-The regulator node name should be initialized with a string to get matched
-with their hardware counterparts as follow. The valid names are:
-
-	-LDOn 	:	for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
-			and 32-35.
-			example: LDO1, LDO2, LDO35.
-	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 10.
-			example: BUCK1, BUCK5, BUCK10.

-The max77802 regulator supports two different operating modes: Normal and Low
-Power Mode. Some regulators support the modes to be changed at startup or by
-the consumers during normal operation while others only support to change the
-mode during system suspend. The standard regulator suspend states binding can
-be used to configure the regulator operating mode.
-
-The regulators that support the standard "regulator-initial-mode" property,
-changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
-
-The possible values for "regulator-initial-mode" and "regulator-mode" are:
-	1: Normal regulator voltage output mode.
-	3: Low Power which reduces the quiescent current down to only 1uA
-
-The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
-header and can be included by device tree source files.
-
-The standard "regulator-mode" property can only be used for regulators that
-support changing their mode to Low Power Mode during suspend. These regulators
-are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
-been enabled for the given suspend state using "regulator-on-in-suspend" and
-has not been disabled for that state using "regulator-off-in-suspend".

+description: |
+  This is a part of device tree bindings for Maxim MAX77802 Power Management
+  Integrated Circuit (PMIC).
+
+  The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
+  regulators.
+
+  See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
+  additional information and example.
+
+  Certain regulators support "regulator-initial-mode" and "regulator-mode".
+  The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
+  and their meaning is:
+    1 - Normal regulator voltage output mode.
+    3 - Low Power which reduces the quiescent current down to only 1uA
+
+  The standard "regulator-mode" property can only be used for regulators that
+  support changing their mode to Low Power Mode during suspend. These
+  regulators are: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
+  regulator has been enabled for the given suspend state using
+  "regulator-on-in-suspend" and has not been disabled for that state using
+  "regulator-off-in-suspend".
