* [rtc-linux] [PATCH 28/51] rtc: jz4740: stop using rtc deprecated functions

rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.
For the same reasons use set_mmss64 callback instead of set_mmss

* [rtc-linux] [PATCH 35/51] rtc: pm8xxx: stop using rtc deprecated functions
From: Benjamin Gaignard @ 2017-06-20 9:35 UTC (permalink / raw)
To: benjamin.gaignard
Cc: linaro-kernel, Alessandro Zummo, Alexandre Belloni, rtc-linux,
linux-kernel
In-Reply-To: <1497951359-13334-1-git-send-email-benjamin.gaignard@linaro.org>
rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.

* [rtc-linux] [PATCH 41/51] rtc: stk17ta8: stop using rtc deprecated functions
From: Benjamin Gaignard @ 2017-06-20 9:35 UTC (permalink / raw)
To: benjamin.gaignard
Cc: linaro-kernel, Alessandro Zummo, Alexandre Belloni, rtc-linux,
linux-kernel
In-Reply-To: <1497951359-13334-1-git-send-email-benjamin.gaignard@linaro.org>
rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.

rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.
For the same reasons use set_mmss64 callback instead of set_mmss
Since only set_mmss64 be will used remove module parameter.

rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.

Please don't, because this hide the fact that the hardware will not
handle dates in y2038 anyway and as pointed by Russell a few month ago,
rtc_time_to_tm will be able to catch it but the 64 bit version will
silently ignore it.
