The interrupt handler gets the driver data associated with the RTC
device and doesn't check it for validity.  This can cause a NULL pointer
being dereferenced when and interrupt fires before the driver data was
properly set up.

Fix this by setting the driver data earlier (before the interrupt is
requested).

driver, it has been tested and works on a Technologic Systems TS-7670

In particular seeing zero in eft->month is problematic, as it results in
-1 (converted to unsigned int, i.e.  yielding 0xffffffff) getting passed
to rtc_year_days(), where the value gets used as an array index
(normally resulting in a crash).  This was observed with the driver
enabled on x86 on some Fujitsu system (with possibly not up to date
firmware, but anyway).

Perhaps efi_read_alarm() should not fail if neither enabled nor pending
are set, but the returned time is invalid?

It is not true, of_match_ptr() macro makes of_device_id parameter unused
and this constant is declared with __maybe_unused attribute, so normally
this variable should be discarded by linker.  This patch revers this

Remove the code for initializing time if this is first boot.

The code for detecting first boot uses undocumented field RTC_TCON in
RTC_UDR_CON register.  According to S5M8767's datasheet this field is
reserved.  On S2MPS14 it is not documented at all.

On device first boot the registers will be initialized with reset value
(2000-01-01 00:00:00).

The code might work on S5M8763 but still this does not look like a task

When RTC CLKTRCTRL bit is configured in HW_AUTO, module goes to sleep in
IDLE state.

The Alarm SWakeup event can be used to wakeup the RTC when it is in IDLE
state.  In order to do so, the alarm needs to be set and enabled before
RTC enters the IDLE state.  Also the wakeup generation for alarm/timer
event needs to be set (bits [1:0] in RTC_IRQWAKEEN register).

Currently RTC_IRQWAKEEN bits are set only in suspend/resume paths.  With
this ALARM interrupts are not generated when it enters IDLE state.  So
programming the RTC_IRQWAKEEN bits when ever ALARM is set.

The rtc user must wait at least 1 sec between each time/calandar update
(see atmel's datasheet chapter "Updating Time/Calendar").

Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for
the at91_rtc_wait_upd_rdy event if the rtc is not ready.

This patch fixes a deadlock in an uninterruptible wait when the RTC is
updated more than once every second.  AFAICT the bug is here from the
beginning, but I think we should at least backport this fix to 3.10 and
the following longterm and stable releases.

Newer versions of OMAP RTC IP such as those found in AM335x and DRA7x
need an explicit enable of 32khz functional clock which ticks the RTC.

AM335x support was working so far because of settings done in U-Boot.
However, the DRA7x U-Boot does no such enable of 32khz clock and this
patch is need to get the RTC to work on DRA7x at least.  In general, it
is better to not depend on settings done in U-Boot.
