time: workaround for FRC_TIMER_INT_REG write issue In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus. Writing to another DPORT register immediately before or after that works around the issue. We write one dummy value to an address which doesn’t have any register associated with it. Fixes https://github.com/espressif/arduino-esp32/issues/120

unity: separate common and IDF specific functionality New unity component can be used for testing other applications. Upstream version of Unity is included as a submodule. Utilities specific to ESP-IDF unit tests (partitions, leak checking setup/teardown functions, etc) are kept only in unit-test-app. Kconfig options are added to allow disabling certain Unity features.

newlib: Add adjtime - makes a gradual adjustment the system clock This function speeds up or slows down the system clock in order to make a gradual adjustment. This ensures that the calendar time reported by the system clock is always monotonically increasing, which might not happen if you simply set the clock. The delta argument specifies a relative adjustment to be made to the clock time. If negative, the system clock is slowed down for a while until it has lost this much elapsed time. If positive, the system clock is speeded up for a while. If the olddelta argument is not a null pointer, the adjtime function returns information about any previous time adjustment that has not yet completed. The return value is 0 on success and -1 on failure. To stop the adjustement, call the function settimeofday(current_time).

newlib: Add adjtime - makes a gradual adjustment the system clock This function speeds up or slows down the system clock in order to make a gradual adjustment. This ensures that the calendar time reported by the system clock is always monotonically increasing, which might not happen if you simply set the clock. The delta argument specifies a relative adjustment to be made to the clock time. If negative, the system clock is slowed down for a while until it has lost this much elapsed time. If positive, the system clock is speeded up for a while. If the olddelta argument is not a null pointer, the adjtime function returns information about any previous time adjustment that has not yet completed. The return value is 0 on success and -1 on failure. To stop the adjustement, call the function settimeofday(current_time).
