The axp20x rsb driver handles many different devices.
Duplicating its code in a generic regulator driver permits
to probe/remove individual devices.

The X-Powers AXP803 PMIC is close to the AXP809 with more outputs.
It is used in some Allwinner boards as the Sinovoip BananaPi M64
and the Pine A64.
