rtc: simplified /proc/driver/rtc handling

2007-05-08T18:15:18+00:00

This simplifies the RTC procfs 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 also removes the class_interface hook, now that its last remaining user is gone. (That API is usable only with a "struct class_device".) It's another step towards being able to remove "struct class_device".

rtc: remove /sys/class/rtc-dev/*

2007-05-08T18:15:18+00:00

This simplifies the /dev support by removing a superfluous class_device (the /sys/class/rtc-dev stuff) and the class_interface that hooks it into the rtc core. Accordingly, if it's configured then /dev 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".

[PATCH] RTC framework driver for CMOS RTCs

2007-02-11T18:51:32+00:00

This is an "RTC framework" driver for the "CMOS" RTCs which are standard on PCs and some other platforms. That's MC146818 compatible silicon. Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only one will be able to claim the RTC irq) include: - This leverages both the new RTC framework and the driver model; both PNPACPI and platform device modes are supported. (A separate patch creates a platform device on PCs where PNPACPI isn't configured.) - It supports common extensions like longer alarms. (A separate patch exports that information from ACPI through platform_data.) - Likewise, system wakeup events use "real driver model support", with policy control via sysfs "wakeup" attributes and and using normal rtc ioctls to manage wakeup. (Patch in the works. The ACPI hooks are known; /proc/acpi/alarm can vanish. Making it work with EFI will be a minor challenge to someone with e.g. a MiniMac.) It's not yet been tested on non-x86 systems, without ACPI, or with HPET. And the RTC framework will surely have teething pains on "mainstream" PC-based systems (though must embedded Linux systems use it heavily), not limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also, the ALSA rtctimer code doesn't use the new RTC API. Otherwise, this should be a no-known-regressions replacement for the old drivers/char/rtc.c driver, and should help the non-embedded distros (and the new timekeeping code) start to switch to the framework. Note also that any systems using "rtc-m48t86" are candidates to switch over to this more functional driver; the platform data is different, and the way bytes are read is different, but otherwise those chips should be compatible.

[PATCH] AT91RM9200 RTC

2006-12-10T17:55:40+00:00

The new Atmel AT91SAM9261 and AT91SAM9260 processors do not have the internal RTC peripheral. This RTC driver is therefore AT91RM9200-specific. This patch renames rtc-at91.c to rtc-at91rm9200.c, and changes the name of the configuration option.

[PATCH] add rtc-omap driver

2006-12-07T16:39:40+00:00

This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

[PATCH] RTC class: Kconfig improvements

2006-10-01T07:39:25+00:00

Small updates to make the RTC class Kconfig text be more informative. This should help folk used to the drivers/char/rtc.c support, or a single RTC, be slightly less surprised by the differences. Also, adds a new RTC_DEBUG option to predefine DEBUG in the framework and its drivers, while debugging. That's getting to be a standard idiom, and it's pretty useful.
