c8ae2735cb rtc: isl12022: Drop unneeded OF guards and of_match_ptr() 
Drop unneeded OF guards and of_match_ptr(). This allows use of

.read_alarm is not necessary to read the current alarm because it is
recorded in the aie_timer and so rtc_read_alarm() will never call

5ddfa148de rtc: jz4740: Register clock provider for the CLK32K pin 
On JZ4770 and JZ4780, the CLK32K pin is configurable. By default, it is
configured as a GPIO in input mode, and its value can be read through
GPIO PD14.

With this change, clients can now request the 32 kHz clock on the CLK32K
pin, through Device Tree. This clock is simply a pass-through of the
input oscillator's clock with enable/disable operations.

This will permit the WiFi/Bluetooth chip to work on the MIPS CI20 board,
which does source one of its clocks from the CLK32K pin.

Since commit c8d523a4b0 ("drivers/rtc/rtc-pm8xxx.c: rework to support
pm8941 rtc") which removed the shadow control register there is no need
for a driver lock.

Specifically, the rtc ops are serialised by rtc core and the interrupt
handler only unconditionally disables the alarm using the alarm_ctrl
register.

Note that since only the alarm enable bit of alarm_ctrl is used after
enabling the RTC at probe, the locking was not needed when doing open
coded read-modify-write cycles either.

e5c594233f rtc: rv8803: invalidate date/time if alarm time is invalid 
RTC core never calls rv8803_set_alarm with an invalid alarm time,
so if an invalid alarm time > 0 is set, external factors must have
corrupted the RTC's alarm time and possibly other registers.

Play it safe by marking the date/time invalid, so all registers are
reinitialized on a ->set_time.

This may cause existing setups to lose time if they so far set only
date/time, but ignored that the alarm registers had an invalid date
value, e.g.:

  rtc rtc0: invalid alarm value: 2020-3-27 7:82:0

These systems will have their ->get_time return -EINVAL till
->set_time initializes the alarm value (and sets a new time).

24304a8715 rtc: brcmstb-waketimer: allow use as non-wake alarm 
The wake interrupt only fires when the system is in a suspend
state. Fortunately we have another interrupt that fires in a
non-suspend state at the L2 controller UPG_AUX_AON. Add support
for this interrupt line so we can use the alarm in a non-wake
context.

344f4030f6 rtc: sun6i: Always export the internal oscillator 
On all variants of the hardware, the internal oscillator is one possible
parent for the AR100 clock. It needs to be exported so we can model that
relationship correctly in the devicetree.

Fixes: c56afc1844 ("rtc: sun6i: Expose internal oscillator through device tree")
