rtc_timer_do_work() only judges -ETIME failure of__rtc_set_alarm(), but doesn't handle other failures like -EIO, -EBUSY, etc. If there is a failure other than -ETIME, the next rtc_timer will stay in the timerqueue. Then later rtc_timers will be enqueued directly because they have a later expires time, so the alarm irq will never be programmed. When such failures happen, this patch will retry __rtc_set_alarm(), if still can't program the alarm time, it will remove current rtc_timer from timerqueue and fetch next one, thus preventing it from affecting other rtc timers.

Currently, ab8500 doesn't set uie_unsupported of rtc_device, while it doesn't support UIE, see ab8500_rtc_set_alarm(). Thus, when going through rtc_update_irq_enable()->rtc_timer_enqueue(), there's a chance it has an alarm timer1 queued before which is going to fired, so this update timer2 will be queued because it isn't the leftmost one, which means rtc_timer_enqueue() will return 0. This will result in two problems: 1) UIE EMUL will not be used. 2) When the alarm timer1 is fired, in rtc_timer_do_work() timer2 will fail to set the alarm time, so this rtc will disfunctional due to timer2 with the earliest expires in the timerqueue. So, rtc drivers must set this flag if they don't support UIE. Signed-off-by:

The alarm interrupt handler also reads registers which are part of SNVS and need clocks enabled. However, the resume function is called after IRQ's have been enabled, hence this leads to a abort: Unhandled fault: external abort on non-linefetch (0x1008) at 0x908c604c Internal error: : 1008 [#1] ARM Modules linked in: CPU: 0 PID: 421 Comm: sh Not tainted 3.18.0-rc5-00135-g0689c67-dirty #1592 task: 8e03e800 ti: 8cad8000 task.ti: 8cad8000 PC is at snvs_rtc_irq_handler+0x14/0x74 LR is at handle_irq_event_percpu+0x3c/0x144 Fix this by using the .{suspend/resume}_noirq callbacks instead of .{suspend/resume} .

Add clock enable and disable support for the SNVS peripheral, which is required for using the RTC within the SNVS block. The clock is not strictly enforced, as this would break the i.MX devices. The clocking for the i.MX devices seems to be enabled elsewhere and enabling RTC SNVS for Vybrid results in a crash. This patch adds the clock support but also makes it optional so Vybrid platform can use the clock if defined while making sure not to break i.MX. Signed-off-by:

Drop the vendor-prefix from the "ti,system-power-controller" device-tree property name. It has been agreed to make "system-power-controller" a standard property and to drop the vendor-prefix that is currently used by several drivers. Note that drivers that have used "<vendor>,system-power-controller" in a released kernel will need to support both versions. Signed-off-by:

As suggested by Uwe, instead of clearing oscillator failure bit unconditionally at driver load, this patch adds proper handling of the flag. The driver now returns -ENODATA when reading time from the device and oscillator failure bit is set. The flag is now cleared only when the a new time value is pushed to the device. Signed-off-by:

The month register of ISL12057 RTC chip includes a century bit which reports overflow of year register from 99 to 0. This bit can also be written, which allows using it to extend the time interval the chip can support from 99 to 199 years. This patch adds support for century overflow bit in tm to regs and regs to tm helpers in ISL12057 driver. This was tested by putting a device 100 years in the future (using a specific kernel due to the inability of userland tools such as date or hwclock to pass year 2038), rebooting on a kernel w/ this patch applied and verifying the device was still 100 years in the future.

When Intersil ISL12057 support was added by commit 70e12337 ("rtc: Add support for Intersil ISL12057 I2C RTC chip"), two masks for time registers values imported from the device were either wrong or omitted, leading to additional bits from those registers to impact read values: - mask for hour register value when reading it in AM/PM mode. As AM/PM mode is not the usual mode used by the driver, this error would only have an impact on an externally configured RTC hour later read by the driver. - mask for month value. The lack of masking would provide an erroneous value if century bit is set. This patch fixes those two masks. Fixes: 70e12337 ("rtc: Add support for Intersil ISL12057 I2C RTC chip") Signed-off-by:

MCP7940x is same RTC as MCP7941x. The difference is that MCP7941x chips contain additional EEPROM on a different i2c address. DS1307 driver already supports MCP7941x, so just add a new i2c device id and rename functions and defines accordingly. Signed-off-by:

Configure the RTC as system-power controller, which allows the system to be powered off as well as woken up again on subsequent RTC alarms. Note that the PMIC needs to be put in SLEEP (rather than OFF) mode to maintain RTC power. Specifically, this means that the PMIC ti,pmic-shutdown-controller property must be left unset in order to be able to wake up on RTC alarms. Tested on BeagleBone Black (rev A5). Signed-off-by:

Make sure not to register the class device until after the device has been configured. Currently, the device is not fully configured (e.g. 24-hour mode) when the class device is registered, something which involves driver callbacks for example to read the current time. Signed-off-by:

Remove some debug messages and return errors from subsystems rather than always fail with -EIO. Note that the class-registration error has already been logged by rtc core. Signed-off-by:

Use writel instead of writeb when disabling interrupts at probe as ALARM2 is not cleared otherwise on some IP-block revisions (e.g. AM3352). Note that the driver currently never enables the ALARM2 interrupt. Signed-off-by:

The platform device must be registered as wakeup capable before registering the class device, or the wakealarm attribute will not be created. Also make sure to unregister the wakeup source on probe errors. Fixes: 1d2e2b65 ("rtc: omap: restore back (hard-code) wakeup support") Signed-off-by:

This series fixes a few issues with the omap rtc-driver, cleans up a bit, adds device abstraction, and finally adds support for the PMIC control feature found in some revisions of this RTC IP block. Ultimately, this allows for powering off the Beaglebone and waking it up again on RTC alarms. This patch (of 20): Make sure not to reset the clock-source configuration when enabling the 32kHz clock mux. Until the clock source can be configured through device tree we must not overwrite settings made by the bootloader (e.g. clock-source selection). Fixes: cd914bba ("drivers/rtc/rtc-omap.c: add support for enabling 32khz clock") Signed-off-by:
