* usb: otg: add device tree support to otg libraryKishon Vijay Abraham I2013-01-25
| | | | | | | | | | | Added an API devm_usb_get_phy_by_phandle(), to get usb phy by passing a device node phandle value. This function will return a pointer to the phy on success, -EPROBE_DEFER if there is a device_node for the phandle, but the phy has not been added, or a ERR_PTR() otherwise.

* usb: otg: utils: add facilities in phy lib to support multiple PHYs of same typeKishon Vijay Abraham I2013-01-25
| | | | | | | | | | | | | | | | In order to add support for multipe PHY's of the same type, new API's for adding PHY and getting PHY has been added. Now the binding information for the PHY and controller should be done in platform file using usb_bind_phy API. And for getting a PHY, the device pointer of the USB controller and an index should be passed. Based on the binding information that is added in the platform file, usb_get_phy_dev will return the appropriate PHY. Already existing API's to add and get phy by type is not removed. These API's are deprecated and will be removed once all the platforms start to use the new API. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: otg: add an api to bind the usb controller and phyKishon Vijay Abraham I2013-01-25
| | | | | | | | | | | In order to support platforms which has multiple PHY's (of same type) and which has multiple USB controllers, a new design is adopted wherin the binding information (between the PHY and the USB controller) should be passed to the PHY library from platform specific file (board file). So added a new API to pass the binding information. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: change phy notify connect/disconnect APIPeter Chen2012-11-15
| | | | | | | | | | | | | The old parameter "port" is useless for phy notify, as one usb phy is only for one usb port. New parameter "speed" stands for the device's speed which is on the port, this "speed" parameter is needed at some platforms which will do some phy operations according to device's speed.

* usb: phy: fix build breakVenu Byravarasu2012-09-06
| | | | | | | | | | | | | During phy interface separation from otg.h, as the enum "usb_otg_state" was having multiple otg states info and removal of member 'state' of this enum type from usb_phy struct did not generate any compilation issues, I removed member state from struct usb_phy. As this is causing build break in musb code, adding member 'state' to usb_phy structure. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: otg: Move phy interface to separate file.Venu Byravarasu2012-09-05
As otg.h is containing lots of phy interface related stuff, moving all phy interface related stuff to new file named phy.h Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
