This was used out-of-tree as a hack for resolving issues where some systems expect the backlight to turn on automatically at boot, while others expect to manage the backlight status via a DRM/panel driver. Those issues have since been fixed upstream in pwm_bl.c without device tree hacks, and so this un-documented property should no longer be useful.
