arm64: tegra: Add RTC support on Tegra194 (37e5a31d) · Commits · 戴 / test

The RTC on Tegra194 is very similar to the RTC on earlier generations. One notable exception is that the source clock is now the 32 kHz clock instead of a dedicated RTC clock and the RTC alarm is a wake event and can be used to wake the system from sleep. Signed-off-by:
