The patch titled
rtc-sa1100 rtc_wklarm.enabled bugfixes
has been removed from the -mm tree. Its filename was
rtc-sa1100-rtc_wklarmenabled-bugfixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: rtc-sa1100 rtc_wklarm.enabled bugfixes
From: David Brownell <david-b@xxxxxxxxxxx>
Some rtc-sa1100 bugfixes:
- The read_alarm() method reports the rtc_wkalrm.enabled field properly.
This patch is already in the handhelds.org tree.
- And the set_alarm() method now handles that flag correctly, rather than
making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
warning messages. (Those calls are best made in suspend/resume methods.)
Note that while this SA1100/PXA RTC is fully capable of waking those ARM
processors from sleep states, that mechanism isn't properly supported on
either processor family, or in this driver. Some boards have board-specific
PM glue providing partial workarounds for the weak generic PM support.
