rtc: tps65910: allow using RTC without alarm interrupt

2019-11-17T21:24:33+00:00

If tps65910 INT1 pin (IRQ output) is not wired to any IRQ controller,
then it can't be used as system wakeup/alarm source,
but it is still possible to read/write time from/to RTC.

rtc: remove superfluous error message

2019-08-21T07:57:23+00:00

The RTC core now has error messages in case of registration failure, there
is no need to have other messages in the drivers.

rtc: tps65910: fix typo in register name in read_alarm()

2019-06-01T21:13:10+00:00

Fix an obvious typo: in read_alarm() call we should read alarm setting
(starting at ALARM_SECONDS register) and not current time.

rtc: tps65910: allow platform power up

2018-05-17T20:37:09+00:00

Currently, the IRQs are disabled when the rtc driver is removed (e.g. when
shutting down the platform).
This means that the RTC will be unable to power up the platform.

rtc: tps65910: fix possible race condition

2018-05-17T20:37:07+00:00

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.

Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before requesting the IRQ.

Texas Instrument's TPS65910 has support for compensating RTC crystal
inaccuracies. When enabled every hour RTC counter value will be compensated
with two's complement value.
