2021-02-06rtc: armada38x: depend on OFAlexandre Belloni1-0/+1
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.

2021-02-03rtc: zynqmp: depend on HAS_IOMEMDavid Gow1-1/+1
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.

2021-02-02rtc: mc146818: Dont test for bit 0-5 in Register DThomas Gleixner2-4/+4
The recent change to validate the RTC turned out to be overly tight. While it cures the problem on the reporters machine it breaks machines with Intel chipsets which use bit 0-5 of the D register. So check only for bit 6 being 0 which is the case on these Intel machines as well.

2021-02-02amba: Make the remove callback return voidUwe Kleine-König2-6/+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.

2021-01-27rtc: mc146818: Detect and handle broken RTCsThomas Gleixner2-0/+15
The recent fix for handling the UIP bit unearthed another issue in the RTC code. If the RTC is advertised but the readout is straight 0xFF because it's not available, the old code just proceeded with crappy values, but the new code hangs because it waits for the UIP bit to become low. Add a sanity check in the RTC CMOS probe function which reads the RTC_VALID register (Register D) which should have bit 0-6 cleared. If that's not the case then fail to register the CMOS. Add the same check to mc146818_get_time(), warn once when the condition is true and invalidate the rtc_time data.

2021-01-26rtc: pcf2127: Disable Power-On Reset OverridePhilipp Rosenberger1-0/+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.

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.

2021-01-25rtc: mrst: Remove driver for deprecated platformAndy Shevchenko3-534/+0
Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.
