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. Fixes: 09ef18bc ("rtc: use devm_platform_ioremap_resource() to simplify code") Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

Introduce a bitfield to allow the drivers to announce the available features for an RTC. The main use case would be to better handle alarms, that could be present or not or have a minute resolution or may need a correct week day to be set. Use the newly introduced RTC_FEATURE_ALARM bit to then test whether alarms are available instead of relying on the presence of ops->set_alarm. Signed-off-by:
