17 | Purpose : This Module defines the power management device driver
18 | for the G23 protocol stack.
19 |
20 | This driver is used to control all power related functions
21 | such as charger and battery control. The driver does support
22 | multiple devices and therefore no open and close functionality
23 | is supported. The driver can be configured to signal different
24 | state transitions, for example battery level has reached the
25 | "battery low" level. This is done by setting an OS signal or
26 | calling a specified call-back function.
