rtc: add max_user_freq to sysfs

2007-10-16T16:43:13Z

drivers/char/rtc.c exposed a sysctl to change the maximum frequency at which a non-root user could ask the RTC to generate interrupts (via the RTC_IRQP_SET ioctl). This value is no longer available under the new RTC subsystem, so add it to sysfs for each RTC device. Works for me on x86_64 (both reads and writes), using rtc-cmos.

rtc: remove rest of class_device

Finish converting the RTC framework so it no longer uses class_device. Signed-off-by: David Brownell Acked-by: Greg Kroah-Hartman Acked-By: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: simplified rtc sysfs attribute handling

2007-05-08T18:15:18Z

This simplifies the RTC sysfs support by removing the class_interface that hooks it into the rtc core. If it's configured, then sysfs support is now part of the RTC core, and is never a separate module. It's another step towards being able to remove "struct class_device".

rtc: rtc interfaces don't use class_device

2007-05-08T18:15:18Z

This patch removes class_device from the programming interface that the RTC framework exposes to the rest of the kernel. Now an rtc_device is passed, which is more type-safe and streamlines all the relevant code.

[PATCH] RTC gets sysfs wakealarm attribute

2007-02-12T17:48:31Z

This adds a new "wakealarm" sysfs attribute to RTC class devices which support alarm operations and are wakeup-capable: - It reads as either empty, or the scheduled alarm time as seconds since the POSIX epoch. (That time may already have passed, since nothing currently enforces one-shot alarm semantics.) - It can be written with an alarm time in the future, again seconds since the POSIX epoch, which enables the alarm. - It can be written with an alarm time not in the future (such as 0, the start of the POSIX epoch) to disable the alarm. Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN": alarm after 10 minutes: # echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm alarm tuesday evening 10pm: # date -d '10pm tuesday' "+%s" > wakealarm disable alarm: # echo 0 > wakealarm This resembles the /proc/acpi/alarm file in that nothing happens when the alarm triggers ... except possibly waking the system from sleep. It's also like that in a nasty way: not much can be done to prevent one task from clobbering another task's alarm settings. It differs from that file in that there's no in-kernel date parser. Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't set up correctly, so they won't yet behave with this attribute.

[PATCH] RTC class uses subsys_init

2006-10-01T07:39:25Z

This makes RTC core components use "subsys_init" instead of "module_init", as appropriate for subsystem infrastructure. This is mostly useful for statically linking drivers in other parts of the tree that may provide an RTC interface as a secondary functionality (e.g. part of a multifunction chip); they won't need to worry so much about drivers/Makefile link order.
