* rtc: Namespace fixupThomas Gleixner2010-12-132-24/+24
| | | | | | | | | rtctimer_* is already occupied by sound/core/rtctimer.c. Instead of fiddling with that, rename the new functions to rtc_timer_* which reads nicer anyway. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: John Stultz <johnstul@us.ibm.com>
* RTC: Remove UIE emulationJohn Stultz2010-12-101-104/+0

* RTC: Rework RTC code to use timerqueue for eventsJohn Stultz2010-12-103-225/+390
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks a large portion of the generic RTC code to in-effect virtualize the rtc interrupt code. The current RTC interface is very much a raw hardware interface. Via the proc, /dev/, or sysfs interfaces, applciations can set the hardware to trigger interrupts in one of three modes: AIE: Alarm interrupt UIE: Update interrupt (ie: once per second) PIE: Periodic interrupt (sub-second irqs) The problem with this interface is that it limits the RTC hardware so it can only be used by one application at a time. The purpose of this patch is to extend the RTC code so that we can multiplex multiple applications event needs onto a single RTC device. This is done by utilizing the timerqueue infrastructure to manage a list of events, which cause the RTC hardware to be programmed to fire an interrupt for the next event in the list. In order to preserve the functionality of the exsting proc,/dev/ and sysfs interfaces, we emulate the different interrupt modes as follows: AIE: We create a rtc_timer dedicated to AIE mode interrupts. There is only one per device, so we don't change existing interface semantics. UIE: Again, a dedicated rtc_timer, set for periodic mode, is used to emulate UIE interrupts. Again, only one per device. PIE: Since PIE mode interrupts fire faster then the RTC's clock read granularity, we emulate PIE mode interrupts using a hrtimer. Again, one per device. With this patch, the rtctest.c application in Documentation/rtc.txt passes fine on x86 hardware. However, there may very well still be bugs, so greatly I'd appreciate any feedback or testing!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does two modifications: (1) Adjust enable/disable IRQs location,enable it after rtc registration and disable it prior to unregistration. (2) Put 'platform_set_drvdata(pdev, nuc900_rtc)' in front of rtc registration still be safety, though there is no need to do this, when I move enable irq after rtc registration, I think still put 'platform_set_drvdata' before rtc registration that would be a good habit.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the logic while writing new date/time to the chip. The driver incorrectly wrote back register values to different registers and even with wrong mask. The patch adds clearing of the VLF register, which should be cleared if all date/time values are set.

| * rtc: fix ds1388 time corruptionJoakim Tjernlund2010-06-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ds1307 driver misreads the ds1388 registers when checking for 12 or 24 hour mode. Instead of checking the hour register it reads the minute register. Therefore the driver thinks minutes >= 40 has the 12HR bit set and resets the minute register by zeroing the high bits. This results in minutes are reset to 0-9, jumping back in time 40 or 50 minutes. The time jump is also written back to the RTC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

| * mfd: AB3100 register access change to abx500 APIMattias Wallin2010-05-281-23/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
