+         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
