Subject: [PATCH 07/10] MIPS: Netlogic: Core wakeup changes for XLP2XX
Date: Sun, 11 Aug 2013 14:43:57 +0530 [thread overview]
Message-ID: <1376212440-21038-8-git-send-email-jchandra@broadcom.com> (raw)
In-Reply-To: <1376212440-21038-1-git-send-email-jchandra@broadcom.com>
On XLP2xx, wakeup code does not need to enable clock on the core.
Update xlp/wakeup.c to handle this.
