The driver will compile with warning without OF because armada38x_data and
armada8k_data will be defined but not used. It would be possible to move
then in the #ifdef CONFIG_OF section but then their members will be defined
but not used. Instead of moving most of the driver in the #ifdef, simply
depend on OF.

rtc: rv3028: fix PORF handling · f007c479

Alexandre Belloni authored Jan 26, 2021

The PORF bit is cleared on interrupts which prevents the driver to know
when the time and date are invalid. Stop clearing PORF in the interrupt
handler.

It is redundant to do irqsave and irqrestore in hardIRQ context, where
it has been in a irq-disabled context.

rtc: zynqmp: depend on HAS_IOMEM · ddd05215

David Gow authored Jan 26, 2021

The Xilinx zynqmp RTC driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver not to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

rtc: pcf2127: Run a OTP refresh if not done before · 15f57b3e

Philipp Rosenberger authored Jan 18, 2021

The datasheet of the PCF2127 states, it is recommended to process an OTP
refresh once the power is up and the oscillator is operating stable. The
OTP refresh takes less than 100 ms to complete.

rtc: pcf2127: Disable Power-On Reset Override · b9ac079a

Philipp Rosenberger authored Jan 18, 2021

To resume normal operation after a total power loss (no or empty
battery) the "Power-On Reset Override (PORO)" facility needs to be
disabled.

The register reset value sets the PORO enabled and the data sheet
recommends setting it to disabled for normal operation.

From what I've seen on the PCF2127 and PCF2129 there is no event
generated at the interrupt pin (INT), as long the PORO bit is set. This
behavior is not documented in the manual.

rtc: tps65910: Support wakeup-source property · 454ba154

Dmitry Osipenko authored Jan 21, 2021

TPS65910 is a PMIC MFD device and RTC is one of its functions. The
wakeup-source DT property is specified for the parent MFD device and we
need to use this property for the RTC in order to allow to use RTC alarm
for waking up system from suspend by default, instead of requiring user
to enable wakeup manually via sysfs.
