| * | amba: Make the remove callback return voidUwe Kleine-König2021-02-022-6/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 OverridePhilipp Rosenberger2021-01-261-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 propertyDmitry Osipenko2021-01-251-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
