The nxp,battery-switch-over property is used to control the switch-over, battery low detection and extra power fail detection functions. The PCF2131 has a different default value for the PWRMNG bits. It is set to 0x7: battery switch-over function is disabled, only one power supply (VDD); battery low detection function is disabled. This is the opposite of the default of the PCF2127/PCA2129 and PCF2129. With the nxp,battery-switch-over the behavior can be controlled through the device tree.
