Subject: [ 37/49] USB: xhci - fix bit definitions for IMAN register
Date: Tue, 26 Mar 2013 16:01:34 -0700	[thread overview]
Message-ID: <20130326225843.417183557@linuxfoundation.org> (raw)
In-Reply-To: <20130326225839.554028294@linuxfoundation.org>

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dmitry Torokhov <dtor@vmware.com>

commit f8264340e694604863255cc0276491d17c402390 upstream.

According to XHCI specification (5.5.2.1) the IP is bit 0 and IE is bit 1
of IMAN register. Previously their definitions were reversed.

Even though there are no ill effects being observed from the swapped
definitions (because IMAN_IP is RW1C and in legacy PCI case we come in
with it already set to 1 so it was clearing itself even though we were
setting IMAN_IE instead of IMAN_IP), we should still correct the values.

This patch should be backported to kernels as old as 2.6.36, that
contain the commit 4e833c0b87a30798e67f06120cecebef6ee9644c "xhci: don't
re-enable IE constantly".
