+TI LMU (Lighting Management Unit) device tree bindings
+
+TI LMU driver supports lighting devices below.
+
+   Name                  Child nodes
+  ------      ---------------------------------
+  LM3631       Backlight and regulator
+  LM3632       Backlight and regulator
+  LM3633       Backlight, LED and fault monitor
+  LM3695       Backlight
+  LM36274      Backlight and regulator
+
+Required properties:
+  - compatible: Should be one of:
+                "ti,lm3631"
+                "ti,lm3632"
+                "ti,lm3633"
+                "ti,lm3695"
+		"ti,lm36274"
+  - reg: I2C slave address.
+         0x11 for LM3632
+         0x29 for LM3631
+         0x36 for LM3633
+         0x63 for LM3695
+         0x11 for LM36274
+
+Optional properties:
+  - enable-gpios: A GPIO specifier for hardware enable pin.
+  - ramp-up-us: Current ramping from one brightness level to
+		the a higher brightness level.
+		Range from 2048 us - 117.44 s
+  - ramp-down-us: Current ramping from one brightness level to
+		  the a lower brightness level.
+		  Range from 2048 us - 117.44 s
+  - ti,brightness-resolution - This determines whether to use 8 bit brightness
+			       mode or 11 bit brightness mode.  If this value is
+			       not set the device is defaulted to the preferred
+			       8bit brightness mode per 7.3.4.1 of the data
+			       sheet.  This setting can either be in the parent
+			       node or as part of the LED child nodes.  This
+			       is determined by the part itself if the strings
+			       have a common brightness register or individual
+			       brightness registers.
+			       The values are 255 (8bit) or 2047 (11bit).
+
+Required node:
+  - backlight: All LMU devices have backlight child nodes.
+               For the properties, please refer to [1].
+
+Optional nodes:
+  - fault-monitor: Hardware fault monitoring driver for LM3633 and LM3697.
+    Required properties:
+      - compatible: Should be one of:
+                    "ti,lm3633-fault-monitor"
+  - leds: LED properties for LM3633. Please refer to [2].
+	  LED properties for LM36274. Please refer to [4].
+  - regulators: Regulator properties for LM3631 and LM3632.
+                Please refer to [3].
