2011-05-02RTC: Disable CONFIG_RTC_CLASS from being built as a moduleJohn Stultz1-5/+2
The RTC subsystem has a number of accessors that are available via include/linux/rtc.h. However many of these interfaces are not available for use if CONFIG_RTC_CLASS=m. So in order to support wider use of the RTC in the kernel, I'm removing the tristate config option for a bool, so that code can easily be conditionalized if the RTC class is present or not.

We call rtc_read_alarm from rtc_device_register, so it is important that the rtc device is fully initialized prior to registration. rtc-max8925 sets drvdata after register, so the rtc_read_alarm code dereferences a NULL pointer. Call dev_set_drvdata before rtc_device_register.

2011-04-26time: Add timekeeping_inject_sleeptimeJohn Stultz1-14/+9
Some platforms cannot implement read_persistent_clock, as their RTC devices are only accessible when interrupts are enabled. This keeps them from being used by the timekeeping code on resume to measure the time in suspend. The RTC layer tries to work around this, by calling do_settimeofday on resume after irqs are reenabled to set the time properly. However, this only corrects CLOCK_REALTIME, and does not properly adjust the sleep time value. This causes btime in /proc/stat to be incorrect as well as making the new CLOCK_BOTTTIME inaccurate. This patch resolves the issue by introducing a new timekeeping hook to allow the RTC layer to inject the sleep time on resume. The code also checks to make sure that read_persistent_clock is nonfunctional before setting the sleep time, so that should the RTC's HCTOSYS option be configured in on a system that does support read_persistent_clock we will not increase the total_sleep_time twice.

2011-04-07rtc, x86/mrst/vrtc: Fix boot crash in rtc_read_alarm()Feng Tang1-3/+4
Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") caused a boot regression on the MRST platform. The reason is that rtc_device_register() calls rtc_read_alarm() after that change, which function does not have all driver data set up yet. The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register() gets called.

2011-03-29RTC: Fix early irqs caused by calling rtc_set_alarm too earlyJohn Stultz2-1/+27
When we register an rtc device at boot, we read the alarm value in hardware and set the rtc device's aie_timer to that value. The initial method to do this was to simply call rtc_set_alarm() with the value read from hardware. However, this may cause problems as rtc_set_alarm may enable interupts, and the RTC alarm might fire, which can cause invalid pointer dereferencing since the RTC registration is not complete. This patch solves the issue by initializing the rtc_device.aie_timer y hand via rtc_initialize_alarm(). This avoids any calls to the RTC hardware which might enable interrupts too early.
