2014-03-04drivers/rtc/rtc-s3c.c: fix incorrect way of save/restore of S3C2410_TICNT ↵Vikas Sajjan1-5/+12
for TYPE_S3C64XX On exynos5250, exynos5420 and exynos5260 it was observed that, after 1 cycle of S2R, the rtc-tick occurs at a very fast rate as compared to the rtc-tick occuring before S2R. This patch fixes the above issue by correcting the wrong way of save/restore of S3C2410_TICNT for TYPE_S3C64XX.

2014-01-24drivers/rtc/rtc-rx8581.c: add SMBus-only adapters supportAndreas Werner1-13/+68
Add support for SMBus-only adapters (e.g. i2c-piix4). The driver has implemented only support for I2C adapters which implement the I2C_FUNC_SMBUS_I2C_BLOCK functionality before. With this patch it is possible to load and use the RTC driver with I2C and SMBUS adapters like the rtc-ds1307 does. Tested on AMD G Series Platform (i2c-piix4 adapter driver).

2014-01-24rtc: max8907: weekday encoding fixesStephen Warren1-6/+5
The current MAX8907 driver has two issues related to weekday value handling: 1) The HW WEEKDAY register has range 0..6 rather than 1..7 as documented. Note that I validated the actual HW range by observing the HW register roll from 6->0 rather than 6->7->1 as would otherwise be expected. This matches Linux's tm_wday range of 0..6. When the CMOS RAM content is lost, the date returned from the device is 2007-01-01 00:00:00, which is a Monday. The WEEKDAY register reads 1 in this case. This matches the numbering in Linux's tm_wday field. Hence we should write Linux's tm_wday value to the register without modifying it. Hence, remove the +1/-1 calculations for WEEKDAY/tm_wday. 2) There's no need to make alarms match on the WEEKDAY register, since the other fields together uniquely define the alarm date/time. Ignoring the WEEKDAY value in the match isolates the driver from any incorrect value in the current time copy of the WEEKDAY register. Each change individually, or both together, solves an issue that I observed; "hwclock -r" would time out waiting for its alarm to fire if the CMOS RAM content had been lost, and hence the WEEKDAY register value mismatched what the driver expected it to be. "hwclock -w" would solve this by over-writing the HW default WEEKDAY register value with what the driver expected.

2014-01-24rtc: honor device tree /alias entries when assigning IDsStephen Warren1-4/+20
Assign RTC device IDs based on device tree /aliases entries if present, falling back to the existing numbering scheme if there is no /aliases entry (which includes when the system isn't booted using DT), or there is a numbering conflict. This is useful in systems with multiple RTC devices, to ensure that the best RTC device is selected as /dev/rtc0, which provides the overall system time. For example, Tegra has an on-SoC RTC that is not battery backed, typically coupled with an off-SoC RTC that is battery backed. Only the latter is useful for populating the system time, yet the former is useful e.g. for wakeup timing, since the time is not lost when the system is sleeps.

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and add new regmap for RTC. On S5M8767A registers were not properly updated and read due to usage of the same regmap as the PMIC. This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.

2013-11-22ARM: drivers/rtc/rtc-at91rm9200.c: disable interrupts at shutdownJohan Hovold1-0/+9
Make sure RTC-interrupts are disabled at shutdown. As the RTC is generally powered by backup power (VDDBU), its interrupts are not disabled on wake-up, user, watchdog or software reset. This could cause troubles on other systems (e.g. older kernels) if an interrupt occurs before a handler has been installed at next boot. Let us be well-behaved and disable them on clean shutdowns at least (as do the RTT-based rtc-at91sam9 driver).

2013-11-17alpha: Reorganize rtc handlingRichard Henderson1-1/+9
Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem. The marvel platform requires that the rtc only be touched from the boot cpu. This had been partially implemented with hooks for get/set_rtc_time, but read/update_persistent_clock were not handled. Move the hooks from the machine_vec to a special rtc_class_ops struct. We had read_persistent_clock managing the epoch against which the rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time. This resulted in incorrect values when hwclock(8) gets involved. Allow the epoch to be set from the kernel command-line, overriding the autodetection, which is doomed to fail in 2020. Further, by implementing the rtc ioctl function, we can expose this epoch to userland. Elide the alarm functions that RTC_DRV_CMOS implements. This was highly questionable on Alpha, since the interrupt is used by the system timer. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-11-15drivers/rtc/rtc-hid-sensor-time.c: enable HID input processing earlyAlexander Holler1-0/+7
Enable the processing of HID input records before the RTC will be registered, in order to allow the RTC register function to read clock. Without doing that the clock can only be read after the probe function has finished.
