From ea737554451d9fae1207e84a3d2c495bbfcd3f08 Mon Sep 17 00:00:00 2001 From: Vikram Pandita Date: Wed, 7 Sep 2011 09:19:23 -0700 Subject: usb: musb: omap2+: fix context api's RxFifoSz, TxFifoSz, RxFifoAddr, TxFifoAddr are all indexed registers. So before doing a context save or restore, INDEX register should be set, then only one gets to the right register offset.
