2010-08-11rtc/pxa: remove unnecessary private ops->ioctl()Wan ZongShun
We shouldn't implement private ops->ioctl() unless absolutely necessary. pxa series RTC driver's ioctl() is unnecessary, since RTC subsystem has implement the ioctl() very well,so we can only use the API of '.alarm_irq_enable' and '.update_irq_enable' to do enable irq action.

2010-08-11rtc/nuc900: fix checking of args during time-settingWan ZongShun
When a user application wants to set the rtc time, the RTC subsystem takes advantage of 'rtc_valid_tm(tm)' to check 'rtc_time *tm' value validity, it make sure the 'tm->tm_year' is larger than 70,so if '70< tm_year < 100', the '(settm->tm_year - 100)' will be negative. ' Setting the negative value to hardware register will be invalid, so I add the 'if' condition to make sure set a valid value to register.

2010-08-11nuc900/rtc: change the waiting for device ready implementWan ZongShun
- add an mdelay(1) to the polling loop to cause less frequent access to the hardware register. - change the return value from ENODEV to EPERM if the loop timed out. I think the 'Operation not permitted' description is more suitable for the meaning of 'check_rtc_access_enable()' function, it just be used to judge rtc access operation is permitted or not.

2010-06-29rtc: fix ds1388 time corruptionJoakim Tjernlund
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.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
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.

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.

The bug is an oops when dev_get_drvdata() returned null in cmos_update_irq_enable(). The call tree looks like this: rtc_dev_ioctl() => rtc_update_irq_enable() => cmos_update_irq_enable() It's caused by a race condition in the module initialization.

logic" This reverts commit 9c0a342c45b2d98209ac473ea7a429ddd5c1b473 because it was included without proper signoffs from RTC maintainers.

2010-05-06rtc: omap: let device wakeup capability be configured from chip init logicSekhar Nori
The rtc-omap driver currently hardcodes the RTC wakeup capability to be "not capable". While this seems to be true for existing OMAP1 boards which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always be wake up source from its "deep sleep" mode. This patch lets the wakeup capability to be set from platform data and does not override the setting from the driver. For DA850/OMAP-L138, this is done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc() Note that this patch does not change the behavior on any existing OMAP1 board since the platform device registration sets the wakeup capability to 0 by default.
