From 07783397c6e3757de805bda5e1139a9e47aa7d74 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Tue, 17 Sep 2013 11:20:21 -0700 Subject: [PATCH] rtc: rtc-pl031: Set wakeup flag prior to registering rtcdev In some recent testing, I noticed the CLOCK_REALTIME_ALARM clockid wasn't functioning on my vexpress qemu environment. Looking into it I noticed the pl031 rtc driver doesn't set the wakeup flag on the device until after registering the device with the RTC subsystem. This causes the alarmtimer subsystem to not see the pl031 driver as a valid backing device, and that resuls in alarm clockids getting ENOTSUPP errors. Thus be sure to set the wakeup flag on the device prior to registering the rtcdev so the pl031 rtc driver can be used as the backing alarmtimer device.
