The twl4030_charger is physically paired with the twl4030 USB phy,
so the drivers need to be able to reliably find each other.
twl4030_charger currently uses usb_get_phy(), which works if there is
only one phy to choose from, but is not reliable in more complex
configurations.
These patches add a new interface to allow a phy to be found given a
device node, and then use that interface in twl4030_charger so that
it finds its sibling in the devicetree, and gets the phy associated
with that.
===
This is a resend with improved documentation. I'm hoping this can go
in to the next merge window, though should it go through usb/phy or
power???
Thanks,
NeilBrown
