rtc: class: remove redundant assignment to variable err

2020-04-02T16:47:30Z

The variable err is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

rtc: class: avoid unnecessary lookup in hctosys

2020-03-24T21:48:04Z

rtc_hctosys is only called when the relevant RTC is found, avoid looking it up while we already have a pinter to the proper struct rtc_device. Link: https://lore.kernel.org/r/20200323213039.297458-1-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: class: support hctosys from modular RTC drivers

2020-03-23T20:14:34Z

Due to distribution constraints it may not be possible to statically compile the required RTC driver into the kernel. Expand RTC_HCTOSYS support to cover all RTC devices (statically compiled or not) by checking at the end of RTC device registration whether the time should be synced.

rtc: class: add debug message when registration fails

2019-08-20T19:44:45Z

Add a message when __rtc_register_device fails because rtc->ops is NULL. This may only happen when developing a new driver so use dev_dbg to avoid compiling it in by default.

rtc: core: correct trivial checkpatch warnings

2019-04-04T08:07:08Z

Correct trivial checkpatch warnings, mostly whitespace issues and unbalanced braces. Signed-off-by: Alexandre Belloni

rtc: convert core to SPDX identifier

2019-03-18T02:36:01Z

Use SPDX-License-Identifier instead of a verbose license text. Also fix the block comment alignment. Signed-off-by: Alexandre Belloni

rtc: class: reimplement devm_rtc_device_register

2018-12-18T21:53:32Z

Implement devm_rtc_device_register using devm_rtc_allocate_device and __rtc_register_device so there is only one path left to register rtc devices. Also mark it as deprecated so new drivers will hopefully use devm_rtc_allocate_device and rtc_register_device that are less race prone and allow avoiding the 2038, 2070, 2100 and 2106 bugs properly.

rtc: enforce rtc_timer_init private_data type

2018-12-18T21:53:29Z

All the remaining users of rtc_timers are passing the rtc_device as private data. Enforce that and rename private_data to rtc. Suggested-by: Arnd Bergmann Signed-off-by: Alexandre Belloni

rtc: class: remove devm_rtc_device_unregister

2018-11-12T22:14:10Z

devm_rtc_device_unregister is not used by any driver and should not be used by any new driver. Signed-off-by: Alexandre Belloni

rtc: unexport non devm managed registration

2018-09-13T13:43:05Z

Ensure the non managed version of the un/registration functions is not used anymore. No driver is using it anymore and they should not be necessary. Signed-off-by: Alexandre Belloni
