From 04ebc35973745c1b9af281931d6ebd3842496e8e Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:21:01 -0700 Subject: [PATCH] rtc: rtc-omap: convert omap_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.
