Date: Wed, 17 Apr 2013 10:07:17 +0900 From: Jingoo Han <jg1.han@...sung.com> To: 'Andrew Morton' <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, 'Alessandro Zummo' <a.zummo@...ertech.it>, rtc-linux@...glegroups.com, 'Jingoo Han' <jg1.han@...sung.com> Subject: [PATCH RESEND 2/8] rtc: rtc-bfin: convert bfin_rtc_driver to dev_pm_ops Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management.
