2015-09-05rtc: bq32k: remove redundant checkManinder Singh1-1/+1
removing below static analysis error: (error) Possible null pointer dereference: client if (!i2c_check_functionality(client->adapter, I2C_FUNC_I2C)) ^^^^^^^ Error comes because client is dereferenced before NULL check.

Use module_platform_driver for drivers whose init and exit functions only register and unregister, respectively.

2015-09-05rtc: ds1307: Support optional wakeup interrupt sourceNishanth Menon1-3/+33
With the recent pinctrl-single changes, SoCs such as Texas Instrument's OMAP processors can treat wake-up events from deeper idle states as interrupts. Let's add support for the optional second interrupt for wake-up using the generic wakeirq support added in commit 4990d4fe327b ("PM / Wakeirq: Add automated device wake IRQ handling") Finally, to pass the wake-up interrupt in the dts file, interrupts-extended property needs to be passed. This is similar in approach to commit 2a0b965cfb6e ("serial: omap: Add support for optional wake-up") + ee83bd3b6483 ("serial: omap: Switch wake-up interrupt to generic wakeirq") Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

And all of them really didn't do anything with that information as the system or module was shutting down no matter what.

2015-06-25rtc: ds1307: Enable the mcp794xx alarm after programming timeNishanth Menon1-6/+6
Alarm interrupt enable register is at offset 0x7, while the time registers for the alarm follow that. When we program Alarm interrupt enable prior to programming the time, it is possible that previous time value could be close or match at the time of alarm enable resulting in interrupt trigger which is unexpected (and does not match the time we expect it to trigger). To prevent this scenario from occuring, program the ALM0_EN bit only after the alarm time is appropriately programmed. Ofcourse, I2C programming is non-atomic, so there are loopholes where the interrupt wont trigger if the time requested is in the past at the time of programming the ALM0_EN bit. However, we will not have unexpected interrupts while the time is programmed after the interrupt are enabled.

2015-06-25rtc: efi: use correct EFI 'epoch'Ard Biesheuvel1-25/+14
The rtc-efi driver declares that the EFI 'epoch' is 1/1/1998, but the UEFI spec does not define it at all. It does define a range of [1900, 9999] for the 'Year' member of the EFI_TIME struct, so let's use 1900 as the minimum year and not 1998. Also, move the validation of the year to the convert_from_efi_time() routine where all other EFI_TIME fields are validated as well. This prevents rtc_read_time() failures when the RTC that backs the EFI time services is set to a date before 1998, e.g., when it has lost power. This also optimizes the compute_wday() routine, by replacing the for loop with a simple arithmetic expression, and by reusing the yearday value that we need to compute anyway when populating the rtc_time::tm_yday field.

2015-06-25rtc: snvs: fix wakealarm by call enable_irq_wake earlierStefan Agner1-9/+21
When entering suspend while an wakeup alarm is set, enable_set_wake should make sure that the RTC interrupt keep being enabled and the .irq_set_wake for the RTC interrupt get called. However, since the driver uses the suspend_noirq callback, the call to enable_irq_wake has been made after disabling the interrupts. While .irq_set_wake has been called properly, the interrupt remained disabled. Use the suspend callback to call enable_irq_wake early enough to ensure the RTC interrupt remains enabled.

2015-06-25rtc: rtc-v3020: use gpio_request_array()Jingoo Han1-30/+11
Using gpio_request_array()/gpio_free_array() can make the code simpler because it can set the direction and initial value in one shot and the for loop is unnecessary. Also, struct v3020_gpio is removed, because the struct v3020_gpio is replaced with struct gpio.

2015-06-25rtc: mc13xxx: fix obfuscated and wrong format stringRasmus Villemoes1-1/+1
According to C99, %2.s means 'print two spaces' (a precision of . without following digits or * means 0). The kernel's printf implementation, however, treats that case as if no precision was given, but relying on that quirk is rather silly. Also, since no - (aka left-justify) flag is given, the field with of 2 would then cause the alarm->enabled case to come out as "o n". Deobfuscate it.
