When entering suspend while an wakeup alarm is set, enable_set_wake
should make sure that the RTC interrupt keep being enabled and the
.irq_set_wake for the RTC interrupt get called. However, since the
driver uses the suspend_noirq callback, the call to enable_irq_wake
has been made after disabling the interrupts. While .irq_set_wake
has been called properly, the interrupt remained disabled.
Use the suspend callback to call enable_irq_wake early enough to
ensure the RTC interrupt remains enabled.

Using gpio_request_array()/gpio_free_array() can make the code
simpler because it can set the direction and initial value
in one shot and the for loop is unnecessary.
Also, struct v3020_gpio is removed, because the struct v3020_gpio
is replaced with struct gpio.

On some !ARM 32bits platforms, the following compilation error happens
because of the division on a 64bits value in mtk_rtc_read_time():

According to C99, %2.s means 'print two spaces' (a precision of
. without following digits or * means 0). The kernel's printf
implementation, however, treats that case as if no precision was
given, but relying on that quirk is rather silly. Also, since no -
(aka left-justify) flag is given, the field with of 2 would then cause
the alarm->enabled case to come out as "o n". Deobfuscate it.

Currently, code of Loongson-2/3 is under loongson directory and code of
Loongson-1 is under loongson1 directory. Besides, there are Kconfig
options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is
very ugly and confusing. Since Loongson-2/3 are both 64-bit general-
purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names
and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

While setting the time, the RTC TIME register should not be accessed.
However due to hardware constraints, setting the RTC time involves
sleeping during 100ms. This sleep was done outside the critical section
protected by the spinlock, so it was possible to read the RTC TIME
register and get an incorrect value. This patch introduces a mutex for
protecting the RTC TIME access, unlike the spinlock it is allowed to
sleep in a critical section protected by a mutex.
The RTC STATUS register can still be used from the interrupt handler but
it has no effect on setting the time.

The RTC driver supports two flavors of S5M devices: S5M8767-like and
S2MPS14-like.
On S2MPS13 and S2MPS14 devices the RTC module is the same so we want to
re-use the existing support of S2MPS14. However device type was passed
from parent MFD driver in platform data structure. This way for the
S2MPS13 device the main MFD driver passed device type of 'S2MPS13X'.
Instead decouple detecting of device type between main MFD and RTC driver.
This allows adding support for other S2MPS14 variations (like S2MPS11 and
S2MPS13) easily by adding to mfd/sec-core.c:
static const struct mfd_cell s2mps13_devs[] = {
{ .name = "s2mps14-rtc", }
};

The hym8563 datasheet describes the clock output control-bit as "when set
to logic 0, the square wave output is enable, when set to logic 1, the
CLKOUT output is inhibited". But in reality the setting is exactly
opposite.
Before now, the clock output was not really used, but on the rk3288 soc
this generated clock is used to supply the temperature sensor block and
the swapped bit value prevented it from working. With the corrected
value, the tsadc now reports correct values.

register writes
RTC module contains a kicker mechanism to prevent any spurious writes from
changing the register values. This mechanism requires two MMR writes to
the KICK0 and KICK1 registers with exact data values before the kicker
lock mechanism is released.
Currently the driver release the lock in the probe and leaves it enabled
until the rtc driver removal. This eliminates the idea of preventing
spurious writes when RTC driver is loaded. So implement rtc lock and
unlock functions before and after register writes.
This is as advised by Paul to implement lock and unlock functions in the
driver and not to unlock and leave it in probe. The same discussion can
be seen here:

__rtc_read_time logs should be debug logs instead of error logs.
For example, when the RTC clock is not set, it's not really useful
to print a kernel error log every time someone tries to read the clock:
~ # hwclock -r
[ 604.508263] rtc rtc0: read_time: fail to read
hwclock: RTC_RD_TIME: Invalid argument
If there's a real error, it's likely that lower level or higher level
code will tell it anyway. Make these logs debug logs, and also print
the error code for the read failure.

When the clock is disabled, do not return a rate of 0 but instead return
the rate the clock will be running at after it gets enabled. This
prevents problems when the core clock code is trying to determine a
suitable rate, while the clock is still off.

partially updated values
The RTC is in a different clock domain so a quick read after write
can retrieve a mangled value of the old/new values
