Hello, this patch series adds a dt property for the pcf2127 driver to configure the battery switch-over behavior. The default behavior for battery switch-over has changed with PCF2131. For PCF2127, PCF2129 and PCA2129 the default is battary switch-over and battery low power detection is enabled. For PCF2131 this is now the opposite. At least PCF2127 and PCF2129 are not recomended for new designs. This leaves the PCF2131 as "replacement" part. This patch series introduces the nxp,battery-switch-over optional property. With this property the PWRMNG bits of the Control_3 register can be changed. I have tested this on a device with PCF2129 and one with PCF2131.
