* rtc: ds1305/ds1306 driverDavid Brownell2008-07-24
| | | | | | | | | | | | | Support the Dallas/Maxim DS1305 and DS1306 RTC chips. These use SPI, and support alarms, NVRAM, and a trickle charger for use when their backup power supply is a supercap or rechargeable cell. This basic driver doesn't yet support suspend/resume or wakealarms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ramtron FM3130 is a chip with two separate devices inside, RTC clock and FRAM. This driver provides only RTC functionality. This chip is met in lots of custom boards with AT91SAMXXXX CPU I work with, is cheap and in no way better or worse than any other RTC on market. While it is mostly met on much smaller devices, I think it is great to have it supported in Linux.

* rtc: at91sam9 RTC support (RTT and/or RTC)David Brownell2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was extracted from 2.6.23-at91 patch and updated: - Relies on now-merged platform updates, which associate the RTT hardware address with each RTT and use the "at91_rtt" name. - RTC framework related fixes and cleanups, notably: * removed now-needless suspend/resume clock offset logic * alarm read/write now respects the "enabled" flag * suspend always disables update irqs * shutdown (and startup) disables all irqs - Misc cleanup: * use dev_*() messaging * add comments * remove globals, * ... etc - Don't force use of RTT0 and GPBR0. Either resource may need to be used for other purposes (like NO_HZ support). - Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips (it has both RTT and RTC). Driver binding uses bus_find_device() to avoid needing any kind of "timer library" code when there's more than one RTT module. (This timer can be used as an RTC, to support NO_HZ operation, or potentially for other stuff. The choice is a per-system policy.)

* [PATCH] RTC framework driver for CMOS RTCsDavid Brownell2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] drivers/acorn/char/pcf8583.[hc] vs. RTC subsystemG. Liakhovetski2006-06-25
| | | | | | | | | | | | | | A port of the driver for the pcf8583 i2c rtc controller to the generic RTC framework by Alessandro Zummo. Based on drivers/acorn/char/{pcf8583.[hc],i2c.c}. Hopefully, acorn can be converted too to use this driver in the future. Signed-off-by: G.

* [PATCH] "RTC-framework" driver for DS1307 and similar RTC chipsDavid Brownell2006-06-25
| | | | | | | | | | | | | | | | | This is an "RTC-framework" driver for DS1307 and similar RTC chips, It should be a full replacement for the existing ds1337.c driver (using the older RTC glue), giving a net increase in the number of RTC chips that work out-of-the-box. There's a whole cluster of RTCs that are very similar, but the 1337 driver was a bit too picky to work with most of them. Still no support for RTC alarm IRQs (on chips that support them).
