compatible DT node to determine if RTC is supported. Skip read/write from
RTC device only when this node is present and status is "disabled". In all
other cases, proceed as before.
get_wallclock() and set_wallclock() are function pointers of platform_ops
which are initialized to mach_get_cmos_time() and mach_set_rtc_mmss()
at init time. Since adding a new platform to override these functions is
discouraged, so the only way is to modify RTC get/set functions.
So, my point is, instead of hacking two functions, perhaps better to avoid them
at all.
