Hi,
 the following 4 patches make some improvements to the twl4030
 phy.  Together with some other patches I have for twl4030_charger,
 they allow for better automatic control of charging.

 In particular, the status of the ID pin is assessed and the
 result in communicated to the charger drivers.
 There is also support for conveying the max current negotiated by a
 host to the charger.

Comments most welcome.

thanks,
NeilBrown
