Detailed Description

AXP192 Power Output Channel Control.

Provides enable/disable, voltage get/set, and channel enumeration for all 7 power output channels (3 DCDC + 4 LDO-type). Voltage setters automatically quantize to the nearest valid step. Inherits from PmicChannelBase for polymorphic PMIC integration.
