Subject: [PATCH RESEND 1/8] rtc: rtc-at91sam9: convert at91_rtc_driver to dev_pm_ops
Date: Wed, 17 Apr 2013 10:06:47 +0900 [thread overview]
Message-ID: <003001ce3b07$d5f29da0$81d7d8e0$%han@samsung.com> (raw)
Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.
