2016-03-25rtc: abx80x: handle the oscillator failure bitMylène Josserand
Handle the Oscillator Failure ('OF') bit from Oscillator Status register (0x1D). This bit is cleared on set_time function and is read each time the date/time is read, but only in case of XT Oscillator selection. In RC mode, this bit is always set.

2016-03-25rtc: abx80x: handle autocalibrationMylène Josserand
The autocalibration is separated in two bits to set in Oscillator Control register (0x1c) : - OSEL bit to select the oscillator type (XT or RC). - ACAL bit to select the autocalibration type. These functionnalities are exported in sysfs entries : "oscillator" and "autocalibration". Respectively, the values are "xtal" for XT oscillator and "rc" for RC oscillator and 0 to disable the autocalibration cycle, 512 for a 512 seconds autocalibration cycle and 1024 for a cycle of 1024 seconds. Examples : Set to XT Oscillator echo xtal > /sys/class/rtc/rtc0/device/oscillator Activate an autocalibration every 512 seconds echo 512 > /sys/class/rtc/rtc0/device/autocalibration Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2016-03-25rtc: rv8803: workaround i2c HW issueAlexandre Belloni
The rv8803 has a 60µs window where it will not answer on the i2c bus. It also means there will be no ack for the communication. Make sure communication is tried multiple times when this happens (the i2c subsystem mandates -ENXIO is that case but the number of retries is host specific). The critical parts are the probe function and the alarm callback so make sure we handle the failure there.

2016-03-19rtc: asm9260: remove incorrect __init/__exit annotationsArnd Bergmann
The probe and remove callbacks of the platform driver are marked __init and __exit, respectively. However, this is not a correct way to annotate them, as it will result in those sections to be discarded at link time or after boot, while we can actually call them again based on manual unbinding, or deferred probing. Kbuild warns about the problem: WARNING: drivers/rtc/rtc-asm9260.o(.data+0x0): Section mismatch in reference from the variable asm9260_rtc_driver to the function .init.text:asm9260_rtc_probe() This removes the annotations, so we no longer branch into missing code and avoid the warning.

2016-03-19rtc: s3c: Don't print an error on probe deferralJavier Martinez Canillas
The clock and source clock looked up by the driver may not be available just because the clock controller driver was not probed yet so printing an error in this case is not correct and only adds confusion to users. However, knowing that a driver's probe was deferred may be useful so it can be printed as a debug information.

There are only a few differences between PCF2127 and PCF2129 (PCF2127 has 512 bytes of general purpose SRAM and count-down timer). The rtc-pcf2127 driver currently doesn't use the PCF2127 specific functionality and Kconfig help text already says this driver supports PCF2127/29, so we can simply add pcf2129 to device id list.

2016-03-14rtc: ds1685: actually spin forever in poweroff error pathJosh Poimboeuf
objtool reports the following warnings: drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x0: duplicate frame pointer save drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x3: duplicate frame pointer setup drivers/rtc/rtc-ds1685.o: warning: objtool: ds1685_rtc_work_queue()+0x0: frame pointer state mismatch The warning message needs to be improved, but what it really means in this case is that ds1685_rtc_poweroff() has a possible code path where it can actually fall through to the next function in the object code, ds1685_rtc_work_queue(). The bug is caused by the use of the unreachable() macro in a place which is actually reachable. That causes gcc to assume that the printk() immediately before the unreachable() macro never returns, when in fact it does. So gcc places the printk() at the very end of the function's object code. When the printk() returns, the next function starts executing. The surrounding comment and printk message state that the code should spin forever, which explains the unreachable() statement. However the actual spin code is missing.

2016-03-14rtc: ds3232: use rtc->ops_lock to protect alarm operationsAkinobu Mita
ds3232->mutex is used to protect for alarm operations which need to access status and control registers. But we can use rtc->ops_lock instead. rtc->ops_lock is held when most of rtc_class_ops methods are called, so we only need to explicitly acquire it from irq handler in order to protect form concurrent accesses.

2016-03-14rtc: ds3232: fix issue when irq is shared several devicesAkinobu Mita
ds3232-core requests irq with IRQF_SHARED, so irq can be shared by several devices. But the irq handler for ds3232 unconditionally disables the irq at first and the irq is re-enabled only when the interrupt source was the ds3232's alarm. This behaviour breaks the devices sharing the same irq in the various scenarios. This converts to use threaded irq and remove outdated code in suspend/resume paths.

2016-03-14rtc: ds3232: fix read on /dev/rtc after RTC_AIE_ONAkinobu Mita
The rtctest (tools/testing/selftests/timers/rtctest.c) found that reading ds3232 rtc device immediately return the value 0x20 (RTC_AF) without waiting alarm interrupt. This is because alarm_irq_enable() of ds3232 driver changes RTC_AF flag in rtc->irq_data. So calling ioctl with RTC_AIE_ON generates invalid value in rtc device. The lower-level driver should not touch rtc->irq_data directly. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
