I've no real opinion on this, I do NOT like the introduction of a
third version of the i2c / rsb and axp code (we already have both
a u-boot and a kernel version to maintain of both).

Given that and rumors I've heard of a new PSCI version which may make
things like shutdown optional, I would prefer to wait for such a new
PSCI version and jump directly to that.

But ultimately I defer to Ian here, so Ian whatever you say goes :)

Regards,

Hans
