From 4dc8eb13c2b99a334ee703061e75ee71d582dd1f Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:20:58 -0700 Subject: [PATCH] rtc: rtc-at91sam9: convert at91_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.
