The chip_desc table is suboptimal. Currently it requires an entry for
every new chip type, even if it is empty. This has already been
forgotten for the ds1388. Refactor the code, so new entries are only
needed, when they chip type really needs a (non-empty) description.
Also make the table visually more appealing.

Since commit e58aa3d2d0cc ("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 b738a50a2026 ("genirq: warn when handler enables
interrupts").
So now this flag is a NOOP and can be removed.

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.

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.

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.

For simple modules that contain a single amba_driver without any

If probing the RTC didn't succeed due to failed RTC register access, the

r9701_remove() causes a kernel crash while trying to unregister a not

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.

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.

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.

This wasn't tested as a stand-alone patch, and it has build errors
without the following patches applied:
drivers/rtc/rtc-sa1100.c: In function 'sa1100_rtc_set_alarm':
drivers/rtc/rtc-sa1100.c:208: error: 'now' undeclared (first use in this function)

So it too gets reverted to bring us back to a working point.

This reverts commit 7cea00657dd4daef66ad95e976d5d67ed94cb97e.
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

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. */
#define RTSR __REG(0x90010010) /* RTC Status Reg. */

Commit f44f7f96a20a ("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 patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

The rtc_calibration attribute allows user-space to get and set the
AB8500's RtcCalibration register. The AB8500 will then use the value in
this register to compensate for RTC drift every 60 seconds.

The resolution of msleep is related to HZ, so with HZ set to 100 any
msleep of less than 10ms will become ~10ms. This is not what we want.
Use the hrtimer-based usleep_range() and allow for some slack in the
non-critical path so we have more control of what is happening here.

There is no way to track year in the i.MX1 RTC: Days Counter register is
9-bit wide only. Attempt to save date after 1970-01-01 plus 512 days
causes endless loop in mxc_rtc_set_mmss(). Fix this by resetting year to
1970.

The patch renames puv3_rtcdrv to puv3_rtc_driver, so that modpost will know
that this is simply a list of pointers to driver functions, in which case
the section mismatch is OK. (Thanks Michal Marek)
