Hello, This patch series adds basic support for the X-Powers' AXP221 PMIC.
At the moment the MFD device only exposes the AXP221 regulators but other subdevices might be added later. I'm still waiting for inputs regarding the ipsout regulator representation: * The ipsout regulator is currently represented as a fixed regulator providing a 5v output, and this is not exactly the case. AFAIU (here's is the datasheet traduction if you want to check [1]), the ipsout output is a multiplexer that choose among vbus (5V), acin (12V which is then converted to 5V) and the battery power supply (3,5 -> 4,2 V). This means the output voltage of ipsout vary between 3,5V and 5V. How can we express this kind of muxer in the regulator framework (is there already something available ?) ? Note that the power supply selection is automatic, though we could force one power supply, but then we loose the ability to unplug one power supply without impacting the system.
