The functional differences between these modes can be found in the "Control and Operation" chapter of the AXP806 (in Chinese) and AXP805 (in English) datasheets. These include how the PMIC responds to external signals, whether it takes an external voltage reference or uses its own, and whether the EN/PWRON pin functions as an enable switch or power button. We already support both slave and master mode. This patch adds a property for describing the self-working mode, and reworks the description for the mode properties.
