linux-toradex.git/include/linux/usb/phy.h, branch v3.9 Linux kernel for Apalis and Colibri modules usb: otg: add device tree support to otg library 2013-01-25T08:20:14+00:00 Kishon Vijay Abraham I kishon@ti.com 2013-01-25T02:33:25+00:00 5d3c28b5a42df5ceaa854901ba2cccb76883c77e 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 type 2013-01-25T08:20:14+00:00 Kishon Vijay Abraham I kishon@ti.com 2013-01-25T02:33:22+00:00 0fa4fab4ee46470ccd463c83be95434936942e05 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 phy 2013-01-25T08:20:09+00:00 Kishon Vijay Abraham I kishon@ti.com 2013-01-25T02:33:21+00:00 b4a83e4df1bc864e89d3bb90e97f9caab656545d 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>
