Set I2C speed to 88kHz, use digital filter only and reworked idle clock recovery
The errata describes a possible problem in operation between 88kHz and 100kHz => Set speed as recommended as work around.
Based on reference implementation only one filter should be use. Choice was digital because only drawback is lag of wakeup functionality which is not used
I2C communication may be randomly interrupted e.g. by a RTE reset or firmware update => reworked recovery function to get I2C devices in idle state again (Clk and SDA HIGH)
