drivers/rtc/rtc-stmp3xxx.c: provide timeout for potentially endless loop polling a HW bit

2013-08-14T00:57:48Z

It's always a bad idea to poll on HW bits without a timeout. The i.MX28 RTC can be easily brought into a state in which the RTC is not running (until after a power-on-reset) and thus the status bits which are polled in the driver won't ever change. This patch prevents the kernel from getting stuck in this case. Signed-off-by: Lothar Waßmann Acked-by: Wolfram Sang Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-twl.c: fix: rtcX/wakealarm attribute isn't created

2013-07-31T21:41:03Z

The device_init_wakeup() should be called before rtc_device_register(). Otherwise, sysfs "sys/class/rtc/rtcX/wakealarm" attribute will not be seen from User space. Signed-off-by: Grygorii Strashko Cc: Kevin Hilman Cc: Tony Lindgren Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Pull MFD update from Samuel Ortiz: "For the 3.11 merge we only have one new MFD driver for the Kontron PLD. But we also have: - Support for the TPS659038 PMIC from the palmas driver. - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver. - RTL8411B support from the rtsx driver. - More DT support for the Arizona, max8998, twl4030-power and the ti_am335x_tsadc drivers. - The SSBI driver move under MFD. - A conversion to the devm_* API for most of the MFD drivers. - The twl4030-power got split from twl-core into its own module. - A major ti_am335x_adc cleanup, leading to a proper DT support. - Our regular arizona and wm* updates and cleanups from the Wolfson folks. - A better error handling and initialization, and a regulator subdevice addition for the 88pm80x driver. - A bulk platform_set_drvdata() call removal that's no longer need since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") * tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (102 commits) mfd: sec: Provide max_register to regmap mfd: wm8994: Remove duplicate check for active JACKDET MAINTAINERS: Add include directory to MFD file patterns mfd: sec: Remove fields not used since regmap conversion watchdog: Kontron PLD watchdog timer driver mfd: max8998: Add support for Device Tree regulator: max8998: Use arrays for specifying voltages in platform data mfd: max8998: Add irq domain support regulator: palmas: Add TPS659038 support mfd: Kontron PLD mfd driver mfd: palmas: Add TPS659038 PMIC support mfd: palmas: Add SMPS10_BOOST feature mfd: palmas: Check if irq is valid mfd: lpc_ich: iTCO_wdt patch for Intel Coleto Creek DeviceIDs mfd: twl-core: Change TWL6025 references to TWL6032 mfd: davinci_voicecodec: Fix build breakage mfd: vexpress: Make the driver optional for arm and arm64 mfd: htc-egpio: Use devm_ioremap_nocache() instead of ioremap_nocache() mfd: davinci_voicecodec: Convert to use devm_* APIs mfd: twl4030-power: Fix relocking on error ...

drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVI

2013-07-03T23:08:01Z

On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider (RTC_DIV) that divides the input 32.768KHz clock to the frequency that users need (E.g. 1 Hz). The divided real-time clock will be used to drive a 32-bit counter (RTC_COUNTER) that provides users with the actual time. In each cycle of the divided real-time clock, there is a Hertz interrupt generated to the RISC. Users can also configure an alarm (RTC_ALARM). When RTC_COUNTER matches the alarm, there will be an alarm interrupt generated to the RISC. The system RTC can generate an alarm wake-up signal to notify the power controller to wake up from power saving mode.

rtc: omap: restore back (hard-code) wakeup support

2013-07-03T23:08:00Z

rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms. However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry.

drivers/rtc/class: convert from Legacy pm ops to dev_pm_ops

2013-07-03T23:08:00Z

Convert drivers/rtc/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, rtc class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the rtc class.
