Subject: [PATCH v2 0/3] rtc: make st-lpc robust against y2038/2106 bug
Date: Mon, 19 Jun 2017 11:36:19 +0200	[thread overview]
Message-ID: <1497864982-29284-1-git-send-email-benjamin.gaignard@linaro.org> (raw)

On 32bits platforms "struct timeval" or "time_t" are using u32 to code the
date, this cause tools like "date" or "hwclock" failed even before setting
the RTC device if the date is superior to year 2038 (or 2106).

To avoid this problem I add one RTC test file which directly use RTC ioctl
to set and read RTC time and alarm values.
rtctest_setdate allow to set any date/time given in the command line.

On this version 2 I add check of problematics years in rtctest like suggest
by Alexandre.

Finally that had allowed me to test and fix rtc-st-lpc driver.
