Yong Zhang 2f6e5f9458 drivers/rtc: remove IRQF_DISABLED
Since commit e58aa3d2d0 ("genirq: run irq handlers with interrupts
disabled") we run all interrupt handlers with interrupts disabled and we
even check and yell when an interrupt handler returns with interrupts
enabled - see commit b738a50a20 ("genirq: warn when handler enables
interrupts").

So now this flag is a NOOP and can be removed.

Venu Byravarasu 2778ebcc09 drivers/rtc/rtc-twl.c: return correct RTC event from ISR
Following changes are made as part of this change:

1. As TWL RTC supports periodic interrupt, the correct event should be
   RTC_PF instead of RTC_UF.

2. No need to initialize variable "events" to 0 & then OR it with the
   event values.  Hence fixing it.

Venu Byravarasu 94a339d016 drivers/rtc/rtc-twl.c: simplify RTC interrupt clearing
For clearing RTC interrupt, programming ALARM bit only is sufficient, as
all other bits are any way not affected by writing 0 to them.

Hence removed unwanted OR operation.

Venu Byravarasu f7439bcb74 drivers/rtc/rtc-twl.c: enable RTC irrespective of its prior state
As part of probe, before enabling RTC, RTC_CTRL register is read to check
if it is already running.  If RTC is used by kernel alone, then this read
is not required.  Even if RTC was enabled already by boot loader, setting
STOP_RTC bit again should not harm.  Hence removed unwanted read
operation.

Viresh Kumar ee6c54ca64 rtc/rtc-spear: call platform_set_drvdata() before registering rtc device
rtc_device_register() calls rtc-spear routines internally.  These
routines call dev_get_drvdata() to get struct spear_rtc_config.
Currently, platform_set_drvdata is called after rtc device is
registered.  This causes system to crash, as dev_get_drvdata returns
NULL.

For this we need to call platform_set_drvdata() before registering rtc
device.  This requires further cleanup, that leads to removal of
dev_set_drvdata on rtc->dev, which was just not required at all.

Also, we change the parameter to request_irq and pass pointer to config
instead of pointer to rtc struct.

This patch brings all above changes.

John Stultz 4a649903f9 rtc: Provide flag for rtc devices that don't support UIE
Richard Weinberger noticed that on some RTC hardware that
doesn't support UIE mode, due to coarse granular alarms
(like 1minute resolution), the current virtualized RTC
support doesn't properly error out when UIE is enabled.

Instead the current code queues an alarm for the next second,
but it won't fire until up to a miniute later.

This patch provides a generic way to flag this sort of hardware
and fixes the issue on the mpc5121 where Richard noticed the
problem.

Rabin Vincent 41c7f74242 rtc: Disable the alarm in the hardware (v2)
Currently, the RTC code does not disable the alarm in the hardware.

This means that after a sequence such as the one below (the files are in the
RTC sysfs), the box will boot up after 2 minutes even though we've
asked for the alarm to be turned off.

	# echo $((`cat since_epoch`)+120) > wakealarm
	# echo 0 > wakealarm
	# poweroff

Fix this by disabling the alarm when there are no timers to run.

The original version of this patch was reverted. This version
disables the irq directly instead of setting a disabled timer
in the future.

NeilBrown 5f9679d29c rtc: Expire alarms after the time is set. (v2)
If the alarm time programming in the rtc is ever in the past, it won't fire,
and any other alarm will be queued after it so they won't fire either.

So any time that the alarm might be in the past, we need to trigger
the irq handler to ensure the old alarm is cleared and the timer queue
is fully in the future.

This is done whenever the RTC clock is set.

This is the second revision of this patch, which was earlier reverted.
This version avoids the initialization problem, which is handled by
a different patch.

John Stultz bd729d72b4 rtc: Avoid setting alarm to a time in the past
In some cases at boot up, the RTC alarm may be set in the past,
but still have the enabled flag on. This was causing problems,
because we would then enqueue the alarm into the timerqueue,
but it would never fire. This would clog up the timerqueue
and keep other alarms from working.

The fix is to check the alarm against the current rtc time at
boot and avoid enqueueing the alarm if it is in the past.

without the following patches applied:

Russell King a0164a574a Revert "RTC: sa1100: support sa1100, pxa and mmp soc families"
This reverts commit 7cea00657d.

The sa1100 cleanups fatally broke the SA1100 RTC driver - the first
hint that something is wrong are these compiler warnings:

drivers/rtc/rtc-sa1100.c:42:1: warning: "RCNR" redefined
In file included from arch/arm/mach-sa1100/include/mach/hardware.h:73,

and the second problem, which is far more severe, are the different
register layouts, resulting in the wrong registers being read on
SA11x0 platforms.  This patch adds:

	#define RCNR           0x00    /* RTC Count Register */
	#define RTAR           0x04    /* RTC Alarm Register */
	#define RTSR           0x08    /* RTC Status Register */
	#define RTTR           0x0c    /* RTC Timer Trim Register */

but the SA11x0 registers are:

	#define RTAR            __REG(0x90010000)  /* RTC Alarm Reg. */
	#define RCNR            __REG(0x90010004)  /* RTC CouNt Reg. */
	#define RTTR            __REG(0x90010008)  /* RTC Trim Reg. */

Ben Hutchings e74a8f2edb drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-range
Commit f44f7f96a2 ("RTC: Initialize kernel state from RTC") introduced a
potential infinite loop.  If an alarm time contains a wildcard month and
an invalid day (> 31), or a wildcard year and an invalid month (>= 12),
the loop searching for the next matching date will never terminate.  Treat
the invalid values as wildcards.

 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

Linus Torvalds f423fc627b Revert "rtc: Expire alarms after the time is set."
This reverts commit 93b2ec0128.

The call to "schedule_work()" in rtc_initialize_alarm() happens too
early, and can cause oopses at bootup

Neil Brown explains why we do it:

  "If you set an alarm in the future, then shutdown and boot again after
   that time, then you will end up with a timer_queue node which is in
   the past.

   When this happens the queue gets stuck.  That entry-in-the-past won't
   get removed until and interrupt happens and an interrupt won't happen
   because the RTC only triggers an interrupt when the alarm is "now".

   So you'll find that e.g.  "hwclock" will always tell you that
   'select' timed out.

   So we force the interrupt work to happen at the start just in case."

and has a patch that convert it to do things in-process rather than with
the worker thread, but right now it's too late to play around with this,
so we just revert the patch that caused problems for now.

Linus Torvalds 157e8bf8b4 Revert "rtc: Disable the alarm in the hardware"
This reverts commit c0afabd3d5.

It causes failures on Toshiba laptops - instead of disabling the alarm,
it actually seems to enable it on the affected laptops, resulting in
(for example) the laptop powering on automatically five minutes after
shutdown.

There's a patch for it that appears to work for at least some people,
but it's too late to play around with this, so revert for now and try
again in the next merge window.

John Stultz c3b79770e5 rtc: m41t80: Workaround broken alarm functionality
The m41t80 driver can read and set the alarm, but it doesn't
seem to have a functional alarm irq.

This causes failures when the generic core sees alarm functions,
but then cannot use them properly for things like UIE mode.

Disabling the alarm functions allows proper error reporting,
and possible fallback to emulated modes. Once someone fixes
the alarm irq functionality, this can be restored.

NeilBrown 93b2ec0128 rtc: Expire alarms after the time is set.
If the alarm time programming in the rtc is ever in the past, it won't fire,
and any other alarm will be queued after it so they won't fire either.

So any time that the alarm might be in the past, we need to trigger
the irq handler to ensure the old alarm is cleared and the timer queue
is fully in the future.

This can happen:
 - when we first initialise the alarm
 - when we set the time in the rtc.

so follow both of these by scheduling the timer work function.

Arve Hjønnevåg 6a8943d9ec rtc: Fix some bugs that allowed accumulating time drift in suspend/resume
The current code checks if abs(delta_delta.tv_sec) is greater or
equal to two before it discards the old delta value, but this can
trigger at close to -1 seconds since -1.000000001 seconds is stored
as tv_sec -2 and tv_nsec 999999999 in a normalized timespec.

rtc_resume had an early return check if the rtc value had not changed
since rtc_suspend. This effectivly stops time for the duration of the
short sleep. Check if sleep_time is positive after all the adjustments
have been applied instead since this allows the old_system adjustment
in rtc_suspend to have an effect even for short sleep cycles.

Rabin Vincent c0afabd3d5 rtc: Disable the alarm in the hardware
Currently, the RTC code does not disable the alarm in the hardware.

This means that after a sequence such as the one below (the files are in the
RTC sysfs), the box will boot up after 2 minutes even though we've
asked for the alarm to be turned off.

	# echo $((`cat since_epoch`)+120) > wakealarm
	# echo 0 > wakealarm
	# poweroff

Fix this by disabling the alarm when there are no timers to run.

Feng Tang 57e6319dd6 vrtc: change its year offset from 1960 to 1972
Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.

Updated patch which adds a sanity check suggested by Mathias

This isn't a change in behaviour for systems, because 1972 is the one we
actually use. It's the old version in upstream which is out of sync with
all devices.
