From: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxxxx> Add Texas Instruments' LP8864/LP8866 bindings into LP8860 converting them into YAML format simultaneously. While here, drop the index of the "led" subnode, this one is neither used nor mandated by the drivers. All the *-cells properties are therefore not required. Move the file into backlight directory because all of the LP886x drivers are special backlight products.
