The RV1805 uses smaller package than the AB1805, discern those two
chips based on the compatible value and configure reserved bits in
the RV1805 to prevent current leakage and accidental test mode entry.Signed-off-by: Marek Vasut

There is a race condition that can happen if abx80x_probe() fails after the
rtc registration succeeded. Solve that by moving the registration at the

If devm_add_action() fails we are explicitly calling the cleanup to free
the resources allocated. Lets use the helper devm_add_action_or_reset()
and return directly in case of error, as we know that the cleanup function
has been already called by the helper if there was any error.Signed-off-by: Sudip Mukherjee

Handle the Oscillator Failure ('OF') bit from Oscillator Status register
(0x1D). This bit is cleared on set_time function and is read each time the
date/time is read, but only in case of XT Oscillator selection.
In RC mode, this bit is always set.Signed-off-by: Mylène Josserand

The autocalibration is separated in two bits to set in Oscillator
Control register (0x1c) :
- OSEL bit to select the oscillator type (XT or RC).
- ACAL bit to select the autocalibration type.These functionnalities are exported in sysfs entries : "oscillator"
and "autocalibration". Respectively, the values are "xtal" for XT
oscillator and "rc" for RC oscillator and 0 to disable the
autocalibration cycle, 512 for a 512 seconds autocalibration cycle
and 1024 for a cycle of 1024 seconds.Examples :
Set to XT Oscillator
echo xtal > /sys/class/rtc/rtc0/device/oscillator
Activate an autocalibration every 512 seconds
echo 512 > /sys/class/rtc/rtc0/device/autocalibrationSigned-off-by: Mylène Josserand

This is a basic driver for the ultra-low-power Abracon AB x80x series of RTC
chips. It supports in particular, the supersets AB0805 and AB1805.
It allows reading and writing the time, and enables the supercapacitor/
battery charger.[arnd@arndb.de: abx805 depends on i2c]
