* phy: Introduce to_usbphy conversion functionSascha Hauer2016-09-291-0/+8
| | | | | | | | | | The generic phy support layer has the necessary list handling and phy retrieval functions, so we should reuse them for usb phys. This adds a phy_to_usbphy() conversion function which drivers can implement which attach to the generic phy layer and are really usb phys. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* phy: Introduce of_phy_get_by_phandleSascha Hauer2016-09-291-0/+8
| | | | | | | | | Currently generic phy support assumes that the standard phy binding from dts/Bindings/phy/phy-bindings.txt is used. This adds a helper function which can be used to retrieve a phy when this standard binding is not used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* add generic PHY frameworkLucas Stach2014-11-041-0/+240
This brings in the generix PHY framework from Linux. I tried to strip it down as much as possible while keeping it useful. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
