[PATCH 1/3] usb: otg: Improve phy handling
This patch series improves the phy handling. The first patch fixes the problem that the phy driver, when build as module, can be unloaded when the phy is in use. The second patch takes up Kishon's work and adds device tree support to the otg library. New in this patch is that devm_usb_get_phy_by_phandle() will return with -EPROBE_DEFER, if the requested phy has not registered itself yet. The third patch registers the mxs-phy as a USB_PHY_TYPE_USB2 phy, so that the ci13xxx_imx driver can reqeust it via the devm_usb_get_phy_by_phandle() function. These patches apply to v3.6-rc3 and have ben successfully tested on mx28 and mx53 (with an improved version of the chipidea driver though). regards, Marc -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
