The 32k clocksource is never used, because it is always registered at the same time as the us clocksource, which has a higher rating. Using the 32k clocksource would cause a race condition with the tegra_rtc driver on the RTC shadow registers. Remove the 32k clocksource, add a replacement tegra_read_rtc_ms function for the suspend code to track suspend time, and add a comment on read_persistent_clock that it should never be called while the tegra_rtc driver is running. It is currently only called from timekeeping init, suspend, and resume. Change-Id: Ic964578e9923b0f0338959f75de1ac170f850337 Signed-off-by: Colin Cross <ccross@android.com>
