From b086e392b1d435f6abc1dab32b21ee5559cb53de Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:21:02 -0700 Subject: rtc: rtc-spear: convert spear_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.
