| |
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
