From 79ad3b5add4a683af02d1b51ccb699d1b01f1fbf Mon Sep 17 00:00:00 2001 From: Benoit Goby Date: Wed, 9 Mar 2011 16:28:56 -0800 Subject: usb: host: Add EHCI driver for NVIDIA Tegra SoCs The Tegra 2 SoC has 3 EHCI compatible USB controllers. This patch adds the necessary glue to allow the ehci-hcd driver to work on Tegra 2 SoCs. The platform data is used to configure board-specific phy settings and to configure the operating mode, as one of the ports may be used as a otg port. For additional power saving, the driver supports powering down the phy on bus suspend when it is used, for example, to connect an internal device that use an out-of-band remote wakeup mechanism (e.g. a gpio).
