As reported by MBED user Fran6Jack: I2C bus are usually 5V tolerant on all STM32 processor. If an external device on the I2C bus requires 5V operation, we usually acheive it by using 5V external pull-ups on the bus. Since signaling uses open-drain output on I2C for both signal SCL and SDA any 5V tolerant MCU will work on a 5V I2C bus. Having pull-up activated on a 5V externally pull bus, cause the pin to clamp on the STM32 die diode and could damage the IC (There is a note in STM32 datasheet specifying this issue). It is understood by all the community that I2C bus should always be externally pulled by physical resistor. I2C initialization should then be ALWAYS OpenDrainNoPull by default. Up to now, this I2C driver was setting pull up by default as it helps basic testing, like 1 master and 1 slave, conencted with 2 wires without any external pull ups. This will not work anymore after this commit and applications tests or examples needs to be modified to explicitely configure pull ups ... But it is safer to follow reference manual guidelines.
Fixed minor typos in test_api.py Added get_interface_version to detect_targets
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa. In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.
1. Remove stale code with mbed OS 3. 2. Remove check for busy peripherals unorganizedly. This would be supported by e.g. official sleep manager.

These power-down code are stale and would be superseded by sleep manager.
Previous the voltage range was set to 1.2 from SoC internal reference source. This caused problem with testing. It is unexpected that range is much shorter than vdd as well. The voltage range was extended using SoC build in analog prescaler (set to 1/3).
GCC's newlib library depends on fstat to get in-flight information about a file's type an size. A working fstat for regular files is needed for seek and related functions to work correctly.

1) if we receive more than one __sync, previous handshake would consider it as echo_count and try to decode the value. Now we skip superfluous __sync. 2) reduce the uart load produced by the test, as we are heavily running tests in parallel and not one-to-one this update was required.
