Subject: [PATCH 2/3] ARM: PXA27x: save/restore PWER on suspend/resume
Date: Sun, 26 Feb 2012 16:47:41 +0300 [thread overview]
Message-ID: <1330264062-5750-2-git-send-email-anarsoul@gmail.com> (raw)
In-Reply-To: <1330264062-5750-1-git-send-email-anarsoul@gmail.com>
Bootloader can clobber PWER value, so save it state on suspend.
