2020-11-19rtc: rework rtc_register_device() resource managementBartosz Golaszewski
rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

2020-03-23rtc: bd70528: Avoid double error messaging when IRQ absentKeyur Patel
Since the commit 7723f4c ("driver core: platform: Add an error message to platform_get_irq*()") platform_get_irq() started issuing an error message. Thus, there is no need to have the same in the driver.

2020-01-24rtc: bd70528: add BD71828 supportMatti Vaittinen
ROHM BD71828 PMIC RTC block is from many parts similar to one on BD70528. Support BD71828 RTC using BD70528 RTC driver and avoid re-inventing the wheel.

2019-11-08rtc: bd70528: Add MODULE ALIAS to autoload moduleMatti Vaittinen
The bd70528 RTC driver is probed by MFD driver. Add MODULE_ALIAS in order to allow udev to load the module when MFD sub-device cell for RTC is added. I'm not sure if this is a bugfix or feature addition but I guess fixes tag won't harm in this case.

The RTC core now has error messages in case of registration failure, there is no need to have other messages in the drivers.

2019-08-13rtc: Remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-06-27rtc: bd70528: Initial support for ROHM bd70528 RTCMatti Vaittinen
Support RTC block in ROHM bd70528 power management IC. Support getting and setting the time and date as well as arming an alarm which can also be used to wake the PMIC from standby state. HW supports wake interrupt only for the next 24 hours (sec, minute and hour information only) so we limit also the alarm interrupt to this 24 hours for the sake of consistency.
