Subject: [ARM] pxa: stop doing our own rtc management over suspend
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2aca0a865722fce435034cee5a33e1726fe10a9f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[ARM] pxa: stop doing our own rtc management over suspend

Remove the RTC management over a suspend/resume cycle.  Firstly,
we may not be using the internal RTC for time keeping; some
platforms have an external RTC for this inspite of the PXA having
an internal RTC.  Secondly, the RTC library code handles updating
system time on resume.
