Tomi, * Tomi Valkeinen <tomi.valkeinen@xxxxxx> [140121 03:01]: > Add DT support for panel-dpi. Looks like this patch did not get merged or am I missing something? As you probably are aware, we have at least these boards needing it before we can remove the omap3 legacy support: board-am3517evm.c board-cm-t35.c board-devkit8000.c board-ldp.c board-overo.c We could probably set the display timings based on the compatible flag in the driver if that's an issue? And then board-omap3pandora.c also needs support for panel_tpo_td043mtea1_platform_data.
