rtc: rs5c372: Fix reading from rtc when the oscillator got interrupted.

2019-02-11T08:41:21+00:00

When the oscillator of the rtc gets interrupted,
e.g. due to an empty battery, reading from the rtc will now return an error
and the oscillator bit will be cleared, once the rtc is successfully reset.

rtc: rs5c372: r2221: fix to use the correct XSTP bit

2019-02-05T22:11:31+00:00

The Ricoh chips have slightly different register layouts
and the r2221 chip uses bit 5 as the oscillator halt sensor bit.

rtc: rs5c372: remove useless indirection

2018-03-17T13:20:45+00:00

rs5c372_get_datetime and rs5c372_set_datetime are only used after casting
dev to an i2c_client. Remove that useless indirection.

rtc: rs5c372: stop validating rtc_time in .read_time

2018-03-17T13:20:45+00:00

The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it before returning from the callback.

rtc: rs5c372: remove useless message

2018-03-17T13:20:44+00:00

It is not necessary to print a message when the time is invalid as
userspace will already get an error (and an optional dev_dbg message).

rtc: rs5c372: Add OF device ID table

2017-03-09T00:29:34+00:00

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

rtc: simplify implementations of read_alarm

2016-07-09T08:24:45+00:00

Since commit d68778b80dd7 ("rtc: initialize output parameter for read
alarm to "uninitialized"") there is no need to explicitly set
unsupported members to -1. So drop the respective assignments from
drivers.

rtc: rs5c372: r2025: fix check for 'oscillator halted' condition

2016-05-21T15:07:16+00:00

The R2025SD chip, according to its data sheet, sets the /XST
bit to zero if the oscillator stops. Hence the check for this
condition was wrong.

rtc: Use IS_ENABLED() instead of checking for built-in or module

2016-05-20T10:33:51+00:00

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.
