From a75d048e1409bb2bae0d71645c4f6247d2ce9276 Mon Sep 17 00:00:00 2001 From: "Aric D. Blumer" Date: Thu, 30 Jul 2009 13:42:30 -0400 Subject: USB: ohci-pxa27x: Reconfigure power settings on resume On resume, the power-related bits in UHCRHDA were not being set, so they would default to the reset state. For PXA3xx devices, OCPM must be cleared, but it was remaining set from resume reset. Signed-off-by: Aric D.
