| | | | | | | | | For non-otg mode, we keep the usage of disconnect line between phy analog and digital unchanging; for otg mode, at peripheral role, we keep the usage unchanging too, at host role, the digital part needs to know dp/dm change to respond device's data pulse when it is at low power mode.

* usb: phy: make PHY driver selection possible by controller driversRoger Quadros2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert PHY Drivers from menuconfig to menu so that the PHY drivers can be explicitely selected by the controller drivers. USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

Besides, we call mxs_phy_disconnect_line at this API to close the connection between USB PHY and controller, after that, the line state from controller is SE0. Once the PHY is out of power, without calling mxs_phy_disconnect_line, there are unknown wakeups due to dp/dm floating at device mode. Signed-off-by: Peter Chen <peter.chen@freescale.com>
