The Lenovo ThinkPad T14s Gen 7 (Snapdragon X2 Elite) uses this 14"
1920x1200 panel. Without an entry panel-edp warns at every boot ("Unknown
panel BOE 0x0d9b, using conservative timings").The panel's timing requirements are not published, so use the same delays as the other BOE NE140WUM entries (delay_200_500_e80). With them the panel trains and lights up reliably on this machine. edid-decode (hex): 00 ff ff ff ff ff ff 00 09 e5 9b 0d 00 00 00 00 0c 23 01 04 a5 1e 13 78 03 ce 51 9a 5f 58 8d 26 16 4f 53 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 33 3f 80 dc 70 b0 3c 40 30 20 36 00 2e bc 10 00 00 1a 00 00 00 fd 00 28 3c 4c 4c 10 01 0a 20 20 20 20 20 20 00 00 00 fe 00 42 4f 45 20 4e 4a 0a 20 20 20 20 20 20 00 00 00 fc 00 4e 45 31 34 30 57 55 4d 2d 4e 34 31 0a 01 ca 70 20 79 02 00 81 00 15 74 1a 00 00 03 01 28 3c 00 00 60 42 60 42 3c 00 00 00 00 8d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 cc 90 Assisted-by: LLM Signed-off-by: Luke Macken <[email protected]> --- Changes in v2: - Include the panel's EDID in the commit message (Doug Anderson) drivers/gpu/drm/panel/panel-edp.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/panel/panel-edp.c b/drivers/gpu/drm/panel/panel-edp.c index 5d7d696b7..6d6bce01f 100644 --- a/drivers/gpu/drm/panel/panel-edp.c +++ b/drivers/gpu/drm/panel/panel-edp.c @@ -2078,6 +2078,7 @@ static const struct edp_panel_entry edp_panels[] = { EDP_PANEL_ENTRY('B', 'O', 'E', 0x0d45, &delay_200_500_e80, "NV116WHM-N4B"), EDP_PANEL_ENTRY('B', 'O', 'E', 0x0d73, &delay_200_500_e80, "NE140WUM-N6S"), EDP_PANEL_ENTRY('B', 'O', 'E', 0x0d98, &delay_200_500_e50_po2e200_d100, "NV140FHM-N5B"), + EDP_PANEL_ENTRY('B', 'O', 'E', 0x0d9b, &delay_200_500_e80, "NE140WUM-N41"), EDP_PANEL_ENTRY('B', 'O', 'E', 0x0db3, &delay_200_500_e80, "NV153WUM-N42"), EDP_PANEL_ENTRY('B', 'O', 'E', 0x0ddf, &delay_200_500_e80, "NV116WHM-T01"), EDP_PANEL_ENTRY('B', 'O', 'E', 0x386e, &delay_200_500_e80, "NV116WH2-M30"), -- 2.43.0
