers might handle this differently, so add the flag.
