* phy: core: Let node ptr of PHY point to PHY and not of PHY providerKishon Vijay Abraham I2014-07-221-1/+1
| | | | | | | | | | | In case of multi-phy PHY providers, each PHY should be modeled as a sub node of the PHY provider. Then each PHY will have a different node pointer (node pointer of sub node) than that of PHY provider. Added this provision in the PHY core. Also fixed all drivers to use the updated API.

* phy: usb: sunxi: Introduce Allwinner A31 USB PHY supportMaxime Ripard2014-05-141-11/+22
| | | | | | | | | | The USB phy controller in the A31 differs mostly from the older controllers because it has a clock dedicated for each phy, while the older ones were having a single clock for all the phys.

* phy: sunxi: Rework phy initializationMaxime Ripard2014-05-141-24/+18
| | | | | | | | | | Move the phy initialization and variables declaration to the loop itself, since it is where it really belongs. Also remove all the temporary variables, we can use the structure members directly.

* PHY: sunxi: Add driver for sunxi usb phyHans de Goede2014-03-031-0/+331
The Allwinner A1x / A2x SoCs have 2 or 3 usb phys which are all accessed through a single set of registers. Besides this there are also some other phy related bits which need poking, which are per phy, but shared between the ohci and ehci controllers, so these are also controlled from this new phy driver.
