PowerPC has been a long time user of the generic RTC abstraction, so hook up rtc-generic: - Create the "rtc-generic" platform device if ppc_md.get_rtc_time is set, - Kill rtc-ppc, as rtc-generic offers the same functionality in a more generic way, and supports autoloading through udev.

The rtc-parisc driver is not PA-RISC specific at all, as it uses the existing (but deprecated) generic RTC infrastructure ([gs]et_rtc_time()). Rename the driver from rtc-parisc to rtc-generic. Signed-off-by:

Simple RTC driver for the MSP430 firmware on the DM355 EVM board. Other than not supporting atomic reads/writes of all four bytes, this is reasonable as a basic no-alarm RTC. Signed-off-by:

With PXA27x and above, a new RTC hardware block was added in addition to the legacy one which is also found on the SA1100 SOC family. This second RTC block is called "wristwatch" and "periodic interrupt" and works independently from the other RTC block. The driver offers provides : - a 1Hz ticking clock - a periodic alarm, in the 1Hz to 1000Hz range - a one shot alarm Signed-off-by:

This adds a driver for the RTC inside the TWL4030 multi-function device. It's a fairly basic RTC, with a wake-capable alarm. Note that many of the pre-release Overo boards now in circulation can't effectively use this RTC, because of a wiring error that puts its TWL chip into "secure" mode. (As in "secure yourself against tampering".) This isn't an issue on other OMAP3 boards now supported in mainline, such as Beagle and Labrador. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.) Signed-off-by: -

This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

This patch adds support for the Simtek STK17TA8 timekeeping chip. The STK17TA8 is quite similar to the DS1553, but differs in register layout and in various control bits in the registers. I chose to make this a new driver to avoid confusion in the code and to not get lost in #ifdefs. Signed-off-by:

This is a new-style i2c driver for ST M41T80 series RTC chip, derived from works by Alexander Bigga <ab@mycable.de> who wrote the original rtc-m41txx.c based on drivers/i2c/chips/m41t00.c driver. This driver supports M41T8[0-4] and M41ST8[457]. The old m41t00 driver supports M41T00, M41T81 and M41T85(M41ST85). While the M41T00 chip is now supported by rtc-ds1307 driver, this driver does not include support for the chip. [akpm@linux-foundation.org: remove bogus `static'] Signed-off-by:

Tested on the AT32AP7000/ATSTK1000. Driver does only suport time, wake up and a very simple alarm, because of hardware limitations. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 From: David Brownell <david-b@pacbell.net> - Strike some alarm setup code that's no longer needed. (This patch seems to have gotten lost somewhere...) - Make the driver name (and its module alias) match what the platform setup code uses, so the driver can bind and hotplug.

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". Signed-off-by:
