+lp855x bindings
+
+Required properties:
+  - compatible: "ti,lp8550", "ti,lp8551", "ti,lp8552", "ti,lp8553",
+                "ti,lp8556", "ti,lp8557"
+  - reg: I2C slave address (u8)
+  - dev-ctrl: Value of DEVICE CONTROL register (u8). It depends on the device.
+
+Optional properties:
+  - bl-name: Backlight device name (string)
+  - init-brt: Initial value of backlight brightness (u8)
+  - pwm-period: PWM period value. Set only PWM input mode used (u32)
+  - rom-addr: Register address of ROM area to be updated (u8)
+  - rom-val: Register value to be updated (u8)
+
+Example:
+
+        /* LP8556 */
+        backlight@2c {
+                compatible = "ti,lp8556";
+                reg = <0x2c>;
+
+                bl-name = "lcd-bl";
+                dev-ctrl = /bits/ 8 <0x85>;
+                init-brt = /bits/ 8 <0x10>;
+        };
+
+        /* LP8557 */
+        backlight@2c {
+                compatible = "ti,lp8557";
+                reg = <0x2c>;
+
+                dev-ctrl = /bits/ 8 <0x41>;
+                init-brt = /bits/ 8 <0x0a>;
+
+                /* 4V OV, 4 output LED string enabled */
+                rom_14h {
+                        rom-addr = /bits/ 8 <0x14>;
+                        rom-val = /bits/ 8 <0xcf>;
+                };
+        };
