From 7032d512cff979319f308e02223d0cf39b6e9a91 Mon Sep 17 00:00:00 2001 From: Pavankumar Kondeti Date: Wed, 8 Dec 2010 13:37:07 +0530 Subject: MSM: Add USB suport for QSD8x50 OTG driver takes care of putting hardware into low power mode. Hence make peripheral and host devices as children of OTG device and let runtime PM takes care of notifying peripheral and host state to OTG device. VBUS power up and shutdown routines are implemented by modem processor. As RPC infrastructure is not available, configure USB in peripheral only mode.
