From f6d92a05c86754d62eabc84856d2035d0de3ddc3 Mon Sep 17 00:00:00 2001 From: Ajay Kumar Gupta Date: Fri, 6 Feb 2009 17:32:35 +0530 Subject: USB: otg: adding nop usb transceiver NOP transceiver is used by all the usb transceiver which are mostly autonomous and doesn't require any programming or which are built into the usb ip itself.NOP transceiver only allocates the memory for struct xceiv and calls otg_set_transceiver() so function call to otg_get_transceiver() will return a valid transceiver. NOP transceiver device should be registered by calling usb_nop_xceiv_register() from platform files.
