+	Definition: It specifies a table of brightness values that can be programmed
+			    into WLED_SINK for exponential dimming which provides smooth brightness
+			    change. There should be exactly 256 values in the table and they should
+			    be at most 15 bits long. This table would be used only if the

 Following properties are for child subnodes that are needed for WLED preflash
 (or torch), flash and switch. These child subnodes can be specified only for
 PMICs that has WLED5 (e.g. PM8150L).
