Subject: [PATCH] add-pcf50633-06-RTC_AIE-ioctl
|
||
|
|
|
||
|
|
Hey,
|
||
|
|
|
||
|
|
the legacy application 'atd' from Russ Nelson/Nils Faerber, used by Qtopia, to
|
||
|
|
schedule alarms currently fails to start as the the above ioctl is failing.
|
||
|
|
The other drivers in drivers/rtc implement the above ioctl and we can
|
||
|
|
implement it too.
|
||
|
|
|
||
|
|
The code to mask/unmask the RTC alarm is copied from the set_alarm routine and
|
||
|
|
adapted to use the reg_set_bit_mask and reg_set_clear_mask.
|
||
|
|
|
||
|
|
It is compiling, so it must work. Please welcome me the lkml way ;)
|
||
|
|
|
