The current rtc-pcf85063 driver only supports the PCF85063TP device.
Using the existing driver on a PCF85063A will result in the time being
set correctly into the RTC, but the RTC is held in the stopped state.
Therefore, the time will no longer advance and no error is indicated.
The PCF85063A device has a bigger memory map than the PCF85063TP.
The existing driver make use of an address rollover condition,
but the rollover point is different in the two devices.

As per code flow s3c_rtc_setfreq() will get called with rtc clock disabled
and in set_freq we perform h/w registers read/write, which results in a
kernel crash on exynos7 platform while probing rtc driver.
Below is code flow:
s3c_rtc_probe()
clk_prepare_enable(info->rtc_clk) // rtc clock enabled
s3c_rtc_gettime() // will enable clk if not done, and disable it upon exit
s3c_rtc_setfreq() //then this will be called with clk disabled
This patch take cares of such issue by adding s3c_rtc_{enable/disable}_clk in
s3c_rtc_setfreq().

On some QNAP NAS devices the rtc can wake the machine. Several people
noticed that once the machine was woken this way it fails to shut down.
That's because the driver fails to acknowledge the interrupt and so it
keeps active and restarts the machine immediatly after shutdown. See
https://bugs.debian.org/794266 for a bug report.
Doing this correctly requires to interpret the INT2 flag of the first read
of the STATUS1 register because this bit is cleared by read.
Note this is not maximally robust though because a pending irq isn't
detected when the STATUS1 register was already read (and so INT2 is not
set) but the irq was not disabled. But that is a hardware imposed problem
that cannot easily be fixed by software.

There were two deviations from the reference manual: you have to wait
half a second when POC is active and you might have to repeat
initialization when POC or BLD are still set after the sequence.
Note however that as POC and BLD are cleared by read the driver might
not be able to detect that a reset is necessary. I don't have a good
idea how to fix this.
Additionally report the value read from STATUS1 to the caller. This
prepares the next patch.

There are several issues fixed in this patch:
- When alarm isn't enabled, set .enabled to zero instead of returning
-EINVAL.
- Ignore how IRQ1 is configured when determining if IRQ2 is on.
- The three alarm registers have an enable flag which must be
evaluated.
- The chip always triggers when the seconds register gets 0.
Note that the rtc framework however doesn't handle the result correctly
because it doesn't check wday being initialized and so interprets an
alarm being set for 10:00 AM in three days as 10:00 AM tomorrow (or
today if that's not over yet).

The reset value of weekday is 0x1. This is wrong since
the reset values of the day/month/year make up to Jan 1 2001.
When computed weekday comes out to be Monday. On a scale
of 1-7(Sunday - Saturday) it should be 0x2. So we should not
be relying on the reset value.
Hence compute the wday using the current date/month/year values.
Check if reset wday is any different from the computed wday,
If different then set the wday which we computed using
date/month/year values.

For old style drivers, call a call to ioctl(..., RTC_ALM_SET, ...):
- char/ds1302.c will always return -EINVAL
- char/genrtc.c: will always return -EINVAL
- char/rtc.c will succeed regardless if IRQs are supported or not
- char/efirtc.c will always return -EINVAL
- input/misc/hp_sdc_rtc.c ... that ioctl code is a good lesson about
ifdefing code out and punting implementation ... and it will
always return -EINVAL
For new style rtc drivers, a call to ioctl(..., RTC_ALM_SET, ...) never
results in a call to __rtc_set_alarm, since struct rtc_wkalarm passed to
rtc_set_alarm has 'enabled' field set to 0. This means that
rtc->ops->set_alarm driver hook is never called in that ioctl. Since no
driver code interaction happens as a part of that call, using its
results to ascertain properties of the driver is not going to work. To
remedy this - use the result of RTC_AIE_ON to make the judgement.
This patch also changes ENOTTY to EINVAL as an error code value that
would tell us that IRQs are not supported. There are three reason for
this:
- As mentioned above old style driver never returns ENOTTY for this
ioctl
- In it's code __rtc_set_alarm() returns -EINVAL if rtc->ops->set_alarm
method is not provided by the driver, so one reason for change is to
be consistent with that code path.
- A call to ioctl(..., RTC_UIE_ON, ...) will result in a call to
rtc_update_irq_enable() and then __rtc_set_alarm(), which, if IRQs
are not supported by the driver, will result in a non-zero error
code. Returning ENOTTY in that case would:
a) Not be consistent with other codepaths of
rtc_update_irq_enable, for example the check of
rtc->uie_unsupported
b) Would break update IRQ emulation code since that codpath
expects EINVAL
c) Would break test's logic for feature support detection in
the case of RTC_UIE_ON ioctl

This patch fixes a RTC wakealarm issue, namely, the event fires during
hibernate and is not cleared from the list, causing hwclock to block.
The current enqueuing does not trigger an alarm if any expired timers
already exist on the timerqueue. This can occur when a RTC wake alarm
is used to wake a machine out of hibernate and the resumed state has
old expired timers that have not been removed from the timer queue.
This fix skips over any expired timers and triggers an alarm if there
are no pending timers on the timerqueue. Note that the skipped expired
timer will get reaped later on, so there is no need to clean it up
immediately.
The issue can be reproduced by putting a machine into hibernate and
waking it with the RTC wakealarm. Running the example RTC test program
from tools/testing/selftests/timers/rtctest.c after the hibernate will
block indefinitely. With the fix, it no longer blocks after the
hibernate resume.
