+ If you say yes to this option, support will be included for the
+ P2WI (Push/Pull 2 Wire Interface) controller embedded in some sunxi
+ SOCs.
+ The P2WI looks like an SMBus controller (which supports only byte
+ accesses), except that it only supports one slave device.
+ This interface is used to connect to specific PMIC devices (like the
+ AXP221).
