+Introduction
+------------
 This is an introduction to driver-model multi uclass PMIC IC's support.
 At present it's based on two uclass types:
-- UCLASS_PMIC      - basic uclass type for PMIC I/O, which provides common
-                     read/write interface.
-- UCLASS_REGULATOR - additional uclass type for specific PMIC features,
-                     which are Voltage/Current regulators.

+How doees it work
+-----------------
 The Power Management Integrated Circuits (PMIC) are used in embedded systems
 to provide stable, precise and specific voltage power source with over-voltage
 and thermal protection circuits.
 
 The single PMIC can provide various functions by single or multiple interfaces,
-like in the example below.

 the PMIC devices should also support this. By the pmic and regulator API's,
