* [PATCH] spin/rwlock init cleanupsIngo Molnar2006-06-27
| | | | | | | | | | | | | | | | | | | | | locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Add v3020 RTC supportRaphael Assenat2006-06-25
| | | | | | | | | | | | | | | | | | | | This patch adds support for the v3020 RTC from EM Microelectronic. The v3020 RTC is designed to be connected on a bus using only one data bit. Since any data bit may be used, it is necessary to specify this to the driver by passing a struct v3020_platform_data pointer (see include/linux/rtc-v3020.h) to the driver. Part of the following code comes from the kernel patchs produced by Compulab for their products. The original file (available here: http://raph.people.8d.com/misc/emv3020.c) was released under the terms of the GPL license.

* [PATCH] RTC: rtc-dev UIE emulationAtsushi Nemoto2006-06-25
| | | | | | | | | | | | | Import genrtc's RTC UIE emulation (CONFIG_GEN_RTC_X) to rtc-dev driver with slight adjustments/refinements. This makes UIE-less rtc drivers work better with programs doing read/poll on /dev/rtc, such as hwclock. This emulation should not harm rtc drivers with UIE support, since rtc_dev_ioctl() calls underlaying rtc driver's ioctl() first.

* [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).
