It is (now) drivers/gpu/drm/panel/panel-boe-btl507212-w677l.c and arch/arm/boot/dts/omap5-letux-cortex15-common.dtsi (for the basic dsi definitions) arch/arm/boot/dts/pyra-display.dtsi (for the specific display) All this is merged by some arch/arm/boot/dts/omap5-letux-cortex15-v5.3+pyra-v5.2.dts (I know there are quite a lot of variants but it is a modular system potentially able to accomodate a non-omap processor but the same display).
