* rtc: simplify devm_request_mem_region/devm_ioremapJulia Lawall2013-09-119-107/+37
| | | | | | | | | | | | | | | | | | | | Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bios may clear the rtc control register when resuming the system. Since the cmos interrupt handler may now be run before the rtc_cmos is resumed, this can cause the interrupt handler to ignore an alarm since the alarm bit is not set in the rtc control register. To work around this, check if the rtc_cmos is suspended and use the stored value for the rtc control register.

* | drivers/rtc/rtc-twl.c: ensure IRQ is wakeup enabledKevin Hilman2013-07-031-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the RTC IRQ is never wakeup-enabled so is not capable of bringing the system out of suspend. On OMAP platforms, we have gotten by without this because the TWL RTC is on an I2C-connected chip which is capable of waking up the OMAP via the IO ring when the OMAP is in low-power states. However, if the OMAP suspends without hitting the low-power states (and the IO ring is not enabled), RTC wakeups will not work because the IRQ is not wakeup enabled. To fix, ensure the RTC IRQ is wakeup enabled whenever the RTC alarm is set.
