lib: lvgl: obtain LVGL_DISPLAY_DEV_NAME from devicetree (52282110) · Commits · Wenxi XU / zephyr

It is not possible completely remove options like LVGL_DISPLAY_DEV_NAME without heavy reworking of LVGL support because lvgl_init needs the name of the device, and LVGL_*_RES_MAX options to define internal buffers. Signed-off-by:
