BD71815 contains similar RTC block as BD71828. Only the address offsets seem different. Support also BD71815 RTC using rtc-bd70528.

2021-04-14rtc: bd70528: Do not require parent dataMatti Vaittinen1-36/+31
The ROHM BD71828 and BD71815 RTC drivers only need the regmap pointer from parent. Regmap can be obtained via dev_get_regmap() so do not require parent to populate driver data for that. BD70528 on the other hand requires parent data to access the watchdog so leave the parent data for BD70528 here for now.

2021-03-11iio: hid-sensors: Move get sensitivity attribute to hid-sensor-commonYe Xiang1-1/+3
No functional change has been made with this patch. The main intent here is to reduce code repetition of getting sensitivity attribute. In the current implementation, sensor_hub_input_get_attribute_info() is called from multiple drivers to get attribute info for sensitivity field. Moving this to common place will avoid code repetition.

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.
