2021-04-29rtc: omap: use rtc_write to access OMAP_RTC_OSC_REGDario Binacchi1-3/+2
The RTC_OSC_REG register is 32-bit, but the useful information is found in the 7 least significant bits (bits 7-31 are reserved). And in fact, as you can see from the code, all read accesses are 8-bit, as well as some writes. Let's make sure all writes are 8-bit. Moreover, in contexts where consecutive reads / writes after the busy check must take place within 15 us, it is better not to waste time on useless accesses.

2021-04-29rtc: rtc_update_irq_enable: rework UIE emulationAlexandre Belloni1-24/+10
Now that the core is aware of whether alarms are available, it is possible to decide whether UIE emulation is required before actually trying to set the alarm. This greatly simplifies rtc_update_irq_enable because there is now only one error value to track and is not relying on the return value of __rtc_set_alarm anymore.

2021-04-16rtc: pcf85063: fallback to parent of_nodeFrancois Gervais1-4/+3
The rtc device node is always NULL. Since v5.12-rc1-dontuse/3c9ea42802a1fbf7ef29660ff8c6e526c58114f6 this will lead to a NULL pointer dereference. To fix this use the parent node which is the i2c client node as set by devm_rtc_allocate_device(). Using the i2c client node seems to be what other similar drivers do e.g. rtc-pcf8563.c.

2021-02-13rtc: abx80x: Add utility function for writing configuration keyKevin P. Fleming1-23/+16
Writing one of key two values into the configuration key register is a common operation, so a utility function has been added to provide consistent behavior and eliminate code duplication.

2021-02-06rtc: s3c: stop setting bogus timeAlexandre Belloni1-15/+0
It doesn't make sense to set the RTC to a default value at probe time. Let the core handle invalid date and time. Also, this is basically dead code since commit 22652ba72453 ("rtc: stop validating rtc_time in .read_time") Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20210202112934.3612726-1-alexandre.belloni@bootlin.com
